The Complete Guide to the Korean D-4 (General Training) Visa
I. The Big Picture
1. Overview of the D-4 Visa
The D-4 visa is a long-term status of stay granted to foreign nationals who intend to receive education or training, or to engage in research activities, at an educational institution, company, or organization meeting the requirements prescribed by the Minister of Justice (Enforcement Decree of the Immigration Act, Article 12, [Annex 1-2]).
Unlike the D-2 (Study Abroad) visa, the D-4 covers non-degree training programs rather than regular degree programs, with Korean language training at university-affiliated language institutes being the most common use case (Seoul Administrative Court, Judgment of Aug. 25, 2016, 2016Gudan11813).
2. Sub-Categories of the D-4 Visa
| Sub-Category | Content |
|---|---|
| D-4-1 | Korean language training at a university-affiliated language institute |
| D-4-2 | Foreign language training (foreign language education institution) |
| D-4-3 | Language institute training attached to elementary, middle, or high school |
| D-4-4 | Foreign school training |
| D-4-5 | Private language institute training |
| D-4-6 | Other educational institution training |
| D-4-7 | Corporate training |
3. Specific Requirements
A. Institutional Requirement
Institutions eligible for D-4 visa issuance are limited to educational institutions meeting the requirements prescribed by the Minister of Justice. For university-affiliated language institutes, the relevant university must be registered with the Ministry of Justice’s Foreign Student Information Management System (FIMS) (Seoul Administrative Court, Judgment of Aug. 25, 2016, 2016Gudan11813; Seoul Administrative Court, Judgment of Oct. 7, 2016, 2016Gudan54360).
B. Financial Capacity Requirement
Because D-4 visa holders are in principle prohibited from engaging in employment, they must have sufficient financial capacity to cover tuition fees, living expenses, and similar costs. Courts have stated the justification for this requirement as follows:
“Where an applicant for D-4 (General Training) status or an extension of the period of stay does not have sufficient financial capacity, there is a significant risk that the person will be tempted to engage in activities outside the status of stay such as employment, which would ultimately risk hollowing out the status-of-stay system.” (Seoul Administrative Court, Judgment of July 20, 2017, 2017Gudan58383; Seoul Administrative Court, Judgment of Dec. 21, 2018, 2018Gudan18306)
The requisite level of financial capacity is that which would enable a foreign national who has entered Korea to cover tuition fees and living expenses without engaging in activities outside the D-4 status of stay (Seoul Administrative Court, Judgment of July 20, 2017, 2017Gudan58383).
C. Attendance Rate Requirement
To obtain an extension of stay or a change of status under D-4, the holder must submit to the immigration office documentation showing an attendance rate of 70% or higher in the language training program (Suwon District Court, Judgment of Oct. 7, 2021, 2021Godan3072).
An attendance rate below 70% constitutes grounds for denial of extension of stay (Seoul Administrative Court, Judgment of Aug. 25, 2016, 2016Gudan11813; Seoul Administrative Court, Judgment of Jan. 12, 2017, 2016Gudan24857).
D. Clarity of Entry Circumstances and Purpose of Stay
The purpose of training must be clear when applying for a D-4 visa. Courts have held that a denial of change of status is lawful where the purpose of study is unclear, including in the following circumstances:
- Where an applicant entered on a short-term visit (C-3) visa and applied to change to D-4 without any particular change in circumstances (Seoul Administrative Court, Judgment of Nov. 18, 2016, 2016Gudan16306; Seoul Administrative Court, Judgment of Dec. 21, 2016, 2016Gudan18821)
- Where the applicant could have entered on a D-4 visa from the outset but instead entered on a C-3 visa (Seoul Administrative Court, Judgment of Oct. 7, 2016, 2016Gudan54360)
- Where the reason for needing to undergo Korean language training again after having already obtained a degree on a D-2 (Study Abroad) visa is unclear (Seoul Administrative Court, Judgment of Oct. 31, 2016, 2016Gudan17378)
4. Required Documents
A. Basic Documents
| Document | Notes |
|---|---|
| Visa application form | Hi Korea (www.hikorea.go.kr) or overseas mission |
| Passport | Validity of at least 6 months |
| Letter of admission | Issued by the relevant educational institution |
| Proof of financial capacity | Bank balance certificate, scholarship confirmation, etc. |
| Photograph | Meeting specifications |
B. Additional Documents for Extension of Stay
- Certificate of enrollment (stating attendance rate of 70% or higher)
- Academic transcript
- Proof of financial capacity (bank balance certificate, etc.)
