The South Korea Travel Visa has not been made available yet and the finalized list of eligible countries has not been announced. The electronic visa will be launched later on this year.
To obtain a visa for South Korea travelers can go to an embassy or consulate to complete an application. Once available, the South Korea Tourist Visa will eliminate this need.
At the moment, citizens from a number of countries can visit South Korea without a visa for limited time periods. Travelers from the USA, all EU countries, Australia, New Zealand, Brazil, Argentina, and Japan, can enter for up to 90 days visa-free.
Canadians can enter for up to 180 days without a visa and there are other nationalities who can enter visa-free for up to 30 days or 60-days, depending on their country of origin.
