UK ETA Mandatory: Digital Certificates from Feb. 26

The UK makes Electronic Travel Authorisation (ETA) mandatory from February 26, issuing digital certificates that replace paper proofs for visa-exempt visitors. Travelers apply via the UK ETA app, providing passport details, a photo, and suitability answers for a quick decision, often in minutes, at a £16 fee. ETAs permit multiple six-month stays over two years, linked to the same passport used in the application.