C. Notes on Financial Capacity Documentation
Courts strictly scrutinize the authenticity of financial capacity documentation. The following circumstances have been held not to constitute proof of financial capacity:
- Where most of the funds were withdrawn immediately after the bank balance certificate was issued (Suwon District Court, Judgment of Oct. 10, 2018, 2018Gudan7123; Suwon District Court, Judgment of Oct. 10, 2018, 2018Gudan7147)
- Where funds were deposited and immediately withdrawn, creating only the appearance of financial capacity (Uijeongbu District Court, Judgment of Sept. 14, 2017, 2017Guhap11485)
- Where transaction records show primarily small transactions and living expenses, with no transactions evidencing genuine financial capacity (Suwon District Court, Judgment of Oct. 10, 2018, 2018Gudan7123)
5. Period of Stay
The period of stay under a D-4 visa is typically granted in increments of 6 months to 1 year, varying according to the duration of the training program. Extension applications must be filed before the period of stay expires, and attendance rate, financial capacity, and other requirements are subject to fresh review at each extension (Immigration Act, Article 25).
6. Key Cases
A. Denial of Change from C-3 to D-4
The Seoul Administrative Court upheld a denial of a change of status from short-term visit (C-3) to general training (D-4) as lawful on the following grounds: (i) the applicant fell within the category of persons whose change of status is restricted under Article 9(1)(1)(c) of the Enforcement Regulations of the Immigration Act; (ii) the applicant could have entered on a D-4 visa from the outset but instead entered on a C-3 visa; and (iii) the purpose of study was unclear (Seoul Administrative Court, Judgment of Nov. 18, 2016, 2016Gudan16306; Seoul Administrative Court, Judgment of Dec. 21, 2016, 2016Gudan18821; Seoul Administrative Court, Judgment of Nov. 4, 2016, 2016Gudan15174).
However, the Seoul Administrative Court also ruled in favor of a plaintiff in a case where, even though the applicant had entered on a C-3 visa, the applicant met all the requirements for D-4 status at the time of the application, holding that a refusal under those circumstances constituted a deviation from and abuse of discretion and was therefore unlawful (Seoul Administrative Court, Judgment of Apr. 7, 2017, 2016Gudan11554).
B. Cases Involving Falsified Attendance Records
The Suwon District Court convicted staff members of a private language institute for violating the Immigration Act, having caused foreign students enrolled under D-4 visa status to submit enrollment certificates falsely stating inflated attendance rates for the purpose of obtaining extensions of stay and changes of status (Suwon District Court, Judgment of Oct. 7, 2021, 2021Godan3072).
The Uijeongbu District Court similarly upheld as lawful a denial of extension of stay in a case where a language institute had processed Friday absences as attendance when no classes were actually held on Fridays, resulting in the issuance of falsified enrollment certificates (Uijeongbu District Court, Judgment of Sept. 14, 2017, 2017Guhap11485).
C. Denial of Change to D-2 for Insufficient Financial Capacity
The Suwon District Court upheld as lawful a denial of a change of status from D-4 to D-2 (Study Abroad) following completion of language training, where the applicant had withdrawn most of the funds immediately after the bank balance certificate was issued, creating only the appearance of financial capacity and failing to constitute genuine proof of financial means (Suwon District Court, Judgment of Oct. 10, 2018, 2018Gudan7123).
D. Criminal Punishment for Brokering Illegal Employment
The Gwangju District Court Suncheon Branch sentenced a defendant to a fine of KRW 15 million for violating the Immigration Act by placing a foreign national who had entered on D-4-1 (university-affiliated language institute training) status in employment despite the foreign national not being permitted to engage in employment (Gwangju District Court Suncheon Branch, Judgment of June 16, 2021, 2019Gojeong92).
E. Obstruction of Official Duties by Deception
The Suwon District Court sentenced a defendant to a fine of KRW 2 million for obstruction of official duties by deception in a case where the defendant, having entered on a D-4-1 visa and applied for a change of status to D-2-2 (bachelor’s degree study), submitted a false bank balance certificate with the application (Suwon District Court, Judgment of Sept. 18, 2025, 2025Gojeong279).
The Supreme Court has held in this regard that where an applicant makes a false representation to the officer in charge and submits supporting materials consistent with that representation, the offense of obstruction of official duties by deception is established if the officer, having conducted a thorough review, nonetheless failed to detect the falsity and accepted the application (Supreme Court, Judgment of Apr. 28, 2011, 2010Do14696).
F. Restriction on F-3 (Dependent Family) Status for Spouses
The Daegu District Court upheld as lawful a denial of a change of status to F-3 (Dependent Family) for a spouse sought to be invited by a person holding D-4 (language training) status, on the ground that, under Ministry of Justice guidelines, holders of D-4 status with a period of stay of 2 years or less are restricted from inviting spouses and children absent humanitarian grounds (Daegu District Court, Judgment of July 17, 2020, 2020Gudan645).
