> Nobody is an alien in this country [USA] ...

There may be some terminology or crossed wires here. For example I have a US government issued card that literally says on it that I am a "resident alien", and is the reason I can be in the US. When filling out forms, such as employment related, or opening a bank account there will be somewhere that I have to say (again literally) that I am an alien. Also the government can revoke this at any point for any reason they deem fit, there is no right of appeal, nor do they even have to tell me why.

This is at least one way that someone is an alien in this country, using US government terminology.
