2. K-ETA (Korea Electronic Travel Authorization)

Nationals of countries/regions eligible for visa-free entry are required to get K-ETA approval to board the flight bound for the Republic of Korea. K-ETA approval should be applied at least 72 hours prior to boarding the flight bound. You can apply for the K-ETA website ( or mobile app (K-ETA). Apply for K-ETA

   Foreign visitors who do not require a visa must obtain a K-ETA permit to board a flight bound for Korea.
  Please apply at least 72 hours before departure by accessing the K-ETA website or mobile app (K-ETA) (as assessment can take "more than 72 hours" depending on the situation).
  K-ETA is valid for two years after issuance, and the number of arrivals is irrelevant. However, if the validity period of the passport is within two years when applying for K-ETA, the K-ETA is valid only until the validity period of the passport.
   (K-ETA is not a visa. The issuance of K-ETA does not guarantee the entry of the Republic of Korea, and the entry availability of Korean immigration officials is finally determined according to the results of the immigration inspection.)