7. Obligations After Obtaining the Visa
A. Restriction on Employment Activity
D-4 visa holders are in principle prohibited from engaging in employment. However, holders of D-4-1 (university-affiliated language institute training) status are permitted to engage in employment on a limited basis where they have met the relevant requirements and obtained part-time employment permission from the competent authority (Gwangju District Court Suncheon Branch, Judgment of June 16, 2021, 2019Gojeong92).
By contrast, certain sub-categories such as D-4-3 (language institute training attached to elementary, middle, or high school) may be excluded from eligibility for part-time employment permission, and caution is accordingly warranted.
B. Obligation to Maintain Attendance Rate
To obtain an extension of stay or a change to another status such as D-2, an attendance rate of 70% or higher must be maintained. A poor attendance record constitutes grounds for denial of extension of stay (Seoul Administrative Court, Judgment of Jan. 12, 2017, 2016Gudan24857).
C. Ongoing Maintenance of Financial Capacity
Because the financial capacity requirement is subject to fresh review at each extension of stay, it is important to maintain genuine financial capacity throughout the period of enrollment and to manage documentation capable of proving it. Withdrawing most of the funds immediately after a bank balance certificate is issued not only fails to constitute proof of financial capacity but may also be assessed as submission of false documentation (Suwon District Court, Judgment of Oct. 10, 2018, 2018Gudan7123).
D. Change of Status to D-2
Where a foreign national wishes to enroll in a regular degree program after completing language training and change status to D-2, a standard certificate of admission containing determinations on academic ability and financial capacity must be submitted, and the financial capacity requirement must be satisfied. In particular, where the applicant is enrolling at a university designated as a restricted or supervised institution, stricter review standards apply (Suwon District Court, Judgment of Oct. 10, 2018, 2018Gudan7123).
E. Prohibition on Submitting False Documents
Submitting false financial capacity documentation or enrollment certificates containing falsified attendance rates in connection with an extension of stay or change of status application may result in criminal punishment for violations of the Immigration Act and for obstruction of official duties by deception (Supreme Court, Judgment of Apr. 28, 2011, 2010Do14696; Suwon District Court, Judgment of Sept. 18, 2025, 2025Gojeong279).
8. Notes on Deviation from or Abuse of Discretion
Although a permit to change status of stay is a constitutive administrative disposition over which the authorizing authority has discretion, a decision is unlawful as a deviation from or abuse of discretion where the applicant has met the requirements set out in the relevant statutes and there is a serious error in the factual findings, the principles of proportionality or equality have been violated, or the decision is so manifestly unreasonable as to fall outside generally accepted social norms (Seoul Administrative Court, Judgment of Oct. 7, 2016, 2016Gudan54360; Seoul Administrative Court, Judgment of Nov. 4, 2016, 2016Gudan15174).
Where a denial has been issued, it is possible to challenge the decision through an administrative appeal or administrative litigation by examining whether there was a factual error or a violation of the principle of proportionality. However, unless the denial has resulted in an entry ban or similar measure, the applicant may re-enter lawfully by satisfying the requirements anew, meaning that a denial does not necessarily entail a permanent disadvantage (Seoul Administrative Court, Judgment of Dec. 9, 2016, 2016Gudan58829; Uijeongbu District Court, Judgment of Sept. 14, 2017, 2017Guhap11485).
II. Part-Time Employment Permission Requirements for D-4 Visa Holders, and Comparison with the D-2 Visa
1. Legal Basis for Part-Time Employment Permission for D-4 Visa Holders
A foreign national staying in Korea who wishes to engage, alongside the activities corresponding to their status of stay, in activities corresponding to a different status of stay must obtain prior permission from the Minister of Justice for activities outside the status of stay (Immigration Act, Article 20).
Because holders of D-4 (General Training) status are in principle prohibited from engaging in employment, they must obtain this permission in advance before taking up any part-time employment. In this regard, Article 72(2) of the Enforcement Regulations of the Immigration Act sets the fee for permission for activities outside the status of stay — in cases of part-time employment permitted to holders of D-2 (Study Abroad) or D-4 (General Training) status — at KRW 20,000, which is lower than the standard fee of KRW 120,000. This provision expressly confirms that both statuses of stay are subject to the part-time employment permission system (Enforcement Regulations of the Immigration Act, Article 72(2)).
