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.
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 residency manual explicitly requires D-3 training institutions to:
This requirement exists partly to help trainees who later want to change status to long-term visas, which increasingly require Korean language ability.
The residency manual has a specific provision allowing D-3 trainees to change to E-7 (Specially Designated Activities) status under these conditions:
Eligibility:
Process:
Important limitation: The → pathway is specifically for E-7 professional and quasi-professional categories (E-7-1, E-7-2, E-7-3). It does NOT apply to E-7-4 (semi-skilled points track).
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:
Trainees do not apply for independently — the Korean company and the sending country organization jointly process the entry.
If a trainee does not meet requirements (e.g., doesn't have the required degree or the job offer doesn't match the E-7 criteria), other options include:

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.
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.
I completed my D-3 training and my Korean company wants to hire me full-time. How do I change to E-7?
Confirm that the job role matches an E-7 permitted occupation code and that you meet the educational/qualification requirements for that code. Then apply for status change at your local immigration office with: your application form, passport, ARC, employment contract, employer's business registration, your degree certificate, and any other occupation-specific documents. Also confirm that your salary meets the E-7 GNI threshold.
Can D-3 holders change to E-9?
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.
