UK Requires Dual Citizens to Use British Passport for Entry

UK authorities have announced a new rule effective February 25, 2026, requiring dual citizens to present a valid British passport when entering the country. Failure to do so may result in being denied boarding on planes, ferries, or trains.

The UK Home Office explained that this measure is part of an update to the border control system, linking it to the Electronic Travel Authorization (ETA) requirement, which applies to visitors from around 85 countries.

Under the new rule, dual citizens cannot rely solely on their foreign passports for entry. They must present a British passport or a certificate of entitlement attached to their second passport, with a fee of up to £589.

British and Irish citizens using their original passports are exempt, and the ETA system continues to apply for non-British and non-Irish visitors.

Officials stated that the change aims to strengthen border controls and streamline the digital travel experience. However, the decision has drawn criticism from dual citizens who view it as an added financial burden and a potential complication when planning travel or returning home.

Travelers are required to ensure they carry the necessary documents after February 25, or they may be denied entry to the UK or refused boarding.
