Korean Language School (D-4) vs. Undergraduate and Graduate Programs (D-2) — Period of Stay, Part-Time Work, and Extension Rules All Differ

"I'm going to Korea to study" is one sentence, but on immigration paperwork it splits into two tracks. If you attend a university-affiliated Korean language school (어학당), you're on General Training (D-4); if you're in a regular undergraduate or graduate degree program, you're on Study Abroad (D-2). People lump both together as a "student visa," but the period of stay you get at one time, when you can start part-time work and for how many hours, and what the extension review looks at are all different.

If you don't know the difference, your plans get out of order. You read reviews from degree students and think, "I'll just earn it all during vacation," only to find that rule doesn't apply to language school students at all. Or you assume that finishing one year of language school automatically moves you up into an undergraduate program. The bigger trap is that the step where your visa starts isn't in your hands. Even if you've been accepted by a language school and paid tuition, the application doesn't open until the school uploads your documents to the system.

What follows is based on laws, guidelines, and official university information checked as of September 2026. Each source has a different reference date, so we've noted it alongside each statement. This isn't legal advice, and whether you get a permit depends on the review by the regional immigration office with jurisdiction. Before you apply, check the current rules with HiKorea (www.hikorea.go.kr), ☎1345 (Immigration Contact Center, 20 languages), and the international office of the university you're applying to.

Two visas hide inside the same word, "study"

The starting point is the law. Appended Table 1-2 of the Enforcement Decree of the Immigration Act (amended May 27, 2025) defines the two statuses like this.

• Study Abroad (D-2) — a person who intends to receive regular-program education, or to conduct specific research, at an educational institution at the junior college level or above or at an academic research institution
• General Training (D-4) — a person who intends to receive education or training, or to engage in research activities, at an educational institution, company, organization, or the like that meets the requirements set by the Minister of Justice

What's easy to miss is the parenthetical after the D-4 definition. It expressly excludes people who receive pay exceeding their living expenses from the training institution, as well as anyone who falls under Study Abroad (D-2) or Technical Training (D-3). In other words, D-4 is a residual status that exists only when you don't qualify for D-2. So which one you get isn't your choice; the nature of the institution you attend decides it. A combination like "tuition is cheaper, so I'll get D-4 and take undergraduate classes" doesn't work.

The sub-codes split too. The Ministry of Justice "Guidelines on Visa Issuance and Stay Management for International Students" (public version, fully revised March 1, 2018) divides D-2 into D-2-1 associate degree, D-2-2 bachelor's, D-2-3 master's, D-2-4 doctoral, D-2-5 research, D-2-6 exchange student, D-2-7 work-study linked, and D-2-8 short-term study, and puts language training under D-4-1 Korean language training and D-4-7 foreign language training. You can see the split in the numbers, too. According to the Ministry of Education and Korean Educational Development Institute's "2026 Basic Education Statistics," international students at higher education institutions in Korea numbered 307,464 as of April 1, 2026, passing 300,000 for the first time (223,191 in degree programs and 84,273 in non-degree programs such as language training and exchange programs). That's about 72.6% in degree programs and about 27.4% in non-degree programs; a year earlier, in 2025, the total was 253,434.

Where you study decides your status

The institutions eligible for D-4 language training are university-affiliated language institutes. The Ministry of Education's "Standard Procedures for Handling International Students and Language Trainees" (amended March 27, 2026) defines these as institutes that fall under the authority and responsibility of the university president or dean and are, in principle, located inside the university. Enrolling at a private Korean language academy you see on the street doesn't count.

Even among "university-affiliated" institutes, there's another split. The Ministry of Education's Standard Procedures make direct operation by the university the rule and discourage outsourced operation, and they state explicitly that for institutes run by an outside operator, visa issuance may not be possible under the Ministry of Justice guidelines. Promotional materials alone rarely tell you whether an institute is run directly or outsourced, so before you enroll, ask the university's international office or the language institute's office who operates it.

