D-2 / D-4 student extension & part-time work permit (시간제취업): 2026 document checklist
A step-by-step guide for D-2/D-4 students to extend their period of stay and obtain a part-time work permit — documents, fees, and where to apply.
Students on D-2 (degree programs) and D-4 (language training / university preparatory) status must obtain an extension of stay (체류기간 연장허가) before their alien registration card expires. Students who wish to work part-time must separately apply for permission to engage in activities outside their status of stay (체류자격외활동허가), commonly known as the 시간제취업 part-time work permit.
This page summarizes the required documents, fees, and where to apply for both procedures, based on official information from HiKorea and the Korea Immigration Service. Requirements can vary by office, so verify with HiKorea or call the 1345 hotline before filing. Timing matters: an extension can be filed as early as four months before the alien registration card expiry date and no later than the expiry date itself, while a part-time work permit must be obtained before any work begins. The two applications are independent — extending the period of stay does not by itself grant the right to work, and the part-time permit does not extend the period of stay. Most students only need the core study documents plus the part-time set described below, but it is always worth confirming the exact list for your situation, because immigration offices may waive the transcript and attendance certificate when the school has already entered the data into the UIIS system (유학생정보시스템), or ask for additional proof of finances or residence depending on your circumstances. Reading the requirements carefully and preparing each document in advance is the most reliable way to avoid a repeat visit or a missed deadline.
Steps
1Prepare the D-2/D-4 extension documents
Assemble the 통합신청서 (별지 제34호서식), 여권, 외국인등록증, an ID photo, 재학증명서, transcript and attendance certificate, 잔고증명서, proof of tuition payment, and proof of residence (체류지 입증서류). Download the application form for free from hikorea.go.kr.
2Submit the extension before the ARC expiry date
You can apply as early as four months before the alien registration card expiry date and up to the expiry date itself (online filing via 전자민원: no later than one day before). Apply at the 출입국·외국인청 for your registered address; book an appointment in advance through HiKorea (방문예약). The extension fee is ₩60,000.
3Check your part-time work (시간제취업) eligibility
D-2 students may apply after enrollment; D-4-1 (language training) students must have stayed at least six months from the date of entry or the date of change to D-4. Permitted working hours follow the current guideline (관리지침) — for example, TOPIK level 3 or above allows up to 20 hours per week during a regular semester, with no limit during vacation.
4Prepare the part-time work permit documents
Assemble the 체류자격외활동허가 신청서, an employment contract (근로계약서) with the workplace, the school's part-time confirmation (유학생 시간제취업 확인서), a transcript or attendance certificate, and Korean-language proficiency evidence (TOPIK; fully English-taught programs may substitute an equivalent TOEFL/IELTS).
5Submit the part-time application & receive the result
Apply at the 출입국·외국인청 for your registered address or through HiKorea online. The 시간제취업 part-time work permit is free (₩0) for students. When changing workplace, only a notification (신고서) is required — no new permit from scratch.
