D-4 Language School Visa Extension Checklist

D-4 Language School Visa Extension Checklist is written for international students and applicants working with Korean schools or immigration. Requirements vary by university, visa code (D-2, D-4, and others), and nationality, treat every list as a starting map, then confirm the live checklist.

HezoKorea helps package admissions and visa documents so your file matches what the school and embassy actually ask for in 2026.

1. Confirm the exact program, intake, and visa category on the school’s international page.
2. Gather civil and academic documents early, apostille/legalization queues can take weeks.
3. Align language scores (TOPIK / TOEFL / IELTS) with the program’s language of instruction.
4. Build a buffer before embassy or HiKorea appointments; score reports and COE letters slip.
5. After entry, complete ARC registration on the timeline your status requires.

• Passport biodata page and prior Korean visas/ARC copies if any
• Academic transcripts and diplomas (apostilled/legalized when required)
• Financial evidence naming the correct sponsor
• Photos that meet immigration or school specs
• Certified translations when the original is not in Korean (or English if accepted)

Confirm current forms on HiKorea or your embassy’s study checklist before you pay fees.

Schools and immigration update forms mid-cycle. Download the newest PDF the week you apply, match name spellings to your passport, and keep digital scans of everything you submit.

Confirm before you act: Korean immigration, university, and shipping rules change. Treat lists and timelines here as orientation, re-check HiKorea, your embassy checklist, or Korea Post / carrier pages on the day you apply or ship. HezoKorea re-verifies steps when we prepare your case.
