D-4 Language Study Visa: Requirements & Process
The D-4 language study visa explained: who it's for, requirements, documents, the application process, working rules, and switching to a D-2 degree visa.
The D-4 language study visa is how most people come to Korea to learn Korean before starting a degree. It's designed for non-degree study — mainly university language institutes (한국어학당). This guide covers the requirements, documents, process, and how to move on to a D-2 later.

Who the D-4 is for
- Learners enrolling in a university language institute or similar non-degree course.
- People who want to study Korean first, then apply for a degree on a D-2.
If you're enrolling directly in a degree, you need the D-2 instead — see our D-2 vs D-4 guide.
Requirements

Working & attendance
You can apply for a part-time work permit under conditions (limits are stricter than for degree students). Attendance matters — poor attendance can affect renewals and permits.
Moving to a D-2
Once admitted to a degree program, change status to a D-2 — ideally before your D-4 expires.