The class structure differs, too. Going by information from Yonsei, Kyungpook National, and Hannam universities, one language school term is typically 10 weeks and 200 hours (Monday to Friday, 4 hours a day). Terms are short and packed, so missing just a few days pulls your attendance rate down fast. The Korean-language requirements differ as well: the university admission standard the Ministry of Education recommends (TOPIK Level 3 or higher for four-year universities and graduate schools, Level 2 or higher for junior colleges) does not apply to language trainees entering a language training institute. You can get into a language school even with no Korean at all, which is why the language school serves as the entry point.

Period of stay — the cap is 2 years for both, but what you actually get differs

The legal cap is the same. Appended Table 1 of the Enforcement Rules of the Immigration Act (amended December 24, 2024) sets the same maximum period of stay granted at one time for both: 2 years for Study Abroad (D-2) and 2 years for General Training (D-4). In practice, though, the period you're given differs. The Ministry of Justice guidelines (public version fully revised March 1, 2018, standard for certified universities) break it down like this.

For degree programs, if a student at a certified university has an average of C (2.0 GPA) or higher, the extension is in principle processed without collecting documents (academic records are checked through the International Student Information System (FIMS), and proof of finances is skipped), and 2 years are granted. However, the 2018 public version excludes nationals of countries designated by public notice of the Minister of Justice from this maximum-period rule, and says it applies to all nationalities only at certified universities with an illegal-stay rate below 1%.

Language training is granted in 6-month blocks, and you apply again each time. Each extension adds up to 6 months, and the new period can run no more than 15 days past the course end date. Kyungpook National University's Language Education Center and Youngsan University's Korean Language Education Center also note that "only 6 months are granted at first, and you need to apply for an extension if you want to keep studying." With 10-week terms, that works out to one extension about every two terms.

There's also an overall limit. The guidelines allow stay for language training purposes for a maximum of 2 years only, and university notices likewise describe extensions in 6-month units for up to 2 years. The route of attending only a language school runs out at some point. For degree programs too, if your total period of stay has passed 3 years for an associate degree, 4 years for a bachelor's, or 5 years for a master's or doctorate, and you have frequent changes in academic status such as switching majors or transferring schools, permission to stay is restricted in principle.

Money — school fees, tuition, and your visa bank balance are all different numbers

The financial-capacity standard reviewed for your visa differs by program and by where the university is located. These figures come from the Ministry of Education's Standard Procedures (amended March 27, 2026) and reflect the separate standard for universities outside the capital region that the Ministry of Justice introduced when it switched from dollar-based to won-based amounts on July 3, 2023. Under general law, the capital region (수도권) means Seoul, Incheon, and Gyeonggi, but the public source text doesn't say whether the visa standard uses exactly that scope. If your university is in Incheon or Gyeonggi, check with the university's international office and the Korean embassy or consulate that handles your application.

The language training standard applies regardless of the length of your stay. These amounts are review thresholds covering tuition and living expenses combined, and the required documents can vary with the university's certification grade and your nationality. Pusan National University's Language Education Institute uses the same number in its D-4-1 guidance: a bank balance certificate of 8,000,000 KRW or more. As a rule, the bank balance certificate must have been issued within 30 days before the application date (a certificate that states its own validity period is accepted for up to 6 months from issuance), and if the university's admission guide or the embassy or consulate asks for a shorter window, follow the instructions of wherever you're submitting it. If you submit one in a parent's name, you must also submit a family relationship certificate; but when you prove your finances inside Korea, such as for an extension of stay or a change to D-2 after language training, only a bank balance certificate in your own name issued by a bank in Korea is accepted (per the 2018 public version of the Ministry of Justice guidelines). For the order of preparation, see the foreign document checklist for Korean visas.

There's a distinction to make here. The bank balance for your visa review and the fees you actually pay are different numbers. We've calculated the full one-year total, including tuition, dormitory fees, and health insurance premiums, separately in What a Year of Studying in Korea Actually Costs. Language school fees vary by university; for the 6 schools whose language school notices we checked in September 2026, the range per term (usually 10 weeks) is about 1,400,000–1,860,000 KRW.

