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 D-2 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.
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 E-7 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 E-7 (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.

Find a SpecialistCan 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.
