The UK is implementing new entry requirements for British dual nationals effective February 25, 2026. This change affects anyone who holds British citizenship alongside another nationality and travels to the UK.
The core rule: dual nationals must now use their British passport to enter the UK, even if they hold another valid passport. This aligns with existing EU practice and is part of the UK's broader immigration framework. If you're a dual national living abroad or planning to visit, you'll need to ensure your British passport is valid and up to date before this date.
Dual nationals must use their British passport to enter the UK starting February 25, 2026.
What to do now: check your British passport expiration date. If it expires before or shortly after February 25, 2026, renew it immediately—processing times can run 6–8 weeks. When you travel, present your British passport at UK borders, not your other nationality's document. If you've let your British passport lapse, apply for a renewal before the deadline.
