The D-4-6 (우수사설교육기관 외국인연수) visa is for foreign nationals attending approved private vocational or specialized educational institutions in Korea. It bridges the gap between the general language school D-4-1 visa and the university-level student visa, covering professional and skills-based training programs at accredited private academies. If you are planning to attend a cooking school, beauty school, K-pop dance academy, film production program, or similar specialized vocational program lasting several months to a few years, D-4-6 is likely your visa category.

Filing caution
Requirements can change by nationality, local immigration office, and filing channel. Confirm exact requirements with HiKorea, the responsible Korean consulate, or a licensed immigration specialist before filing.
D-4-6 is the 'outstanding private educational institution foreign trainee' visa. The key differences from other D-4 subtypes:
D-4-6 covers training programs at private academies (학원) licensed under Korea's Academy Establishment and Operation Act, specifically in vocational skills fields (직업기술 분야 평생직업교육학원). The program must be more than just a one-time or short-duration workshop — ongoing multi-month training programs are what the visa is designed for.
Not all private academies qualify. The institution must be a 'vocational skills lifelong vocational education academy' (직업기술 분야 평생직업교육학원) as defined under Korea's Lifelong Education Act and Academy Act. In practice, this includes:
Note: even if a program is nominally vocational, D-4-6 is NOT issued for one-time courses or short workshops. The training program must be a structured, multi-month curriculum at a designated institution. Programs that run for 20 months or more and result in an officially recognized domestic qualification certificate may provide a pathway to employment.
The standard D-4-6 initial grant is up to 1 year, renewable. The residency manual's stay cost standard for D-4-6 trainees follows the same benchmark as D-4-1 language students (the current figure is approximately KRW 3.5–4.5 million per year in demonstrable financial resources, though exact amounts vary).
For D-4-6 extension applications, submit: the standard immigration application form, passport, alien registration card, proof of enrollment at the qualifying institution, proof of financial sufficiency, and any institution-specific forms required by the academy.
D-4-6 trainees in vocational programs may participate in on-site practical training (현장실습 / field practicum) as part of their curriculum. The rules governing this practicum are formal and contractual:
This structure is important: D-4-6 holders cannot independently work in Korea outside the scope of their training curriculum. Unauthorized work is a status violation.
One of the most valuable features of D-4-6 is its formal pathway to (Specialty Occupation) employment. Trainees who complete a 20-month-or-longer D-4-6 program and obtain a recognized domestic qualification certificate (국내 공인 자격증) are eligible to apply for E-7 status.
The practical pathway:
This makes D-4-6 particularly valuable for those who want a structured entry pathway into Korea's skilled labor market without a pre-existing degree or job offer.
D-4-6 visas are applied for at a Korean embassy or consulate in your home country. You will need:
The consulate will verify that the institution is a qualifying vocational academy under the residency manual's D-4-6 criteria. Not all academies that call themselves 'vocational' meet the formal criteria — confirm with the institution before applying that they are designated for D-4-6 trainee enrollment.

Visa Process
Alien Registration Card (ARC)
The Alien Registration Card (ARC) is the official ID card issued to foreigners staying in South Korea for 91 days or longer. It is required to open a bank account, sign a phone contract, and access most public services.

How to use HiKorea (www.hikorea.go.kr) — Korea's official immigration portal for visa extensions, status changes, and ARC renewal. Processing time: 3-10 business days.
Visa Process
Visa Extension (Stay Period Extension)
A visa extension — officially called a 'stay period extension' (체류기간 연장) in Korean immigration law — allows a foreigner to legally remain in Korea beyond the expiry date on their current visa or ARC without leaving the country.
Visa Process
Status of Sojourn Change (체류자격 변경)
A status of sojourn change allows a foreigner already in South Korea to switch from one visa category to another without leaving the country — for example, from a D-2 student visa to an E-7 skilled worker visa upon graduation and employment.
Can I attend a K-pop idol training academy on a D-4-6 visa?
Yes, if the academy is a formally licensed private vocational institution (학원) in the performing arts field and offers a structured training curriculum. However, performing publicly or receiving payment for performances would require a different status (E-6). D-4-6 is for the training/education phase only.
My D-4-6 program is only 3 months. Will I get the visa?
D-4-6 is not issued for one-time or short-term workshops. While there is no hard statutory minimum duration in all cases, programs of only 3 months are generally too short to meet the 'structured vocational training program' intent of the visa. Consulates apply discretion. Programs of 6 months or more at a recognized institution have a much stronger application profile.
What is the difference between D-4-6 and the D-4-2K corporate internship visa?
D-4-6 is for self-enrolled foreign trainees attending a private vocational institution independently. D-4-2K is a corporate internship track where a Korean company brings in foreign workers from specific sending countries (Vietnam, China, Thailand, etc.) as corporate-sponsored interns through a verified internship (CVI) process. D-4-2K is company-sponsored; D-4-6 is institution-enrolled.
I finished my D-4-6 program and got a qualification certificate. How long does the E-7 change take?
Status changes from D-4-6 to E-7 follow the standard E-7 change-of-status process. At the time of this guide's publication, E-7 applications typically take 4–12 weeks depending on the occupation, employer type, and current immigration workload. Apply before your D-4-6 status expires.
