D-4 Language School Transfer: The 6-Month Rule and What…

Switching schools sounds simple. It isn’t.

You came to Korea on a D-4 visa and started Korean classes. Now something feels off. Maybe the classes are too big. Maybe the commute eats two hours a day. Maybe a friend’s institute just looks better. So you find a new school, get an offer, and plan to move next term.

Here’s the problem. Your D-4 status is tied to the institute that admitted you. Move without approval and your whole stay can be put at risk. Below, you’ll find the permission rule, the waiting period, the paperwork, and what really happens if immigration says no. D-4 visa Korean language student guide

Why can’t you just enroll at a new language school?

Because your D-4 stay is linked to one specific institute. The Korea Immigration Service treats a language school transfer as a change that needs approval, not a simple re-enrollment. You apply for D-4 visa change language institute permission at the immigration office covering your address. You do this before starting classes at the new school. Studying elsewhere without approval can count as a status violation.

One visa, one sponsor

The D-4 visa covers general trainees. Most language students hold the D-4-1 subtype. It’s for Korean language training at a university-affiliated institute, called an eohakdang in everyday Korean.

Your institute is your sponsor. It issued the admission letter you used for your visa. It also records your status in FIMS, the Foreign Student Information System used with the Korea Immigration Service. When you stop attending or withdraw, the school has a legal duty to report it.

Summary of Immigration Act Article 19-4 (via MOLEG): the head of a school that admits foreign students must manage their stay and report to the immigration office when a student fails to register, takes leave, is expelled or withdraws, or cannot be located.

That report is why a quiet move backfires. Your old school reports you as gone. Your new school can’t legally register you. On paper, you’re a D-4 student studying nowhere.

Transfer vs. status change

Don’t mix up a school transfer with a status change. Moving from one language institute to another keeps you on D-4. Moving from a language institute into a degree program means changing from D-4 to D-2. That’s a different application with different documents. Check which one applies to you on HiKorea before you book anything. D-4 to D-2 visa change

So when are you actually allowed to apply? It comes down to one number most students learn too late.

How long do you have to study before you can leave?

Immigration’s D-4 guidance generally sets a minimum study period before transfer of 6 months. At most university institutes, that equals two terms. Applications filed earlier are normally refused. Exceptions exist when the first institute closes, loses its ability to host foreign students, or can’t run your course. Each exception still needs written proof and an officer’s approval before you move.

Why the 6-month rule exists

Short-stay school hopping has long been a red flag for immigration. Some brokers used language institutes as an entry ticket. Students then moved to cheaper schools or dropped out to work. The waiting period gives immigration a real study record before it approves a move.

It’s a fraud filter. Not a punishment.

How the clock is counted

Many university institutes run four 10-week terms a year. Two completed terms usually reach the 6-month mark. The count runs from your actual study at the first school, not from your visa issue date. Did you defer a term or arrive late? Then your clock started later than you think.

Ask your international office for a certificate of enrollment showing your start date. That one line answers the timing question before you ever visit immigration.

Exceptions that can open the door early

Officers can consider an earlier transfer when the problem is the school, not you. Typical cases include:

• The institute closes or shuts down its language program.
• The school loses its ability to host foreign students after a poor government quality review.
• Your course level is no longer offered.

Each case still needs proof. Approval stays at the officer’s discretion.

Check the new school’s standing

The Ministry of Education runs IEQAS, the International Education Quality Assurance System. Each year it publishes lists of certified universities and visa-restricted universities. A transfer into a visa-restricted institution is a hard sell. You can also check program details on Study in Korea, run by NIIED, the National Institute for International Education.

Once you’ve cleared the waiting period, the next hurdle is paper. Lots of it.

The paperwork stack immigration expects on your desk

The required documents for a school transfer at immigration usually include the Integrated Application Form (Form No. 34), your passport, your ARC and the fee. You also need the new institute’s admission letter and business registration certificate. From your current school, bring attendance and grade certificates. Officers can request more, such as proof of funds or housing. Bring originals plus copies.

The core document set

Officers can ask for more. A release letter from your old school isn’t always required. Still, some offices and institutes expect one. Ask both schools before your appointment.

