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.

Planning a D-4 → degree path? Ask a consultant.

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

  • Acceptance into a recognized language institute/course.
  • Proof of funds — bank balance certificate covering tuition and living costs.
  • Valid passport and clean record.

The process

  1. Enroll and get your admission documents.
  2. Prepare your documents and current bank certificate.
  3. Apply at your Korean embassy/consulate.
  4. Pay the fee and wait for processing.
  5. Enter Korea, then register for an ARC.

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.
