The United States are not the only business destination to tighten its immigration rules. And unlike the US, the UK has been quick to act, with a logic that may escape some travellers. Since 25 February, travellers with dual nationality - including British nationality - have been required to present a British passport, which was not required until this week, when their other passport was accepted.
Another option: the new digital clearance certificate, available for the modest sum of €676 (£589). That's almost seven times more expensive than the British passport. Add to that the processing time and the "sudden" introduction of the new system, and you have some very complex situations for many people. Particularly for dual nationals who are not currently in the UK.
And since the measure seems to defy all rationality, British nationals - including dual nationals - are not eligible for the simple Electronic Authorisation (ETA) required for foreign travellers...
According to the BBC, based on the 2021 census, around 1.2 million people will be affected across the Channel, counting only UK residents.