• Kyungpook National University Language Education Center 1,400,000 KRW · Hannam University Korean Language Education Center 1,400,000 KRW
• Pusan National University Language Education Institute 1,500,000 KRW · Chung-Ang University Language Education Institute, Davinci Campus 1,500,000 KRW / Seoul Campus 1,700,000 KRW
• Seoul National University Language Education Institute, Korean Language Education Center: regular afternoon class 1,650,000 KRW · morning class 1,800,000 KRW
• Yonsei University Korean Language Institute 1,860,000 KRW

On top of that comes a non-refundable application fee: 70,000 KRW at Kyungpook National and Hannam, 80,000 KRW at Pusan National, and 120,000 KRW at Yonsei, so 70,000–120,000 KRW. Some schools charge insurance separately (Pusan National: 80,000 KRW per term), and some collect 4 terms of tuition at once when you first enroll (Kyungpook National). Degree program tuition is quoted per year rather than per term, so the two figures can't be compared as they stand (language school by term, degree program by year). According to the Ministry of Education and Korean Council for University Education's analysis of the April 2026 university information disclosure, average annual tuition per student at four-year general universities and universities of education is 7,270,300 KRW (private 8,231,500 KRW, national/public 4,250,000 KRW; capital region about 8,270,000 KRW, outside the capital region about 6,620,000 KRW). Converted to a year of 4 terms, language school comes to about 5,600,000 to 7,440,000 KRW, so the annual totals fall in an overlapping range.

Part-time work — where the two statuses differ the most

First, the premise. Profit-making and employment activities by international students and language trainees are prohibited in principle (Immigration Act Article 18(1) and Article 20). To work part-time, you must first obtain permission from the Minister of Justice to engage in activities outside your status of stay (a part-time work permit), and every hour figure below assumes you already have that permit. Working without a permit makes you subject to the penalty under Article 94, item 12, of the same Act (imprisonment of up to 3 years or a criminal fine of up to 30,000,000 KRW) and to deportation under Article 46(1), item 8, or a departure recommendation under Article 67(1), item 1. The imprisonment and fine figures are the statutory maximums in the provision; in practice, under version 2026-09-01 of the Ministry of Justice's Guide Manual for Residence Civil Affairs by Status, a first offense means a notice disposition followed by permission to stay if the violation is minor, and a second offense means deportation (see the step-by-step standards below).

The first wall you hit is the waiting period. Eligible are D-2-1 to D-2-4, D-2-6, and D-2-7 within Study Abroad (D-2) (the research track, D-2-5, is excluded); language trainees and short-term study (D-2-8) students can apply only after 6 months have passed from the date of change of status, or from the date of entry for visa holders (per the Ministry of Justice "Integrated Guide Manual by Status of Stay" of August 7, 2026, as cited by the Ministry of Government Legislation's Easy-to-Find Practical Law service).

The most important row is weekends, public holidays, and vacations. For D-2, once you meet the Korean requirement, there's no hour limit on weekends, public holidays, and vacations on top of the weekday limit, but that exception doesn't exist for D-4. The plan of earning a lot during vacation to pay for next term's fees simply doesn't work. Even on D-2, if you haven't met the Korean requirement, your limit is 10 hours a week including vacations (15 hours for master's/doctoral). The detailed requirements for the preferential hours aren't shown in the table, so check with your university's international office.

For D-2, the allowed weekly hours have depended on Korean ability under the standard in effect since July 2023. The benchmark is TOPIK Level 3 for associate-degree students and bachelor's students in years 1–2, and TOPIK Level 4 for bachelor's students in years 3–4 and master's/doctoral students. For language trainees (D-4), the benchmark is TOPIK Level 2, or completing Level 2 of the Social Integration Program (KIIP) or scoring 41 or higher on its pre-assessment, among others. The equivalence table in the Ministry of Education's Standard Procedures (amended March 27, 2026) shows how KIIP or King Sejong Institute completion can be recognized in place of TOPIK.

