A valid KETA allows multiple entries to South Korea.
There is no specific limit on the number of times you can enter during the validity period.
The KETA is generally valid for up to three years from the date of approval, or until your passport expires, whichever comes first.
Each stay must comply with the maximum stay period allowed under visa-free entry rules.
If your passport expires, your personal information changes, or the KETA validity period ends, you must apply for a new KETA before traveling again.
