What does it mean to "leave" a country on a passport (specifically, the US)?
There are a bazillion questions here from dual citizens asking about how to use their passports when travelling, and the consensus seems to be: enter and leave the US on your US passport, enter & leave other country on your other country passport. What does "leave" mean in this context? I haven't travelled out of the US since 2002, and don't remember what the procedure was then. Is there some kind of immigration checkpoint before you get on your outgoing plane? Or does it just mean the passport you show when you check in at the airline?
Details: I'm a New Zealand citizen long-term resident in the US with a Green Card; but I also have a British passport which I've never used. I want to go to Europe. So, do I show NZ passport at the counter when I "leave", Brit one at European immigration, Brit one when I check back in to come home to the US (ie "leave" Europe), and NZ one when I get to US immigration? Won't the European airline want to see my NZ one to check that I'm allowed back into the US?