• TOPIK Level 2 = pre-assessment score of 41 or higher · completion of KIIP Level 2 · completion of King Sejong Institute Beginner 2
• TOPIK Level 3 = pre-assessment score of 61 or higher · completion of KIIP Level 3 · completion of King Sejong Institute Intermediate 1
• TOPIK Level 4 = pre-assessment score of 81 or higher · completion of KIIP Level 4 · completion of King Sejong Institute Intermediate 2
• For the King Sejong Institute, only a certificate of completion of the basic curriculum issued by a local King Sejong Institute is accepted; certificates from the Online King Sejong Institute are excluded (taking an overseas King Sejong Institute course online while staying in Korea doesn't count either).

However, the part-time work table in the National Institute for International Education (NIIED)'s "2026 Study in Korea Guidebook" lists the King Sejong Institute standard for language trainees differently from this equivalence table. If you want to use King Sejong Institute completion for a part-time work permit, check with your language school or HiKorea first. For KIIP applications and level placement, see How to Apply for KIIP, Korea's Social Integration Program. How the validity period of TOPIK scores is treated is judged separately in the part-time work review and in university admission review, so don't mix the two contexts.

There are industry restrictions too. Restricted are activities in professional fields (E-1 to E-7); manufacturing and construction under Non-professional Employment (E-9) and the industries covered by Vessel Crew Employment (E-10); special-type employment (courier drivers, delivery-agency riders, designated drivers, insurance agents, home-visit study-material teachers, door-to-door salespeople, and so on); employment through dispatch, subcontracting, or brokerage arrangements; and long-distance work (원거리 근무). As an exception, manufacturing is allowed if your Korean language ability is Level 4 or higher. The publicly available materials we checked (the Ministry of Government Legislation's Easy-to-Find Practical Law service and the 2018 public version of the Ministry of Justice guidelines) don't define what distance counts as "long-distance work" (원거리 근무), so check with your university's international office or ☎1345.

The penalties escalate heavily, too. Under version 2026-09-01 of the Ministry of Justice's Guide Manual for Residence Civil Affairs by Status, working without a permit means a notice disposition followed by permission to stay the first time you're caught if the violation is minor, and deportation the second time, and the departure order is attached only to illegal work in the construction sector (Yonsei University's international office describes the same point as paying a summary fine plus a 1-year permit restriction on the first offense, deportation without exception on the second, and departure within 30 days in construction and manufacturing regardless of how many times you've been caught, but that "1 year" is wording from the public version (2018) of the Ministry of Justice's "Guidelines on Visa Issuance and Stay Management for International Students" and is not in the current manual, and what blocks a new application under the current manual is not a penalty but a separate restriction ground, namely a record of having worked without a permit or violated permit conditions and been punished for it within the 3 months before the application date). If you did have a permit but violated its conditions, the section on standards for handling part-time work permit violations in that same manual sets a severe warning (1st), no part-time work for the rest of your study period (2nd), and cancellation of your student status (3rd) (Yonsei's guidance puts the first offense at no permit for 1 year, which is also 2018 guideline wording). And that same Yonsei guidance says violators are also restricted from the Job Seeking (D-10) status after graduation. We cover application documents and working conditions in the student part-time work permit guide.

Attendance splits into three numbers — where students who only attend language school get stuck

This is where language school students get confused most often. There isn't one attendance standard but three, and each is used for a different purpose. This is how you end up hearing "you've moved up a level" from your school and still not getting a part-time work permit.

The highest bar is the part-time work permit. Even if you clear the promotion standard (80% in the example), you won't get the permit unless you reach 90%. Conversely, if you look only at extensions, 70% is the dividing line, so a common sequence is thinking "my extension went through, so I'm fine" and then getting stuck at the part-time work permit. If you are at exactly 70%, you fall under both sentences in the guidelines at once. The same document writes the condition for granting the maximum (6 months) as "an attendance rate of 70% or higher" and the condition for restricting an extension as "an attendance rate of 70% or lower," putting the boundary value of 70% on both sides. The two provisions don't rule each other out, so even if you submit a written explanation and get the six-month extension, that term can still count toward the "two or more consecutive terms at 70% or lower" restriction. The final call is for the regional immigration office with jurisdiction to make, so if you are near 70%, check in advance with your university's international office and ☎1345. The two extension numbers are based on the 2018 public version of the Ministry of Justice guidelines, and for the 50% line the guidelines state their reasoning: at 4 hours a day for 20 weeks, it means not having attended even 200 of the 400 total class hours.

