I am a US Citizen, but after moving to England and marrying my British husband I acquired a UK one as well. We had a son in England, and were able to get him both UK and US citizenship. My son and I both now have two passports. We have recently moved to the states, and my husband now has a green card. I am nervous for our first trip back to England. What passport do I use? If the US finds out I have dual, and my husband is here on a green card can they deny us entry?
As far as I am aware I am supposed to use my Uk to enter England, and my US to enter the States. Do they not wonder where you have gone when you dont use the same to check in somewhere else? Also it states to use the correct passport when leaving, how does this get notified, is it when you check it to the airline? Any help would be greatly appreciated.
