I am a dual citizen. I have both a US passport and a non-US passport. I live in the US.
My US passport is currently being processed for renewal. I am unsure whether I will receive my passport in time for a trip that I have scheduled.
Could I use my non-US passport to leave the US and return? I have never entered the US with my non-US passport.
There is no immigration leaving the US but I still need to scan my passport for ticketing. Will the airline refuse me a ticket?
I know that in this situation returning with a non-US passport can be problematic as well, but will I be able to leave at all?
Note that I am traveling to a country which neither of my passports are from.