"I'll take a term off and come back" isn't an easy choice either. The guidelines (2018 public version) restrict extensions of stay for people who have stopped studying (taken a leave of absence) for personal reasons, insufficient credits, or the like (leave of absence for family reasons isn't accepted). Only when an unavoidable reason such as illness or an accident is recognized can a change to another status of stay be allowed as an exception. Because taking a term off after running out of money turns straight into a residence problem, you need to plan your finances for tuition over a longer horizon.

The school reports these numbers through the International Student Information System (FIMS). Credits and grades are reported only for degree students, twice a year (end of February and end of August); attendance is reported only for language trainees, within 15 days after the course ends. It's safest to assume your language school attendance record is passed on even if you don't submit it yourself.

Three paths from D-4 to D-2

Under the Ministry of Education's Standard Procedures (amended March 27, 2026), there are three paths from a language school up to an undergraduate program. All of them are recommended standards for universities, so universities can set higher or different requirements, and the final word is the admission guide of the university you're applying to.

1. Getting a TOPIK level — The recommended standard is entering a four-year university or graduate school with TOPIK Level 3 or higher and obtaining Level 4 or higher before graduation, or entering a junior college or associate degree program with Level 2 or higher and obtaining Level 3 or higher before graduation.
2. Completing 1 year or more of language training at the same university — Even without a TOPIK level, if you complete (finish) 1 year or more of Korean language training at the same university's language training institute in Korea and pass the school's assessment at the corresponding level, you can be recognized as meeting the admission requirement (Level 3 equivalent for four-year universities, Level 2 equivalent for junior colleges).
3. Conditional admission with TOPIK Level 2 — If a four-year university admits TOPIK Level 2 holders, it must require them to complete 300 hours or more of Korean language training within 1 year after admission (the same university's language training program, or a KIIP or King Sejong Institute Korean course). If the student obtains TOPIK Level 3 during the first semester, this drops to 120 hours.

What matters in practice is the "same university" condition in path 2. If you finish D-4 at a university and apply to change to D-2 for that same university's degree program, the financial-capacity screening standard is eased by up to half (per the 2018 public version of the Ministry of Justice guidelines). In that case, however, proof of finances is in principle accepted only as a bank balance certificate in your own name issued by a bank in Korea. What separates the two benefits isn't the region but whether it's the same school. If you study at a cheaper language school and then apply to a different university, you lose both the TOPIK substitute recognition and the financial easing even within the same region, so weigh your final target university at the stage of choosing a language school. When you apply for the change, you have to submit a grade (attendance/training) certificate from your previous program (only if it can't be verified in FIMS, per the 2018 public version of the guidelines). That means your language school attendance record carries over as review material for undergraduate admission.

There are also restrictions depending on how you entered. The Ministry of Justice guidelines (2018 public version) include short-term visitors who entered on tourist/transit status or under a visa waiver among those who can change to D-2 or D-4 inside Korea, but attach restrictions. For nationals of countries designated by public notice of the Minister of Justice, a change is allowed only as an exception and only to a certified university, and for language training (D-4), even this exception excludes holders of B-2, C-3-2, C-3-3, and C-3-9. For nationals of other countries, the change is restricted for pure/group tourism (C-3-2), medical tourism (C-3-3), and general tourism (C-3-9) statuses, and it's also restricted for D-3, E-9, E-10, and G-1 holders registered in Korea (G-1-6 humanitarian stay permit holders are excluded from this restriction). The outcome depends on your nationality and entry status, and this provision may have changed since, so if you want to change your status inside Korea, check with ☎1345 and the university's international office before you apply.