2. Specific Requirements for Part-Time Employment Permission for D-4 Visa Holders
The reference materials provided do not include cases or statutory provisions that directly set out the part-time employment permission requirements for D-4 visa holders. However, in a judgment of the Incheon District Court concerning the part-time employment permission requirements for holders of D-4-6 (private educational institution training) status, the following was confirmed:
“The Ministry of Justice issues ‘D-4-6’ visas to foreign nationals on the condition that they receive training at a private educational institution meeting certain requirements. From January 2, 2017, the Ministry added as a mandatory requirement that the foreign national possess the Korean language ability necessary for training (TOPIK Level 2 or higher as administered by the National Institute for International Education, or Social Integration Program Level 2 or higher).” (Incheon District Court, Judgment of Mar. 26, 2019, 2018Godan7625)
Based on the Ministry of Justice’s “Integrated Guidelines on Visa Issuance and Stay Management for Foreign Students,” the practical requirements for part-time employment permission for holders of D-4-1 (university-affiliated language institute training) status are summarized as follows.
A. Part-Time Employment Permission Requirements for D-4-1 Holders
| Requirement | Standard |
|---|---|
| Korean language proficiency | TOPIK Level 2 or higher (for D-4-1) |
| Training period | Eligible to apply after at least 6 months of training |
| Attendance rate | 70% or higher in the immediately preceding term |
| Application method | Obtain confirmation from the institution’s designated officer, then apply through Hi Korea |
B. Availability of Part-Time Employment Permission by D-4 Sub-Category
Part-time employment permission is not available for all D-4 sub-categories. Certain sub-categories — such as D-4-3 (language institute training attached to elementary, middle, or high school) and D-4-4 (foreign school training) — may be excluded from eligibility for part-time employment permission, and caution is accordingly warranted.
3. Part-Time Employment Permission Requirements for D-2 Visa Holders
The part-time employment permission requirements for D-2 visa holders are as follows.
| Requirement | Standard |
|---|---|
| Korean language proficiency | TOPIK Level 3 or higher |
| Academic performance | Grade point average of C or higher in the immediately preceding semester |
| University officer confirmation | Confirmation required from the foreign student officer at the university attended |
These requirements derive from the Ministry of Justice’s “Integrated Guidelines on Visa Issuance and Stay Management for Foreign Students” and are confirmed in case law (Suwon District Court, Judgment of Jan. 13, 2022, 2020Godan5134).
4. Comparison of Part-Time Employment Permission Requirements: D-4 vs. D-2
| Item | D-4 (General Training) | D-2 (Study Abroad) |
|---|---|---|
| TOPIK requirement | Level 2 or higher (D-4-1 standard) | Level 3 or higher |
| Academic performance | Attendance rate of 70% or higher | Grade point average of C or higher |
| Training/enrollment period | Eligible after 6 or more months of training | No separate minimum period |
| Officer confirmation | Confirmation from institution’s designated officer | Confirmation from university’s foreign student officer |
| Permission fee | KRW 20,000 | KRW 20,000 |
| Legal basis | Enforcement Regulations of the Immigration Act, Article 72(2) | Enforcement Regulations of the Immigration Act, Article 72(2) |
A. Difference in TOPIK Requirements
The most significant difference is the TOPIK requirement. D-2 visa holders must hold TOPIK Level 3 or higher, whereas D-4-1 visa holders face a relaxed threshold of Level 2 or higher. This is understood to reflect the purpose of the D-4 status — which is itself for the purpose of Korean language training — such that a certain level of Korean language ability at an early stage of training is sufficient to permit part-time employment.
B. Difference in Academic Performance Requirements
D-2 visa holders are explicitly required to have maintained a grade point average of C or higher in the immediately preceding semester (Suwon District Court, Judgment of Jan. 13, 2022, 2020Godan5134). By contrast, for D-4 visa holders, the primary academic maintenance requirement is an attendance rate of 70% or higher, in place of a grade-based standard.
C. Common Features
Both statuses share the following: (i) employment is permitted only within the authorized scope; (ii) engaging in employment without permission or exceeding the authorized scope may result in criminal punishment — imprisonment of up to 3 years or a fine of up to KRW 30 million — for violation of the Immigration Act (Immigration Act, Article 94(12)); and (iii) such violations may constitute grounds for denial of extension of stay.
5. Practical Considerations
A. Risks of Unauthorized Employment
A D-4 visa holder who engages in employment without part-time employment permission may be punished for violating the Immigration Act. In one reported case, an employer who placed a foreign national holding D-4-1 status in employment despite the foreign national not being permitted to engage in employment was sentenced to a fine of KRW 15 million (Gwangju District Court Suncheon Branch, Judgment of June 16, 2021, 2019Gojeong92).
