D-2 vs D-4 Visa for Korea: Which One Do You Need?
Use the D-2 if you are enrolling in a degree (bachelor's, master's, PhD, or research). Use the D-4 if you are coming to study Korean at a university language institute. The D-2 is the degree visa; the D-4 is the language visa. Many students start on a D-4 and convert to a D-2 once they are admitted to a degree.
People mix these up constantly, and the wrong choice can cost you a semester. The distinction is simple at its core: the D-2 is for a degree, the D-4 is for a language course. But they differ on more than purpose, including how much you can work, how much money you must show, and how long you can stay. Here is the full comparison and how to move between them.
- D-2 is the degree visa. For associate, bachelor's, master's, PhD, and research programs at a university.
- D-4 is the language visa. For studying Korean at a university-affiliated language institute (the common subtype is D-4-1).
- Both require financial proof, but the D-4 threshold is lower than the D-2, because a language year costs less.
- Both allow limited part-time work, with a permit, and the limits depend on your level and Korean ability.
- You can convert a D-4 to a D-2 once a degree program admits you, often without leaving Korea, but your D-4 attendance record matters.
The comparison at a glance
| D-2 (student) | D-4 (language) | |
|---|---|---|
| For | Degree programs (bachelor's, master's, PhD, research) | Korean language institute study |
| Issued on | A Certificate of Admission to a degree program | Enrollment at a university language program |
| Typical length | The length of your degree, extended each year | Per term, up to a capped total for language study |
| Financial proof | Higher (around the degree-student threshold) | Lower than the D-2 |
| Part-time work | Allowed with a permit, hours by level and TOPIK | Allowed with a permit, after a waiting period, tighter limits |
| Leads to | Graduation, then work visas like D-10 and E-7 | A degree (convert to D-2) or further study |
For the full detail on each, see the dedicated D-2 student visa guide and the D-4 language visa guide.
Which one is right for you
- You have been admitted to a degree program. You need a D-2. The Certificate of Admission your university issues is the key document.
- You want to learn Korean first, then maybe apply for a degree. Start on a D-4 at a language institute. Many students do exactly this.
- You are a GKS scholar doing the funded language year before your degree. Your university and NIIED will tell you which visa to use for each stage.
- You are unsure you can meet a degree's Korean requirement yet. A language year on a D-4 is a legitimate route to the TOPIK level a degree needs.
Work rules: what each lets you do
Both visas allow part-time work, but only under conditions, and the details matter:
- A permit comes first. On either visa you must get permission from immigration before working. Working without it risks your status.
- Hours are capped, and the cap depends on your level and Korean ability. Higher study levels and stronger TOPIK scores generally unlock more hours.
- D-4 students face tighter limits and usually a waiting period before they can work at all.
- Some jobs are off-limits on a student visa regardless of hours.
The current numbers change, so confirm them before you take a job. The details are in part-time work on a D-2 and part-time work on a D-4.
Converting a D-4 to a D-2
This is the path many language students take: study Korean on a D-4, get admitted to a degree, and switch to a D-2, often without leaving the country. The mechanics are covered in from language institute to university, but two things decide whether it goes smoothly.
The second factor is meeting the degree program's own requirements, including the TOPIK level it asks for and its admission documents. Convert once you are genuinely admitted, and time the change so there is no gap in your status.