The fees under Article 72 of the Enforcement Rules of the Immigration Act are 100,000 KRW for a change of status of stay, 60,000 KRW for an extension of stay, and 35,000 KRW for issuance or reissuance of an Alien Registration Card. Permission to engage in activities outside your status of stay costs 120,000 KRW, but it's 20,000 KRW in cases the Minister of Justice recognizes, such as part-time work by Study Abroad (D-2) or General Training (D-4) holders. However, the list of application documents for part-time work in the Ministry of Justice guidelines (2018 public version) says "fee (waived)," and Government24 and some universities' notices also say it's waived if you submit a confirmation issued by the university, so these conflict with the wording of the Rules and you'll need to check. Don't forget alien registration either. If you intend to stay more than 90 days from your date of entry, you must register within 90 days, and a person who receives a change-of-status permit and will thereby stay more than 90 days registers at the time they receive the change permit (Immigration Act Article 31). The procedures are in How to Apply for an Alien Registration Card and How to Change Your Visa Status and Required Documents. We couldn't confirm the standard processing time for changing from D-4 to D-2, so ask the immigration office with jurisdiction and your school's international office; for the online application flow, see How to File a Hi Korea e-Application.

If the school doesn't act, nothing starts

This is the core of this article. Being accepted by a language school and paying tuition doesn't by itself start your D-4. The Standard Certificate of Admission (표준입학허가서) needed for a visa, a Certificate for Confirmation of Visa Issuance, or a change of status of stay is in principle verified through the International Student Information System (FIMS). An admission number is generated only once the school's staff registers it, and once it's generated, even the school's staff can't edit it. There's practically no step a student can push through alone. Once you've received your acceptance notice, the next thing to check isn't your tuition payment date but the issuance schedule for your Standard Certificate of Admission.

The school also has reporting obligations. Article 19-4 of the Immigration Act requires the head of a school to designate a staff member in charge of managing international students and report who it is, and to report within 15 days when an international student fails to register by the registration deadline each semester or takes a leave of absence, or when their study or training has ended due to expulsion, discontinuation of training, disappearance, and so on. Violating this carries an administrative fine of up to 2,000,000 KRW under Article 100(1), item 2, of the same Act. Schools have no incentive to delay reporting, so it's fair to assume the route of quietly dropping out and sorting it out later is closed.

The school's rating also directly affects your visa. According to a joint Ministry of Justice–Ministry of Education press release (February 12, 2026), the universities certified in 2025 under the International Education Quality Assurance System (교육국제화역량 인증제) number 181 for degree programs (including 39 excellent certified universities; 158 the previous year) and 123 for language training programs (103 the previous year). Certification lasts 4 years (March 2026 to February 2030), but schools are monitored every year and certification is revoked if they fall short of the standards. These numbers are from the February 2026 announcement (2025 evaluation), so check the latest list on Study in Korea (www.studyinkorea.go.kr).

• If it's a certified university, the visa review is simplified to a process that screens on the Standard Certificate of Admission alone. However, nationals of countries designated by public notice of the Minister of Justice and of countries under intensive management must submit proof of financial capacity even at a certified university (at the 39 excellent certified universities, the review is simplified without that exception).
• There's a flip side, too. Universities that fall short of the on-site survey standards are designated as universities under strengthened visa screening (비자심사 강화대학), and there are two types. Consulting universities (컨설팅대학, 13 in 2025) are subject to close review, such as interviews or on-site surveys on academic qualifications, financial capacity, and the likelihood of illegal employment, while universities under intensive visa review (비자정밀 심사대학; 16 for degree programs, 4 for language training programs) face restricted visa issuance for 1 year starting from the second semester of 2026 (per the table in the announcement: "visa issuance prohibited in principle"). No matter how diligent a student is, if the school is designated a university under intensive visa review, the visa won't be issued. The lists of general universities and consulting universities aren't made public.

