D-2 vs D-4 Visa — Degree Student or Language Learner?

and are both study visas, but they serve different purposes. The D-2 is for degree-seeking students enrolled in a full bachelor's, master's, or doctoral program at an accredited Korean university. The D-4 is for general training — most commonly Korean language study at a university-affiliated language institute (어학당). Many students start on D-4 to build their Korean proficiency, then transfer to D-2 once admitted to a degree program.

자주 묻는 질문

Can I work while on a D-4 visa?

Yes — but only up to 20 hours per week, and you must obtain prior work authorization (사전취업허가) from the immigration office. You cannot start working before getting this permit. Violation can result in visa cancellation.

Can I change from D-4 to D-2 without leaving Korea?

Yes. Once you receive an admission letter from a Korean university degree program, you can apply for a status change at your local immigration office. You do not need to return home.

How long can I stay on a D-4 visa?

D-4 is typically granted for the length of your course enrollment, up to 1 year per grant. Extensions are possible if you enroll in further courses. The total maximum stay on D-4 is generally 2 years for language training.

Does D-2 study count toward the F-2-7 K-Point score?

Graduating from a Korean university (bachelor's or higher) adds bonus points to your K-Point score for F-2-7. A Korean university bachelor's degree adds 10–15 bonus points, which can be decisive in reaching the 80-point threshold.

Can I study Korean at a private academy (학원) on a tourist visa?

Short language courses at private academies are possible on C-3 tourist status, but this is limited to 90 days and is not a replacement for D-4. For structured long-term language study at a university language institute, D-4 is the correct status.
