My fiancé has both an American and an Australian passport. We are currently in the USA, planning to fly out next week, but his US passport expires in 2.5 months. He usually travels on his AUS passport (valid for 9 more years) and will be entering Europe on his AUS passport.
We plan to be back in the USA the second week of March.
Does anyone know if he will have an issue leaving the USA with his US passport expiring, even though he has his AUS passport?