For reference, the 2018 guidelines restricted visa issuance (including confirmations of visa issuance), status changes, and transfers for what were then called "recruitment-restricted (visa-restricted) universities," while excluding doctoral, research, and exchange students (D-2-4 to D-2-6) from the restriction. We couldn't confirm whether this exception also applies to the current universities under intensive visa review, because the February 2026 announcement doesn't mention it.

The criterion that separates the ratings is the illegal-stay rate. The basic requirements for certification are below 1% for degree programs at universities with 1,000 or more enrolled international students and below 2% at those with fewer than 1,000, and below 8–12% for language training programs; if the on-site survey finds 5% or more for degree programs or 20% or more for language training programs, the university is designated as a university under strengthened visa screening (a consulting university or a university under intensive visa review). The same materials also contain quality indicators you can use when choosing a language school. The certification indicators for language training programs are a Korean language teacher certificate rate of 90% or higher, fewer than 20 language trainees per class, a tuition burden ratio of 80% or higher, a completion rate of 50% or higher for courses under 1 year, and a TOPIK Level 2 attainment rate of 30% or higher for courses of 1 year or more; the core indicators for universities under strengthened visa screening include 30 or more students per class, a teacher certificate rate below 80%, and a completion rate below 30%. However, the announcement doesn't say which value between 8% and 12% applies to a given language training program, or what the "tuition burden ratio" is a ratio of. You can ask the language institute directly about class size and the teacher certificate rate, so add them to your list of questions for your consultation.

Documents can also differ by nationality. The guidelines (2018 public version) impose additional steps on nationals of countries designated by public notice of the Minister of Justice (21 countries at the time), such as notarization of diplomas, a detailed review of financial capacity, and a substantive review of the need for language training. The public notice gets revised, so we haven't copied the list of countries here. Just know that not everyone is asked for the same documents, and check whether your nationality is covered with a Korean embassy or consulate abroad or with 1345.

What to check yourself before you apply

If you get the order wrong, the money goes out first and the checking comes later.

• ① Whether your program is D-2 or D-4 — it depends on whether it's a regular degree program or a university-affiliated language institute program.
• ② Whether the language institute is run directly by the university or by an outside operator — visa issuance may not be possible for institutes run by an outside operator.
• ③ Whether the school is a certified university, or a university under strengthened visa screening (consulting university or university under intensive visa review) — check on Study in Korea (www.studyinkorea.go.kr) and the National Research Foundation of Korea (www.nrf.re.kr); the numbers in this article are from the 2025 evaluation.
• ④ The issuance schedule for your Standard Certificate of Admission — this date, not your tuition payment date, is the starting point of your visa timeline.
• ⑤ The financial-capacity standard and the issue date of your bank balance certificate — as a rule, it must be issued within 30 days before the application date.
• ⑥ Whether your final target university and your language school are the same school — if they are, you can be eligible for both the TOPIK substitute recognition and the up-to-half easing of the financial requirement.
• ⑦ When your part-time work plans can start — for language trainees, the requirements are 6 months elapsed and an average attendance rate of 90% or higher across all completed terms.

Here's what we couldn't confirm. The full text of the Ministry of Justice guidelines we could publicly confirm is the public version fully revised March 1, 2018, so whether the 70% and 50% attendance standards, the 2-year maximum for language training, the up-to-half easing of the financial requirement, and the status-change restrictions for short-term visitors still have the same wording today is unconfirmed. The current weekly hours allowed for language trainees are values we cross-checked against the table in NIIED's "2026 Study in Korea Guidebook" and university notices, because the Study (D-2) table in version 2026-09-01 of the Ministry of Justice's Guide Manual for Residence Civil Affairs by Status has no row for language training. For the part-time work permit fee we checked both the wording of the Enforcement Rules (20,000 KRW) and the Ministry of Justice guidelines and practical notices (waived), but we couldn't confirm which one actually applies now or which provision the waiver rests on. We also couldn't confirm the current lists of designated and intensive-management countries, the names of the universities under intensive visa review, the scope of the capital region in the financial-capacity standard, or the rules for switching between language schools, so we've left those blank. Please check with ☎1345, HiKorea, and the international office of the university you're applying to.