B. Permission Fee
The part-time employment permission fee for holders of D-2 and D-4 status is set at KRW 20,000 — significantly lower than the standard fee of KRW 120,000 for other permissions for activities outside the status of stay — reflecting a policy of encouraging lawful part-time employment by foreign students and trainees (Enforcement Regulations of the Immigration Act, Article 72(2)).
C. Need to Verify Current Requirements
Because the Ministry of Justice’s “Integrated Guidelines on Visa Issuance and Stay Management for Foreign Students” is an internal administrative discretionary guideline that is subject to revision at any time, it is essential to verify the current requirements through Hi Korea (www.hikorea.go.kr) or the competent immigration office before filing an application.
III. Legal Liability and Administrative Consequences for D-4 Visa Holders Who Exceed the Authorized Scope of Part-Time Employment
1. The Issue
Holders of D-4 (General Training) status are in principle prohibited from engaging in employment, but are permitted to do so on a limited basis where they have met the relevant requirements and obtained part-time employment permission (Gwangju District Court Suncheon Branch, Judgment of June 16, 2021, 2019Gojeong92). Where, however, an authorized holder engages in employment beyond the authorized scope, this gives rise to a distinct set of legal issues separate from those of unauthorized employment without any permission at all.
Article 20 of the Immigration Act requires prior permission for activities outside the status of stay, and employment that exceeds the scope of such permission constitutes a violation of the conditions of the permission and accordingly a violation of the Immigration Act (Immigration Act, Article 20; Enforcement Decree of the Immigration Act, Article 23(1)).
2. Criminal Liability
A. An Immigration Act Violation
Employment that exceeds the authorized scope is evaluated as engaging in activities corresponding to a different status of stay without permission for activities outside the status of stay, and may result in imprisonment of up to 3 years or a fine of up to KRW 30 million under Article 94(12) and Article 20 of the Immigration Act.
The Incheon District Court recognized a violation of the Immigration Act in a case where a holder of D-2 (Study Abroad) status who had obtained part-time employment permission engaged in employment exceeding the authorized scope (Incheon District Court, Judgment of Feb. 5, 2021, 2020Gudan51393):
“The plaintiff had obtained permission for part-time employment in office support work at a daily rate of KRW 60,000 from June 4 to September 30, 2019, but in substance was engaged in customer solicitation activities and received commissions, thereby engaging in employment beyond the authorized scope.”
B. Employment in an Unauthorized Industry
Employment in an industry other than the one authorized likewise constitutes a violation of the Immigration Act. The Jeonju District Court recognized an Immigration Act violation in a case where a D-2 status holder who had previously obtained part-time employment permission and worked at a restaurant subsequently engaged in employment in a different industry without authorization (Jeonju District Court, Judgment of July 11, 2024, 2023Guhap12146).
C. Likelihood of Intentional Element Being Established
Because a foreign national who has obtained part-time employment permission is already aware of the content and scope of the permission, the intentional element is very likely to be established where employment exceeds the authorized scope. The Jeonju District Court held in this regard:
“The plaintiff was well aware of the scope of permitted activities under D-2 (Study Abroad) status, the procedure for applying for permission for activities outside the status of stay, the validity period of such permission, and its content.”
(Jeonju District Court, Judgment of July 11, 2024, 2023Guhap12146)
3. Administrative Consequences
A. Becoming Subject to Deportation
Employment that exceeds the authorized scope makes the person subject to deportation under Article 46(1)(8) of the Immigration Act. The Jeonju District Court expressly held:
“The head of the regional immigration office may deport from Korea a foreign national who has engaged in employment without having obtained a status of stay permitting employment or having obtained permission from the Minister of Justice for activities outside the status of stay permitting employment, pursuant to Article 46(1)(8), Article 18(1), and Article 20 of the Immigration Act.”
(Jeonju District Court, Judgment of July 11, 2024, 2023Guhap12146)
B. Departure Order
Even where a person is subject to deportation, expressing a willingness to depart voluntarily may result in a departure order being issued instead. The Incheon District Court upheld as lawful a departure order — issued by the defendant immigration authority rather than a deportation order — against a D-2 status holder who had engaged in employment beyond the authorized scope (Incheon District Court, Judgment of Feb. 5, 2021, 2020Gudan51393).
C. Denial of Change of Status or Extension of Stay
Where employment beyond the authorized scope is confirmed, a permit to change status of stay or to extend the period of stay may be denied. The Daegu District Court upheld as lawful a denial of extension of stay in a case where a D-2 status holder continued to work at the establishment where they had previously held part-time employment permission, without authorization, after changing their status of stay:
“The plaintiff engaged in simple manual labor unrelated to job-seeking activities for approximately 3 of the 6 months of stay authorized under D-10 (Job Seeker) status; the degree of the violation cannot be regarded as minor. Moreover, despite unauthorized employment constituting a violation of the Immigration Act for which deportation would be applicable, the plaintiff received no sanction other than the disposition in this case.”
