C-3-3 指南

행정사的建议

• Always use a KTO-licensed medical tourism coordinator if you are unsure about which hospitals are eligible — they handle the invitation letter and visa paperwork as part of their service.

• The December 2025 companion expansion includes siblings and designated caregivers — if you need a sibling to accompany you, request the updated companion application form from the hospital.

• If treatment costs are being paid by your home country's insurance, obtain a pre-authorization letter confirming Korea is covered. This substantially strengthens your financial proof.

• C-3-3 extensions are processed at the immigration office with a hospital letter confirming treatment is ongoing. Extensions are generally approved if treatment is genuine and in progress.

• Medical tourism coordinators (의료관광 유치업자) must be KTO-licensed. Using an unlicensed broker is illegal in Korea and can complicate your visa.
