Yo Dudes Hello Chaps, after living here for 15 years the missus and I finally had our citizenship interviews and will soon become US Citizens (yippee !) . we want to retain our old UK passports for travel in Europe (hopefully shorter border patrol lines) . I've been trying to find out the most unproblematic way of travelling with 2 passports to/from US/UK but have been unable to find a definitive answer anywhere. I know that we must enter and leave on the US passports and since US passport holders can visit the UK for 90 days travel to the UK is no issue. However it has been suggested that is it better to show the UK passport at checkin as the country you are going to rather than the passport from the country you are exiting, but show US passport to border officials, or could one show both of them ? and what about the advanced passenger information that the airlines ask for, would entering the US passport details at this point and the UK passport at check-in really blow their minds ?