(Daegu District Court, Judgment of Nov. 22, 2019, 2019Gudan10806)
D. Penalty Notice
Even where the matter does not rise to the level of deportation, a penalty notice imposing a fine may be issued. Under the Ministry of Justice’s “Integrated Guidelines on Visa Issuance and Stay Management for Foreign Students,” where unauthorized employment is first detected and a penalty notice is issued but continued stay is permitted, part-time employment permission is restricted for one year from the date of payment of the fine; from the second detection onward, deportation is applied as the default without exception (see Seoul Administrative Court, Judgment of May 23, 2024, 2023Gudan70513).
E. Conversion to Deportation Order Upon Non-Compliance with Departure Order
Where a foreign national who has received a departure order fails to depart by the designated deadline, the head of the regional immigration office must issue a deportation order without delay, meaning the act becomes one of bound discretion in such cases (Immigration Act, Article 68(4)).
4. Employer’s Legal Liability
An employer who engages a D-4 visa holder in employment beyond the authorized scope may also be subject to imprisonment of up to 3 years or a fine of up to KRW 30 million under Article 94(9) of the Immigration Act (Immigration Act, Article 94(9) and Article 18(3)).
However, the mere fact that an employee of a corporation employed an unqualified foreign national, and that the corporation’s representative director was in a position where they could have been aware of this, does not by itself make the representative director a person who “employed” the foreign national within the meaning of Article 94(9) of the Immigration Act (Supreme Court, Judgment of June 29, 2017, 2017Do3005).
Below, general immigration and safety information D-4 visa holder students studying in Korea, regardless of which institution they attend.
1. Alien Registration Card (ARC)
- Required for stays longer than 90 days
- Deadline: within 90 days of entry into Korea
- Required documents: passport, 1 photo (3×4cm), certificate of enrollment, tuition receipt, application form, proof of residence
- Fee: KRW 35,000 (individual application at an Immigration Office; group applications through a school may cost more)
- Individual applications require an advance reservation at the Immigration Office — walk-ins without a reservation are not accepted
2. Visa Extension
- Apply at least 2 weeks before the visa expires
- Required documents: passport, ARC, certificate of enrollment, tuition receipt, proof of residence, application form
- Fee: KRW 60,000
- If attendance falls below a certain threshold, immigration may require a bank statement showing a minimum balance (commonly cited around 5 million KRW) as added proof of financial capacity
3. Part-Time Work Permission
- Must apply for permission before working — either at a local Immigration Office (by reservation) or online via Hi Korea (www.hikorea.go.kr)
- Required document: Part-time Work of Foreign Student Confirmation Form (downloadable from Hi Korea)
- General eligibility: D-4 visa holders must have been in Korea for 6+ months, and must meet a minimum attendance-rate threshold from their school
- Work hour limits:
- TOPIK Level 2 or higher: up to 25 hrs/week (including weekends/vacation)
- Below TOPIK Level 2: up to 10 hrs/week
- Penalty for illegal work: fine of ₩2,000,000 + deportation
4. Attendance & Immigration Reporting (per Korean Immigration Law)
- Students with 10 or more consecutive unexcused absences may be dismissed from their program and reported to the Korea Immigration Service
- Engaging in illegal work (violating visa conditions) or violating Korean law can result in dismissal, D-visa cancellation, and partial tuition refund only
5. National Health Insurance
- Foreign students are automatically enrolled in Korea’s National Health Insurance 6 months after their date of entry
- The payment notice is sent to the address registered on your ARC — you must pay individually
- Failure to pay can negatively affect visa extension and continued stay in Korea
- Check your insurance status at the NHIS website: https://www.nhis.or.kr/nhis/index.do (Inquiry line: +82-33-811-2001)
6. Financial Safety / Scam Awareness
- Voice phishing: Scammers may impersonate police or government officials — never share personal information with suspicious callers; report such calls to your school or local authorities
- Money exchange scams: Avoid unusually high exchange rates offered by unlicensed brokers, as the funds could be tied to illegal activity — use reputable banks for currency exchange
- Account selling/lending: Never lend or sell your bank account — doing so can make you criminally liable for money laundering
If you are in South Korea on a D-4 visa to learn Korean, the single most important thing you can do this year is exactly that: learn Korean. Not find the fastest way to earn money. Not switch to an “easy” school. Learn the language.
Korean is hard, but it can be learned. Many foreigners who now build careers in Korea started exactly where you are: as adults, with little or no Korean.
