The -2K (K-Trainee) visa was established in October 2025 as a new sub-category of the D-4 training visa framework. It is specifically for employees of Korean companies' overseas subsidiaries in 9 designated countries who come to Korea to intern at the Korean headquarters or branch. D-4-2K is different from (industrial trainee) in that it targets white-collar and management-track employees, not factory-floor technical trainees.

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-4-2K is the 'K-Trainee' (케이-트레이니) corporate internship visa for foreign employees of Korean company overseas subsidiaries.
Target population: Employees of Korean conglomerates' overseas operations who:
• Are currently employed at an overseas subsidiary, affiliate, or joint venture of a Korean company
• Have been selected by their employer for an internship at the Korean headquarters or Korean branch
• Are coming to Korea specifically to develop skills, build corporate culture alignment, or receive management training
9 designated eligible countries (as of October 2025):
Nationals of countries not on this list are not eligible for D-4-2K. If the Korean company's subsidiary is in a country not on this list, the D-3 (industrial trainee) or C-3-4 (short-term training) route may be alternative options.
For the applicant:
• Must be an active employee of the qualifying overseas subsidiary (employment contract + salary proof required)
• The internship must be sponsored formally by the Korean headquarters — not a personal arrangement
• The internship must have a defined program and duration
For the Korean company:
• Must be a legally registered Korean company (법인)
• Must have an established overseas subsidiary, affiliate, or joint venture in one of the 9 eligible countries
• Must submit a formal internship program plan (인턴십 계획서) to the immigration authority via the 사증발급인정서 (Certificate of Visa Issuance) process
Stay duration: -2K is issued for the duration of the internship program, typically 3–12 months. It is not renewable for extended open-ended stay.
Work permission: Similar to , the -2K holder is in a training/internship status, not full employment. The Korean company cannot use D-4-2K interns as a substitute for regular Korean employees.
-2K uses the 사증발급인정서 (Certificate of Visa Issuance / CVI) application process — meaning the Korean headquarters applies on behalf of the intern from Korea, and the intern receives the CVI to take to the Korean embassy/consulate in their home country.
Process:
Key documents for the intern:
• Valid passport
• Visa application form + photo
• CVI reference number from the Korean headquarters
• Employment certificate from the overseas subsidiary (재직증명서)
• Internship acceptance letter from the Korean headquarters
| -2K K-Trainee | Industrial Trainee | |
|---|---|---|
| Target | White-collar/management interns | Factory/technical trainees |
| Established | October 2025 | Long-standing |
| Country restriction | 9 designated countries | Corporate group or ODA countries |
| Application route | CVI (headquarters applies) | CVI (company applies) |
| Duration | 3–12 months | Up to 2 years |
| Training type | Corporate management/skills | Industrial/manufacturing technology |
The CVI application is submitted by the Korean headquarters — as the intern, you should work with your company's HR team in Korea (or Korea headquarters) to initiate the process.
Check whether your country is on the 9-country list. If your country was recently added or the list has been updated, confirm with the Korean embassy in your country.

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.

HiKorea
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 convert from D-4-2K to a work visa after my internship?
D-4-2K does not automatically convert to an employment visa. After the internship, if you want to work in Korea, you must qualify for and apply for an E-7 (or other work visa) based on your own credentials and a job offer from a Korean company. The internship experience may help strengthen an E-7 application but does not guarantee it.
My company has a subsidiary in Australia, which is not on the 9-country list. What are the alternatives?
If your country is not on the D-4-2K eligible list, options include: D-3 (industrial trainee) for technical/manufacturing training under the corporate group framework, C-3-4 (short-term training up to 90 days), or D-7 (intracompany transfer) if you qualify as a manager/specialist being transferred to the Korean entity.
