Keeping D-4 Status: Registration, Attendance, Work

Getting the D-4 was one problem. Keeping it is a different one, and it is administrative rather than academic.

Five things interlock: alien registration, the reported address, attendance, the extension, and permission to work. A failure in any one of them surfaces at the next extension or the next change of status, often months after the mistake.

How the visa is issued in the first place — the certificate of admission, financial evidence, and what consulates refuse on — is in the D-4 visa for studying Korean. This guide begins the day you land.

The dangerous mistakes are the ones nobody stops you from making.

1 · Alien registration, within 90 days

Article 31 of the Immigration Act requires a foreign national intending to stay beyond 90 days from entry to register within 90 days of entry. A D-4-1 trainee is on a long stay by definition, so this is not optional and there is no reason to leave it late.

Registration is not an ID card errand. The registration number it issues is what a bank account, a phone contract, a lease, health insurance and online identity verification all run on. Register late and the whole of your practical life is late with it.

Booking, and what to bring

Confirm your jurisdiction, then book through HiKorea. Ask your institute’s international office first — some schools submit as a group, which removes the booking problem entirely.

The residence proof is what fails. A lease in your own name is straightforward and a dormitory confirmation is straightforward. Living in someone else’s place needs a written accommodation-provision confirmation plus evidence of that person’s identity and right to the property. Sort this out with the room, not after the appointment is booked.

2 · Moving means reporting, within 15 days

Once registered, your address is a declared fact with an obligation attached. Article 36 of the Immigration Act gives a registered foreign national 15 days from the date of moving in to report the change.

Report at the si/gun/gu or eup/myeon/dong office covering the new address, or at the immigration office. HiKorea handles it online where the case supports it. Bring the registration card and proof of the new address.

What does not count: filling in a residents card at the building management office, telling the landlord, or updating your bank. Those are separate administrations that happen to involve the same address. Management offices in particular have nothing to do with immigration — what they actually govern is in management offices in Korean apartments.

This catches language students constantly, and always the same way: the first room is temporary, moving into a real one feels like part of arriving, and nobody mentions the clock.

3 · Attendance is the evidence, not a school rule

D-4-1 is permission to be here for a specific purpose. When immigration assesses an extension it is not only checking that tuition was paid — it is checking that the training actually happened.

Attendance and grades are the documents that answer that.

University language institutes generally manage attendance strictly, and 80% recurs as the institute’s own threshold for progressing a level, re-enrolling, or transferring to another institution. The government’s Study in Korea materials show 80% used that way.

Long absences do not stay inside the school

If a student is absent for an extended period, cancels enrolment or stops studying, the consequence is not confined to academic administration. Under the framework for managing foreign students, the institution reports the change to immigration — and the Ministry of Justice publishes notices where such reports have led to summonses and to changes in stay permission.

So an unavoidable absence — illness, a family emergency — is handled by telling the school at the time, and keeping the documentation. Clinic receipts, certificates, whatever exists. The worst available approach is accumulating unexplained absences and then explaining them at the extension counter.

Absence reported at the time  →  a record
Absence noticed at extension  →  a problem

4 · Part-time work is a permission, not a right

D-4-1 is not an employment status. Convenience store, restaurant, café — any paid part-time work requires meeting the conditions and obtaining permission from immigration first.

The conditions

Actual permitted hours depend on the institution’s certification status and the guidance in force at the time. Confirm both with your international student officer and with immigration before signing anything, because these are the figures most often quoted from a forum post two years old. This site tracks them: D-4 part-time work conditions.

The sequence, and where people break it

Employer agreed
  → employment contract written
  → part-time work confirmation completed
  → international student officer confirms
  → application via HiKorea or the immigration office
  → permission granted
  → first shift

The break happens between the contract and the permission. Having a signed contract is not permission to work. The contract is one of the documents you submit in order to be permitted. Starting before the permit is granted is unauthorised employment, and it does not stay in the past — it surfaces at the next extension and at every later application.

Permission does not cover every job

Part-time work under D-4 assumes ordinary work a student would normally do. Gambling-adjacent and entertainment industries, work connected to gambling activity, and work inconsistent with the purpose of study or restricted by law can fall outside what is permitted.

Private tutoring is not treated like a shift at a convenience store. Government guidance says it is managed strictly, given the particular circumstances of where and with whom it happens.

Which means the pattern of finding a job first and fitting the permission around it afterwards is exactly backwards. Confirm the work is permissible before you agree to it.

5 · Prepare the extension by the term, not by the deadline

Because attendance and grades are what the extension turns on, checking your attendance a month before applying is too late — the term that produced it has already finished.

Once a term, check these together:

6 · Plan the status after this one

D-4-1 exists for language training. It is a stage, not a destination.

• A degree — consider changing status to D-2.
• Job hunting after the programme — D-10.
• Employment — E-7 and the other work statuses.

A clean D-4 record is not just about staying now. Attendance, reported addresses and properly permitted work all form the history that later applications are assessed against.

Alien registration
  → address correctly registered, and re-registered on every move
  → attendance and grades managed each term
  → extension
  → part-time permission obtained in advance where needed
  → programme completed
  → D-2, D-10 or E-7 considered

What actually goes wrong

Not the expiry date. Almost everyone watches the expiry date.

What accumulates quietly is: a student who is barely attending and believes the valid visa means everything is fine; work started without the school’s confirmation and immigration’s permission; an address that changed and was never reported. Each is invisible until an extension, and by then none of them can be undone.

The banking and phone steps that unlock after registration are in opening a bank account in Korea as a foreigner and Korean phone plans for foreigners; health insurance is in NHIS health insurance for foreigners.