If they could learn it, so can you. This guide explains why it matters so much, the traps that catch D-4 students every year, and three simple goals for your year in Korea.
Key Takeaways
- In Korea, your Korean decides your future — more than your visa type or your degree.
- Transferring to an “easy” D-2 school that sells degrees taught in English usually ends badly.
- Working without a permit is a crime. Since October 2026, students caught working illegally in delivery or entertainment jobs face deportation or a departure order — even the first time.
- Your three goals: attend 90% or more of your classes, get good grades, and pass TOPIK 2, then TOPIK 4.
[Opinion] Korean Is Your Key: A Survival Guide for D-4 Language Students in South Korea
Why Korean matters more than your degree
Korea now has a record 274,329 international students, up 41,092 (17.6%) in a single year, according to the Ministry of the Interior and Safety (CBS Nocut News, 28 Oct 2026). Every year, more foreign graduates compete for the same jobs. A degree alone no longer makes you stand out. Korean does.
Employers are clear about this. Large companies such as Samsung and SK use their own aptitude tests written only in Korean, and foreign graduates are told to apply through the same open recruitment as Korean applicants, with interviews in Korean (Korea Herald via Asia News Network).
Without Korean: real stories
- “Meena.” After finishing her language course, she found a hotel dishwashing job. She was let go after a few days because her Korean was not good enough (The Annapurna Express).
- Yonsei graduates. A Chinese Yonsei University graduate told the Korea Herald that she knows university friends who struggle to find work because they do not speak Korean (Korea Herald via ANN).
With Korean: doors open
- A KAIST master’s graduate found a job within three months. The company asked for TOPIK level 5, and her later interviews were in Korean (Korea Herald via ANN).
- GKS scholars, Korea’s top government scholarship students, all study Korean for a full year before starting their degree. Many reach TOPIK 5 or higher, and employers actively seek them out (KOWORK).
The “easy D-2 school” trap
A common story: a student comes to Korea on D-4 to learn Korean, then a friend or an agent suggests quitting the language course and transferring on a D-2 visa to a little-known university. The BA is taught in English, you only attend once or twice a week, and you can work the rest of the time. In practice, these schools are selling the D-2 visa, not an education.
| What they promise | What you are really buying |
|---|---|
| “Move to a small, unknown university on a D-2 visa.” | A visa, not an education. |
| “The BA is taught in English — no Korean needed.” | After four years in Korea, still no Korean — the one thing employers ask for. |
| “Go to class once or twice a week.” | Low attendance gets visa extensions refused. Immigration watches these schools. |
| “Work the rest of the week and make money.” | Illegal work leads to a departure order or deportation — even one delivery job. |
Both governments involved are closing this loophole. In February 2026, Korea’s Ministry of Justice and Ministry of Education restricted new student visas for one year at 20 schools from the autumn 2026 semester (MOJ press release). From 2029, universities that fail quality or financial standards will be barred from recruiting new international students (Hankyoreh). When a school loses its status, it is the students whose visa extensions are refused.
Where each road ends
| The “easy” D-2 school | The language-school road | |
|---|---|---|
| How you spend the year | English BA at an unknown school, class once or twice a week | 90%+ attendance, good grades |
| What you gain | Work hours, little or no Korean | TOPIK 2, then TOPIK 4 |
| Where it ends | A weak degree, no Korean, no job visa — and often a ticket home with debt | Korean, a respected degree, and a real future in Korea |
Real students have already taken this road. “Vishal” from Pokhara paid Rs 1.7 million through a consultancy, lost his visa, and now works illegally; two of his friends were arrested at work and deported. “Mohan” was sent with 115 other students to one college; he came to study AI, but the college does not teach it, so he was put in taekwondo classes (The Annapurna Express). If it sounds too easy, it is a trap.
Working without a permit: what the law says
D-4 is a study visa, and working is not allowed unless immigration gives you a part-time work permit first. Under the Immigration Act, D-2 and D-4 are not statuses that allow employment, so a student needs advance permission for “activities outside their status of stay” (Article 20), with confirmation from their school. Even with a permit, delivery riding, construction and manufacturing (E-9 sectors) are off limits.
One delivery job can end your stay. On 29 October 2026, the Ministry of Justice, the police and other agencies agreed a joint crackdown on illegal foreign delivery riders. Immigration tightened its standard: students caught working illegally in delivery or entertainment jobs will, in principle, receive deportation or a departure order, no matter how many times they were caught. Police will also investigate delivery agencies that hire illegally and riders who use someone else’s account (Money Today, 30 Oct 2026). Borrowing a friend’s delivery account is exactly what is being investigated.
