Frequently Asked Questions
When can I apply for a visa extension?
Generally from 4 months before expiry (varies by status). Immigration office visits require a HiKorea reservation, so start preparing at least 1–2 months ahead.
What happens if I overstay?
Overstay fines scale with duration, and it can hurt future visa applications and re-entry. If expiry is imminent, contact immigration right away — and reach out to WeBring if you need help in your language.
What documents do I need for an extension?
It depends on your visa status. Commonly: passport, ARC, application form, and fee, plus status-specific proof (enrollment certificate, employment contract...). Ask us for the exact list for your visa.
