UK Mandates ETA for Visa-Free Travelers, Including Koreans

The United Kingdom enforces its Electronic Travel Authorisation (ETA) scheme starting February 25, 2026, requiring nationals from 85 visa-exempt countries, including South Korea, the US, Canada, and most EU nations, to obtain digital pre-approval before boarding flights. British and Irish citizens remain exempt, while the £16 application via the official UK ETA app delivers most approvals in minutes, valid for multiple entries over two years or until passport expiry.
