After I get married, I am planning to get my FLR in my maiden name, and then change the name in my passport after I'm married. (I don't want to risk having my fiance visa expire while I'm waiting for the American Embassy to change the name on my passport.)
Once I get the name change amendment on the US passport, do I have to do anything about the fact that my FLR stamp will be in my maiden name? I've contacted the Home Office, but they seem to be confused, because apparently when a British citizen amends her passport to show her married name, she gets a brand new passport, (but it's called an amended passport because the expiration date is the same). So the Home Office keeps telling me about transfering my visa from one passport to another. I have no intention of getting a new US passport; the one I have doesn't expire for almost 9 years.
