London, United Kingdom The UK government’s new border rules for dual British nationals, taking effect from 25 February 2026, are creating confusion, frustration and travel disruption for millions of people worldwide, particularly those living abroad who hold both British and another nationality. Critics say the changes have triggered panic among families and expats who now fear being unable to return home without proper documentation.
Under the revised policy, dual nationals must enter the UK using a valid British passport or carry a “certificate of entitlement” in their other passport proving their right of abode. This certificate which costs around £589 (approximately ₹72,000) has been widely criticised as expensive and burdensome, especially for older travellers, students and long‑term residents overseas.
Previously, many dual British citizens routinely travelled to the UK on their foreign passport alone, particularly if their British passport had expired or they had never obtained one. But with the UK’s Electronic Travel Authorisation (ETA) system now fully enforced, airlines and transport operators are expected to refuse boarding to those dual nationals who lack the required British documentation, even if they are legally citizens of the UK.
The policy has sparked strong backlash from rights advocates, legal experts and affected travellers who say it could discriminate against certain groups, including women whose names differ across passports due to marriage laws in countries like Greece and Spain. Many are scrambling to apply for British passports or certificates in a short time frame, creating stress and uncertainty about travel plans.
The UK Home Office defends the changes as part of an effort to enhance border security and streamline immigration controls, aligning travel documentation with systems used in countries such as the United States and Canada. However, opponents argue the implementation has been poorly communicated, leaving many dual nationals feeling caught off guard and stuck between costly requirements and disrupted travel.
Officials have urged travellers to check their passport status well before the deadline to avoid being denied boarding or facing delays at UK border control.
