I am a UK citizen that lives in the US and I will (hopefully) also soon be a US citizen.
Shortly after that, I have to take a trip back to the UK. I'll be flying PVD-EWR-MAN-EWR-PVD.
I'm a little confused about which passport I would use at each point of my journey. Obviously by law I just enter and exit the US using my US passport and obviously I want to enter the UK using my UK passport, so I'm not sure which passport to use/show at each point, starting with booking the ticket at united.com.
I have read a few guides to traveling as a dual citizen online, but they all seem to offer slightly differing advice.
Are the any US/UK dual citizens on flyertalk who travel between the two countries regularly that could walk me thought their process?
Thanks.
You can either one at either portal, but you will need to carry both if you mix. UK will stamp your U.S., so if the US doesn't see a stamp,they may ask why.
They are used to dual nationals in this melting pot of a world.
Both of passports can be used with GEOS by the way.
