British dual nationals: have you been prevented from travelling to the UK?
From 25 February, UK international carriers must verify all passengers have valid permission or status to enter the UK, affecting British dual nationals without proper documentation.
Will British dual nationals really be forced to have a valid UK passport from February 25th?
British dual nationals risk being denied entry after Feb 25, 2026, if they arrive without a valid UK passport or certificate when the ETA tolerance ends.
