In an upcoming change to border regulations, British dual nationals will be required to present either a British passport, a visa, Electronic Travel Authorisation (ETA), or a certificate of entitlement to enter the UK. This new rule, which comes into effect on 25 February, means that if dual nationals do not have a British passport, they could be denied boarding on flights, trains, or ferries to the UK, significantly complicating travel plans for many.

Previously, dual nationals could travel to the UK using their foreign passport without needing to present any additional documentation, but this has changed under the new regulations. Many families and individuals with ties to the UK may find themselves unprepared for the complexities of these requirements, as they highlight the increasing scrutiny on who can enter the UK and under what circumstances.

The rules particularly affect those who might have previously relied on their foreign nationality for easier access. As British and Irish citizens have the historic right to live in the UK, proving this status has now become a bureaucratic hurdle for dual nationals, likely leading to confusion and potential disruptions at borders and departure points.
