Valid passport (at least 6 months validity) and Korean visa are required to enter the Republic of Korea. For more accurate information, we recommend you to contact a Korean Embassy in each country to ask about the necessary documents for visa issuance. It is also highly recommended to apply for a visa at least one month before your departure for the Republic of Korea as your visa process may take time. Nationals of those countries or regions with which Korea has signed a visa waiver agreement can enter without a visa up to 30 or 90 days. For more information on visa issuance, please visit the website of the Ministry of Foreign Affairs of the Republic of Korea.

The 'K-ETA' (Korea Electronic Travel Authorization) is for nationals of countries/regions eligible for visa-free entry and are required to get K-ETA approval to board the flight or ship bound for the Rep. of Korea.
You can apply for a 'K-ETA' from here and it takes around 1 week to be issued. We recommend you apply for this in advance to ensure you have the authorization in time.
