A friend of mine just got his US citizenship last week. He became a dual citizen. He then left the US without a US passport with the intent to apply for his US passport at a US embassy overseas. Is that possible?
As far as I know, he had to leave the US with a US passport (even if he is a dual citizen) and that it is actually the law that you have to be in possession of a US passport when you leave the US (even if you are a dual citizen).
So will he be asked at the US embassy why and how he left the US without a US passport?
