What is the difference between a D-2 visa and a D-4 visa?
This FAQ summarizes the differences between the D-2 (Student) and D-4 (General Training) visas required for studying in Korea, as well as how to switch between them and the scope of permitted activities.
Key Points
- The core difference is the purpose of study: the D-2 is for degree programs (undergraduate, associate's, master's, doctoral, and research), while the D-4 is for language schools and other training institutions.
- D-2 holders may work part-time up to 20 hours per week with approval from the Immigration Office, whereas D-4 holders are generally not permitted to work except in limited cases.
- The D-2 stay covers the length of the degree program and can be extended by up to 2 more years, while the D-4 typically allows a stay of up to about 2 years.
- Students on a D-4 can apply to change their status to a D-2 once they receive an admission offer to a degree program, a common route after completing Korean-language study.
The D-2 vs D-4 visa decision starts with your study purpose. Degree students normally check the D-2 route, while Korean language or non-degree training students start with D-4. This FAQ uses Study in Korea visa guidance to compare purpose, documents, stay planning, part-time work checks, and when a D-4 to D-2 transition becomes relevant.
The key difference between the two visas lies in the purpose of study.
