K-ETA is mandatory for travelers from over 100 countries, including major destinations like the United States, Canada, most European nations, and Australia. However, not all nationalities are required to obtain a K-ETA. Citizens from certain countries can still visit South Korea without it or may be eligible for other travel arrangements. To ensure you’re eligible, check the official K-ETA website for a complete list of countries.