Step by step

1. Talk to your current institute. Tell the international office you plan to transfer. Request attendance, grade and enrollment certificates. Ask whether they issue a release letter.
2. Secure your new admission. Apply to the new institute. Get the standard admission letter and its business registration certificate.
3. Book a visit on HiKorea. Use Visit Reservation for the office that covers your registered address. Book early, since slots near term starts go quickly.
4. Attend and submit. Bring originals and copies. If the officer asks why you’re moving, answer plainly and honestly.
5. Keep studying while you wait. Don’t start classes at the new school before approval. Don’t stop attending your current one either.
6. Finish the move. After approval, register at the new institute so it can update FIMS. If you moved house, report your new address within 15 days under Immigration Act Article 36. You can file at an immigration office, your local community center, or through HiKorea e-Application. ARC address change report Korea

All of this assumes your record is clean. What if your attendance is already shaky?

What happens when your attendance is already low?

Transfer after poor attendance is possible on paper but hard in practice. Officers read your attendance certificate first. Low attendance is the clearest sign that a student isn’t really studying. Many institutes flag students who fall below 70% in a term. Below that line, expect a refusal, extra questions, or a request to improve your record before you reapply.

Why attendance carries so much weight

A language institute exists to teach. If you’re not in class, immigration assumes you’re doing something else. Often that means unauthorized work. Your attendance certificate is the fastest way for an officer to check.

But it gets worse. A transfer request on top of weak attendance looks like an escape. The officer may suspect you’re leaving before your school reports you. That’s why low numbers often lead to refusal, even when your reason sounds fair.

Can a strong reason outweigh weak numbers?

Sometimes. It depends on proof. Officers can weigh documented reasons such as:

• An illness or hospital stay, backed by records from a Korean hospital.
• A family emergency abroad, backed by travel records and supporting papers.
• Problems caused by the school, such as cancelled classes.

A general complaint won’t offset missed weeks. Saying you didn’t like the teacher isn’t a reason an officer can verify.

Fix the record first

If your attendance is low, the smartest move is often to wait. Finish one strong term at your current school. A clear upward trend gives the officer something positive to read.

Watch your work rules too. D-4 students need separate permission for part-time work. Working without it can sink any later application, including a transfer. D-4 part-time work permit

And if the answer is still no? Your visa doesn’t vanish on the spot. But a clock starts ticking.

Denied? Here’s where that leaves your visa

Your visa status when transfer is denied depends on one question. Are you still enrolled at your original institute? If yes, your D-4 stays valid and you keep studying there. If you already withdrew, the school reports it. Immigration can then shorten your stay or ask you to leave. That’s why you should never withdraw before approval arrives.

Three common situations

Here’s what actually happens after a refusal. You receive a notice with a reason. It usually points to one of three gaps: time, attendance or documents. Each gap has a different fix.

Your options after a refusal

1. Reapply later. If the issue was the 6-month rule, wait and reapply with fresh certificates.
2. Strengthen the file. If attendance or missing papers caused the refusal, fix that first and return.
3. File an administrative appeal. Under the Administrative Appeals Act, you generally have 90 days from learning of the decision. You can file online through the Central Administrative Appeals Commission. An appeal doesn’t extend your legal stay on its own.
4. Start fresh from home. Some students leave Korea and apply for a new D-4 visa at a Korean embassy with the new school’s admission. It resets the paperwork. It also costs time and airfare.

Never overstay while you sort this out. Overstaying can lead to fines and entry bans that block future study in Korea.

Most of these problems are avoidable. The fix happens before you sign anything.

Before you sign with a new school, check these five things

Before paying a new institute, confirm five things. You’ve reached the 6-month mark. Your attendance is solid. The new school can legally host D-4 students. Your current school will issue your certificates on time. Your stay has enough time left to cover processing. If any point is unclear, call the Immigration Contact Center first. Paying first and asking later is how students lose tuition.

The pre-transfer checklist

• Time: Count two full terms at your current institute.
• Attendance: Get your certificate and read the numbers yourself.
• School status: Check the new school’s IEQAS standing with the Ministry of Education or Study in Korea.
• Paper trail: Confirm your current school will issue certificates before your appointment.
• Runway: Make sure your stay covers processing time plus a possible refusal.

When to call 1345

The Immigration Contact Center at 1345 answers in Korean, English, Chinese and many other languages. Call it if your case involves an exception, a medical gap, or a stay date close to expiry. Write down the date, time and the agent’s answer. A noted answer is useful if your case gets complicated later.

Your next step

Open HiKorea and check the current fee and document list for your office. Then book a visit. Bring the full set the first time. A second trip can cost you weeks you may not have. D-4 visa extension
