Wife is dual USC/UKC. We are planning on going to the US next year for three months. My wife's US passport will expire during that visit.
The plan was to renew her passport while there to avoid this money order nightmare we now have when renewing in the UK.
I always book trips to the US using our US passports to avoid ESTA questions, etc. when leaving the UK, but I presume I can't do that this time if her passport would expire before the return portion.
So I am wondering - book the trip using her UK passport, which doesn't expire for a long time. When we get to the UK airport they ask for ESTA we show US passport. Will that work?
Thanks!
