UK Border Rules Change; Dual Citizens Risk Stranding

The UK rolls out sweeping digital border changes on February 25, 2026, enforcing electronic travel authorizations (ETAs) for eligible visitors and shifting visitor visas to eVisas only, ditching physical stickers for seamless UKVI account access. Dual British nationals face the sharpest hurdles: they must wield a valid British passport or a pricey £589 Certificate of Entitlement (CoE) to board flights, ferries, or trains, or risk outright denial and stranding abroad.
