Changing from D-4 to D-2: Admission, Change of Stay Status, and Work Permission Must Be Checked Separately

Students admitted to a degree program while studying Korean on D-4-1 should treat university admission, change of status of stay to D-2, and part-time work permission as three separate gates. The university handles admission, enrollment, and the Standard Admission Letter; the competent immigration office reviews the change to the D-2 subclass that matches the actual degree program; and part-time work requires confirmation by the university staff member and immigration permission for activities outside the status of stay.

Start with the current D-4 expiration date and work backward through the tuition payment deadline, Standard Admission Letter issuance date, immigration filing date, and review status. Set the work start date only after both the D-2 approval result and part-time work permission status have been confirmed.

Three Gates and Their Completion Criteria

1. Determine the D-2 Subclass at the University-Admission Stage

Study in Korea guidance on student visas and status of stay distinguishes D-2 for degree programs from D-4 for non-degree training. If a student in D-4-1 Korean-language training enters a regular degree program at associate level or above, they should prepare to change to the D-2 subclass that matches the actual program.

The D-2 subclass must match the program you will actually enter. Confirm these three items with the international office.

1. The D-2 subclass to be shown on the Standard Admission Letter
2. Date the Standard Admission Letter will be issued
3. Whether the university uses group filing and its filing schedule

Even when using university group filing, check the filing date, any request for additional documents, and your individual approval result yourself.

2. Work Backward from the D-4 Expiration Date to Schedule the D-2 Change

The schedule should be anchored to the current D-4 expiration date, the Standard Admission Letter issuance date, the actual immigration filing date, and the approval result. Plan the filing and review timeline so it runs within the current D-4 period of stay, and start work that depends on the new status only after the approval result is confirmed.

3. Prepare D-2 Change Documents as a Common Set and a Case-Specific Set

Using HiKorea’s Foreign Resident Stay Guide, July 2026 edition together with Study in Korea guidance, the preparation items can be grouped as follows.

The actual submission package is determined by your nationality, the university’s certification and review type, the filing office, and your history of stay. Check the required financial-capacity documents and amount against the current guidance for your nationality, university, and filing office; do not use an amount from an old university admissions guide as a universal benchmark. If you use a bank balance certificate in a parent’s name, prepare proof of the family relationship as well.

For highest educational qualification, financial, and family-relationship documents, separately check the issue date and whether translation, notarization, or an apostille is required for university admission and for immigration filing. When reusing a document submitted in one procedure for another, recheck whether the receiving institution accepts it and match the required submission format.

4. Schedule Part-Time Work Permission Separately

According to Study in Korea guidance on activities outside the status of stay, part-time work for D-4-1 and D-4-7 language trainees requires that 6 months have passed from the date of status change or the date of entry on the visa, followed by confirmation from the university staff member and immigration permission.

Part-time work in a D-2 degree program also requires prior permission consistent with the applicable D-2 subclass, Korean-language proficiency, academic status, and permitted hours. A student who had part-time work permission under D-4 should confirm with university staff and the competent immigration office whether a new permission or change procedure is required after changing to D-2.

Set the work start date only after both the D-2 approval result and the part-time work permission status have been confirmed. The date of acceptance and the tuition payment date belong to the university-admission schedule, while the date when work may actually begin depends on the status of permission for activities outside the status of stay.

Preparation Order

1. Confirm the final admission result and tuition payment deadline with the university you want to attend.
2. Ask the international office about the D-2 subclass, Standard Admission Letter issuance date, and whether the university uses group filing.
3. Calculate the gap between the current D-4 expiration date and the degree program start date.
4. Check the issue dates of highest educational qualification, financial, and family-relationship documents and whether translation, notarization, or an apostille is required.
5. Check HiKorea or the competent immigration office for the documents and available appointment dates that apply to your nationality, university, and history of stay.
6. Confirm the D-2 filing/receipt status, any request for additional documents, and the approval result, then set the work schedule after completing any new part-time work permission or required change procedure.
