D-2 vs D-4: Which Korean Student Visa Do You Need?
D-2 vs D-4 visa compared: degree vs language study, who each is for, what you can do, and how to switch from a D-4 to a D-2 in Korea.
Choosing between a D-2 vs D-4 visa comes down to one question: are you enrolling in a degree, or are you studying Korean / a non-degree course first? This guide compares the two so you pick the right one — and shows how to move from a D-4 to a D-2 later.
Unsure which fits your plan? Ask a consultant.
The core difference
- D-2 — degree programs (associate, bachelor's, master's, PhD) at accredited universities.
- D-4 — non-degree study, mainly university language institutes (한국어학당) and similar courses.
Side-by-side
| D-2 (degree) | D-4 (language / non-degree) | |
|---|---|---|
| Purpose | Full degree | Language / short courses |
| Typical students | Undergrads, grad students | Language learners, pre-degree |
| Part-time work | Allowed with permit | Allowed with permit (stricter) |
| Path forward | Toward graduation → work visa | Often → D-2 |
Which should you choose?
- Enrolling in a degree now? → D-2.
- Want to learn Korean first, then start a degree? → D-4, then switch to D-2.
- Not admitted yet but want to be in Korea studying the language? → D-4.
Switching from D-4 to D-2
Once you're admitted to a degree program, you can usually change status to a D-2 at an immigration office without leaving Korea. Line up your admission documents and updated proof of funds, and apply before your D-4 expires. Book the appointment on HiKorea in advance.