Frequently Asked Questions (FAQ)

Q1. I got into a language school and even paid tuition. Why hasn't my visa application started? A. The Standard Certificate of Admission is in principle verified through the International Student Information System (FIMS). An admission number is generated only once the school's staff registers it, and once it's generated, even the school's staff can't edit it. Paying tuition and starting your visa application are separate things, so after you're accepted, check the issuance schedule with your school first. You also need to confirm whether the language institute is run directly by the university. The Ministry of Education's Standard Procedures (amended March 27, 2026) state explicitly that for institutes run by an outside operator, visa issuance may not be possible under the Ministry of Justice guidelines.

Q2. So D-4 students can't work part-time at all? A. That's not the case. Language trainees (D-4-1, D-4-7) can apply for a part-time work permit only after 6 months have passed from the date of change of status, or from the date of entry for visa holders, and they need an average attendance rate of 90% or higher across all completed terms. Once you have the permit, you can work up to 20 hours a week if you meet the Korean requirement (TOPIK Level 2, or completing KIIP Level 2 or scoring 41 or higher on the pre-assessment, among others), or 25 hours for those who qualify through a certified university, top grades, or excellent Korean, and up to 10 hours a week if you don't meet it. You're limited to 1 workplace, and each permit lasts up to 6 months. The no-hour-limit rule for weekends, public holidays, and vacations that applies to degree programs doesn't exist for D-4. Working without a permit can be punished under Immigration Act Article 94, item 12, with imprisonment of up to 3 years or a criminal fine of up to 30,000,000 KRW; that's the statutory maximum in the provision, and in practice, under version 2026-09-01 of the Ministry of Justice's Guide Manual for Residence Civil Affairs by Status, a first offense means a notice disposition followed by permission to stay if the violation is minor and a second offense means deportation.

Q3. My language school attendance is 75%, and the school says I've moved up a level. Will I get a part-time work permit too? A. There are three separate standards. The school promotion standard follows school rules (e.g., Kyungpook National requires attendance of 80% or higher and an overall score of 70 or higher); under the extension of stay standard, at or below 70% you're extended once only with a written statement of reasons, and extensions are restricted if it happens twice or more in a row (2018 public version of the Ministry of Justice guidelines); and the part-time work permit standard is an average of 90% or higher across all completed terms. The part-time work permit has the highest bar, so even if you've moved up a level, your application may be blocked if you haven't reached 90%. Check your own figures with the language institute's office and your school's international office.

Q4. I don't have a TOPIK level. Can I get into an undergraduate program by attending a language school? A. There is a path, but admission isn't guaranteed. The Ministry of Education's Standard Procedures (amended March 27, 2026) provide that even without a TOPIK level, if you complete (finish) 1 year or more of Korean language training at the same university's language training institute in Korea and pass the school's assessment at the corresponding level, you can be recognized as meeting the admission requirement (Level 3 equivalent for four-year universities, Level 2 equivalent for junior colleges). If a four-year university admits TOPIK Level 2 holders, they must complete 300 hours or more of Korean language training within 1 year after admission, reduced to 120 hours if they obtain Level 3 during the first semester. However, these standards are recommendations, and actual admission requirements are set by each university on its own, so check the admission guide of the university you're applying to.

Q5. How much does language school cost? Is having the visa bank balance enough? A. The two numbers are separate. The financial-capacity standard is 10,000,000 KRW or more in the capital region and 8,000,000 KRW or more outside it for language training programs, and 20,000,000 KRW or more per year in the capital region and 16,000,000 KRW or more per year outside it for degree programs (per the Ministry of Education's Standard Procedures, amended March 27, 2026; if your university is in Incheon or Gyeonggi, ask its international office which standard applies). Actual school fees are paid separately. Based on 6 schools' notices, language school fees are about 1,400,000–1,860,000 KRW per term (usually 10 weeks), and some schools add a non-refundable application fee of 70,000–120,000 KRW plus insurance, while others collect 4 terms of tuition at once when you first enroll. Costs vary a lot by school, so check the official information of the university you're applying to directly.
