My US passport expired in february and I am flying to the US in 2 weeks.
I have dual citizenship, which means I also have a Danish passport, but my application for ESTA was denied since I technically hold US citizenship - although my residency is currently in Europe.
I will only be in the US for a memorial for 4 days.
What should I do? Can I travel on the expired US passport?
In Denmark it is not easy to get a passport renewal done quickly as the consulate is completely backed up and almost impossible to get in touch with.