Working without a permit has three consequences:
- It is a crime. You can be punished by up to three years’ imprisonment or a fine of up to KRW 30 million (Article 94). Employers and brokers who arrange the work are punished too (Articles 18 and 94).
- You may have to leave Korea. Illegal work is a ground for deportation (Article 46). Immigration may instead issue a departure order (Article 68). If you do not leave by the deadline, it becomes a deportation order.
- Your future is blocked. A record of illegal work weighs heavily against visa extensions and changes. A fine or penalty of KRW 400,000 or more for an employment-related violation blocks a change to the D-10 job-seeker visa for five years (Daejeon District Court, 2021Gudan101880).
Money earned illegally also cannot be used as proof of funds for an extension, and withdrawing money right after getting a bank balance certificate raises doubts (Seoul Administrative Court, 2018Gudan54340).
Real court cases
| Case | What happened | Outcome |
|---|---|---|
| D-4 language student (Suwon District Court, 2019Gudan8444, 2020) | Worked at a mobile phone shop without a permit. Attendance was 66% and grades were failing. | Departure order and refusal of the visa change both upheld. |
| “I read it online” (Suwon District Court, 2024Gudan12492, 2025) | Read an immigration website notice about working 20 hours a week and started working without a permit. | No protection: the notice assumed a permit. |
The lesson from these cases: courts look at three things — attendance, grades, and illegal work. “I thought it was OK” is not an excuse. No permit means illegal work.
Your 3 goals for the year
Focus on three goals, in this order: attend 90% or more of your classes, get good grades, and pass TOPIK 2, then TOPIK 4. Hit the first two every term and the third follows.
Goal 1: Attend 90% or more — every term
Attendance is not just a school rule. It is the number immigration looks at, and courts treat it as proof that you are a genuine student. Rules differ by school, so check your own institute’s regulations, but this is how attendance typically affects you:
- Part-time work: a part-time work permit usually requires high attendance (90% or more at many schools) in every term you have completed.
- Passing your level: most language institutes require around 80% attendance to complete a level.
- Visa extension: low attendance can mean extra proof of funds or a refused extension.
- Staying enrolled: long unexcused absences can get you dismissed, and your school must report it to immigration.
In Korea, one minute late is late. If class starts at 9:00, 9:01 is late. At many schools, a few late arrivals count as one absence, so being a little late every day quietly destroys your attendance. Always plan to arrive 5–10 minutes early.
Skipping class to earn money is a trap: attendance falls below the required level, you lose the right to a legal work permit, and illegal work can end with a fine, deportation and dismissal. Habits that help: choose a class time you can really keep, find a classmate to check on each other, check your attendance record every week, and if you are sick, see a doctor and keep the note.
Goal 2: Good grades
Most language institutes grade you on midterm and final exams plus homework and participation, and you must pass each level to move up. Homework and participation are the easiest points you will ever earn, so never skip them.
Good grades matter beyond the classroom. You move up one level each term, and failing the same level repeatedly can end your enrolment. Your transcript goes with your visa extension and your university applications. Some universities also accept their own language institute’s completion certificate in place of a TOPIK score.
Goal 3: TOPIK 2 first, then TOPIK 4
| Level | Goal | What it opens |
|---|---|---|
| TOPIK 2 | Start | More legal part-time work hours on D-4 (without it, only 10 hours a week); proof you can live and work in basic Korean |
| TOPIK 3 | Next | Admission to many Korean universities; a strong base for degree study |
| TOPIK 4 | Goal | Good universities and real internships (Hyundai, SK hynix and Nongshim ask for TOPIK 4); a strong case for a job visa later |
Sit the test at every round so you always know where you stand, and register the day registration opens on topik.go.kr, as seats fill fast. Part-time hours and other rules change, so always confirm the current limits on HiKorea or by calling 1345 before you start a job.
Your year at a glance
Most university language institutes run four 10-week terms a year.
| Term 1 | Term 2 | Term 3 | Term 4 | |
|---|---|---|---|---|
| 1. Attendance | 90%+ | 90%+ | 90%+ | 90%+ |
| 2. Your level | Pass | Pass | Pass | Pass |
| 3. TOPIK | Learn Hangul and basics | TOPIK 2 | TOPIK 3 | TOPIK 4 |
Part-time work becomes possible only after about six months in Korea, and only with a permit.
Remember why you are here
You came to Korea to learn Korean and to build a real future. Fast money now can cost you that whole future. One honest year of Korean opens doors that no shortcut can.
Show up. Study. Pass. Your future in Korea starts in your classroom. Stay focused, study hard, and make your family proud.
Where to get help
Always ask when in doubt — before you sign anything, change schools, or start any job. A question costs nothing; a mistake can cost your visa.
