D-3 to E-7: Can Industrial Trainees Get a Work Visa in Korea?
Korea's D-3 (Industrial Trainee / 기술연수) visa allows foreign workers from developing countries to train at Korean companies as part of international development cooperation programs. But what happens if you want to stay in Korea and work after your training ends? The residency manual's rule is that D-3 holders cannot change status inside Korea, and it lists D-3 among the statuses restricted from changing to E-7. This guide explains that rule, the provision it is often confused with, and the routes that remain.

What is the D-3 Industrial Trainee visa?
The D-3 visa is not a regular work permit. It is a structured industrial training program where a foreign national from a sending country organization comes to Korea to receive technical training at a Korean company. Key features:
- The trainee is affiliated with an overseas organization (typically a state-run technical training agency or approved sending organization) that has an agreement with a Korean company or industrial association
- The trainee is not treated as a Korean employee — they are a trainee receiving a training stipend, not a salary
- The Korean training company is responsible for the trainee's welfare and training curriculum
- D-3 is available to nationals of developing countries that have bilateral technical cooperation agreements with Korea
- Training is in principle limited to 6 months from the date of entry and can be extended up to a maximum of 2 years from entry
Korean language education — a D-4-6 rule often attributed to D-3
These rules are often attributed to D-3, but in the residency manual they sit in the section on excellent private training institutes (D-4-6), not in the D-3 chapter:
- D-4-6 institutions guide their trainees on how to join the Social Integration Program (KIIP), so that trainees can meet the requirements for changing to E-7
- They may run Korean language classes for their own enrolled trainees, taught by certified Korean language instructors; charging extra tuition for these classes is strictly prohibited
- Korean language classes do not count toward the required technical training hours (15 hours or more per week)
The D-3 chapter states that D-3 holders cannot change status in principle.
D-3 to E-7: in-country status change is restricted
The residency manual does not provide a D-3 to E-7 conversion. Its D-3 chapter states that change of status is not allowed in principle (체류자격 변경 불가 원칙), and its E-7 chapter lists industrial training (D-3) among the statuses restricted from changing to E-7, together with short-term statuses (B and C series), E-8, E-9, E-10 and G-1.
The conditions often quoted for this route — KIIP Stage 4 or above and the exclusion of E-7-4 — belong to a different provision: the employment special case for graduates of excellent private training institutes (D-4-6). That provision allows a change to E-7 in the field of study for holders of an overseas associate degree or higher who complete a D-4-6 course of 20 months or more in that field, obtain a Korean nationally recognised certificate and complete KIIP Stage 4 or above. E-7-4 is excluded from it.
The route that remains for a D-3 trainee is to leave Korea at the end of training and apply for an E-7 from abroad: the employer applies for a visa issuance confirmation (사증발급인정서) at the immigration office covering its address, and the applicant must meet the education, experience and salary requirements of the E-7 occupation like any other applicant.
D-3 sending country framework and quota system
D-3 trainees come through approved sending organizations in their home countries that have MOU agreements with Korean industrial associations or companies. The sending country framework is government-managed:
- Sending countries include many in Asia, Africa, and Latin America that have bilateral technical cooperation MOUs with Korea
- Each company's quota of D-3 trainees is based on their size and previous training track record
- Companies that have successfully trained D-3 trainees and facilitated their transition to stable employment have stronger track records for future quota requests
Trainees do not apply for D-3 independently — the Korean company and the sending country organization jointly process the entry.
Alternative pathways if D-3 to E-7 is not possible
If a D-3 trainee does not meet E-7 requirements (e.g., doesn't have the required degree or the job offer doesn't match the E-7 criteria), other options include:
- D-4-6 then E-7: D-3 holders are restricted from changing to D-4-6 inside Korea, so this means leaving and re-entering on a D-4-6 visa. With an overseas associate degree or higher, complete a course of 20 months or more in your field at an approved technical training institute, obtain a Korean nationally recognised certificate, complete KIIP Stage 4 or above, and then apply to change to E-7 in that field
- D-10-1 job seeker: If you have a relevant bachelor's degree and meet the points requirements, apply for D-10-1 to seek employment while staying in Korea
- Depart and apply from home country: If no in-country pathway works, the E-7 application can be initiated from your home country consulate once you have a job offer and the required qualifications

Visa Process
Alien Registration Card (ARC)

Visa Process
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.
Frequently asked questions
I completed my D-3 training and my Korean company wants to hire me full-time. How do I change to E-7?
Under the residency manual you generally cannot do this inside Korea: D-3 holders are restricted from changing to E-7, and the D-3 chapter says change of status is not allowed in principle. The usual route is to leave at the end of training and have the company apply for a visa issuance confirmation (사증발급인정서) for an E-7 occupation whose education, experience and salary requirements you meet. Ask your immigration office before your D-3 expires whether any exception applies to your case.
Can D-3 holders change to E-9?
No. D-3 industrial trainees cannot change status to E-9 (unskilled worker permit) — the residency manual explicitly lists D-3 as one of the statuses not eligible for change to E-9. The manual likewise lists D-3 among the statuses restricted from changing to E-7 inside Korea.
My D-3 training ended but I don't have a job offer yet. Can I get a D-10 job seeker visa?
Potentially yes, if you meet the D-10-1 points requirements (bachelor's degree + 60 points). However, D-3 alone does not exempt you from the points test. You need to calculate your D-10-1 score based on age, education, work experience, Korean study, and Korean language ability.
