Tens of thousands of dual nationals face potential travel chaos this week as the United Kingdom prepares to enforce strict new border regulations.
Starting Wednesday, February 25, 2026, the “fudge” of traveling to the UK on a non-British passport will officially come to an end, with airlines warned to deny boarding to those without correct documentation.
Historically, dual citizens (such as those holding both UK and US or EU passports) could travel using their foreign document. However, under the fully implemented Electronic Travel Authorization (ETA) system, this is no longer possible.
Because British citizens are legally exempt from needing an ETA, the digital system will block them from obtaining one. Consequently, carriers cannot verify their right to enter unless they present.
A valid British or Irish passport.
A Certificate of Entitlement (Right of Abode) linked to their foreign passport.
The change has sparked outrage, particularly due to the £589 fee for a Certificate of Entitlement.
In a last-minute “lifeline,” the Home Office clarified that carriers may allow boarding if a traveler presents an expired British passport (issued after 1989) alongside a valid foreign one, though this remains at the carrier’s discretion.
With humidity-thick fog already delaying flights in regions like Karachi, travelers are urged to verify their documents immediately to avoid being stranded.
