Any foreign visitors wishing to enter the Republic of Korea must have a valid passport and obtain a Korean visa before the visitation. For nationals in countries eligible for visa-free entry to Korea, one must obtain K-ETA. This is a new measure put in force in Oct. 2021. Please make sure to check whether you need a Korean visa or K-ETA.

※ Starting July 1st 2020, The Embassy of the Republic of Korea (ROK) issues a Confirmation of Visa Issuance in place of a visa label as an entry permit into Korea.

Please visit the Korea Visa Portal website or contact your local Korean Embassy for accurate visa information, as rules and regulations vary depending on the country you’re coming from. The Korean government may have suspended visa exemptions and visa-free entry for foreign nationals in some countries due to Covid-19. Therefore, all individuals in those countries may be required to apply for a visa before travel even though they were previously eligible for visa-free travel to Korea. The list of countries affected by this measure can vary at any time with changes in Covid-19 circumstances; please make sure to check the up-to-date entry requirements before leaving for Korea.
