Documents and Visa Rules in South Korea: what actually matters to know

From real experience

ruleSouth Korea requires proof of travel insurance for certain visa types and may ask for it during immigration checks, especially for extended stays or specific purposes.
While not always explicitly demanded for K-ETA-based tourism for all nationalities, it is highly recommended. Travel insurance can cover medical emergencies, trip cancellations, and lost belongings, providing financial protection during your stay. Verify specific requirements based on your nationality and visa type.

ruleRussian citizens with an expired visa but a valid Korean ID card can generally re-enter South Korea.
Most long-term visas and ID cards are automatically extended within Korea. It is advisable to confirm the specific visa type and its extension policy, as some may have limitations (e.g., single extension possibility). However, a valid ID card usually suffices for entry.

ruleFor F4 visa holders in Korea, re-entry is permitted as long as the 'Period of stay' on the ARC card has not expired.
Unlike other visa types, the F4 visa is generally not annulled after one year of absence from Korea. Always check the expiry date on the Alien Registration Card (ARC) for re-entry eligibility.
