13 Visa Updates That Could Derail Your 2025 Travel Plans

8. South Korea Tightens K-ETA Enforcement

South Korea’s K-ETA system, which allows visa-free travelers to register before arrival, was once lax in enforcement—but no more. In 2025, immigration officials are cracking down on compliance, particularly for repeat visitors or those staying more than a few weeks. Denied entries and turned-away flights are becoming more common for travelers unaware of the need to apply in advance. K-ETA is affordable and valid for two years—but it’s not optional. Don’t risk boarding without it. Even layovers with overnight transfers may now require valid authorization. Double-check requirements for your nationality before you board that flight to Seoul.
