South Korea D-2 Student Visa Guide

D-2 vs D-4: which student visa you need

South Korea issues different visas for different kinds of study. The D-2 visa is for students enrolled in a full degree programme at a recognised Korean university — associate, bachelor's, master's, doctoral, or a formal research programme. If you have an offer for a degree course, the D-2 is normally the visa you apply for.

Shorter or non-degree study uses other categories. A language-training course at a university language institute, for example, typically uses the D-4 visa. Confirm the exact category with your admitting university and the Korean embassy, because the paperwork differs.

Throughout this guide, rules such as document lists, financial thresholds, fees and processing times are set by the Korean government and each diplomatic mission, and they change. Treat everything here as general information, not immigration advice, and verify the current requirements on the official websites listed below before you apply.

Step 1: Secure admission and your Certificate of Admission

The visa process starts with a university, not the embassy. First, receive and accept an offer of admission from your Korean university and complete whatever it requires — this usually includes paying tuition or a confirmation fee.

Once that is done, the university issues a Certificate of Admission (COA), sometimes called a standard admission letter. This is the central document for your D-2 application: it confirms you are a genuine, enrolled student.

Universities also handle much of the immigration side. Some issue a visa issuance confirmation (or a confirmation number) through the immigration system, which can simplify or speed up your embassy application. Ask your university's international office exactly which route it uses.

• Accept your offer and complete the university's enrolment and payment steps
• Receive the Certificate of Admission (COA) / standard admission letter
• Ask whether the university issues a visa issuance confirmation number

Step 2: Apply for the D-2 visa

With your COA in hand, you apply for the D-2 visa at the Korean embassy or consulate responsible for your region, or start the application online through the Korea Visa Portal (visa.go.kr). Some missions require an in-person appointment or interview; others accept applications by post or through an approved channel.

Each mission publishes its own document checklist, fees and processing time on its official page, so use the checklist for the specific embassy that covers you rather than a general list.

Because requirements vary by country and can change with little notice, confirm the current process on the Korea Visa Portal and your embassy's website before booking flights or making payments.

Documents you'll typically prepare

Exact requirements are set by each mission, but D-2 applicants are commonly asked for a core set of documents. Prepare originals and clear copies, and follow any translation or notarisation rules your embassy specifies.

Proof of finances is a key part of the application — you generally need to show you can fund your studies and stay. The amount and the acceptable form of proof (bank balance, sponsor, or scholarship award) are set by the mission, so verify the current figure on the official website rather than relying on a number from a forum.

• Passport and completed visa application form with a photo
• Certificate of Admission (COA) from your Korean university
• Academic records (diplomas, transcripts) as required
• Proof of financial means — amount set by the mission; verify officially
• Any health or tuberculosis (TB) test document your mission requires

After you arrive: register as a foreign resident

Getting the visa is not the last step. Students who stay long-term must complete foreign resident registration and receive a Residence Card (previously called the Alien Registration Card, or ARC) — the official ID you use in Korea for banking, a phone plan, health insurance and more.

This is done at your local immigration office, and appointments are booked in advance through HiKorea (hikorea.go.kr), which is often busy. Registration must be completed within the deadline after arrival — currently within 90 days — so book early.

Avoid travelling out of Korea before your card is issued unless you have confirmed it is safe to do so, as leaving at the wrong time can affect a single-entry visa. Check the current rule with immigration first.

Staying legal: extensions, changes and health cover

Your D-2 status has conditions. You must remain an enrolled student, keep your registered address updated, and apply to extend your stay before it expires if your programme runs longer. Changing your situation — switching schools, taking on part-time work, or moving to a post-study status — usually needs a separate permission or notification.

Health insurance is part of staying compliant: enrolment in Korea's National Health Insurance Service (NHIS) is mandatory for international students, and unpaid premiums can affect a future visa renewal.

All of these steps are handled through immigration and HiKorea, and the specifics change — always confirm the current procedure on the official website.

Common pitfalls and a scam caution

Most problems come from small, avoidable mistakes: applying with an out-of-date document list, underestimating processing time, or missing the arrival-registration deadline. Build in extra time and use only the checklist your specific embassy publishes.

Be cautious with agents. No agency can 'guarantee' a Korean student visa — the decision rests solely with the Korean authorities — and paying for such a promise is a red flag. You never need to pay a third party for official forms, which are free on the government portals.

When anything is unclear, contact your university's international office or the embassy directly. This guide is general information, not immigration advice; the official sources below are always the final word.
