D-3 Industrial Trainee Visa Korea — Technical Training, Eligibility & Sponsorship Rules
The (기술연수) visa allows foreign nationals to receive industrial and technical training at Korean manufacturing companies. Unlike (the employment visa for non-professional workers), D-3 is a training visa — the legal framework positions the trainee as learning Korean production methods to later apply at their home-country employer.

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.
Who qualifies and what is D-3 used for?
is used for two main scenarios:
1. Corporate group training (계열사 연수):
A foreign employee of an overseas subsidiary or affiliate of a Korean conglomerate comes to the Korean parent company for technical skills training. Common in Samsung, Hyundai, LG, and similar groups with overseas manufacturing operations.
2. ODA/KOICA technical cooperation training:
Foreign nationals from developing countries sponsored under Korea's ODA programs receive industrial training at Korean companies.
The D-3 framework requires:
• A Korean company approved as a training institution (연수기관)
• A formal training plan (연수계획서)
• The trainee must have a genuine connection to an overseas entity
• The training must be time-limited and oriented toward skills transfer back to the home country
Stay duration, conditions, and D-3 vs E-9
Duration: is issued for up to 1 year, renewable up to a total of 2 years.
Conditions: trainees receive a training allowance (연수수당), not a salary. They do not have full employment law protections and cannot freely change companies.

Tips from 행정사s
