I was born in Canada (Toronto) so I never usually get hassled by the Canadian customs folks, but I often times get asked from US immigration officers on whether I'm actually commuting, operating a flight or deadheading. I'm guessing they're fishing for confirmation on why I'm in uniform if I'm not with any of the other crewmembers . The last time I flew to Toronto after being released in domocilie, I non-revved to YYZ and on the way back (they have US Customs & Immigration officers in the airport in Toronto in a quarantined US departure terminal) had to justify why I was in uniform since I had not operate any flights to or from YYZ, nor was I a deadhead crewmemeber. Then she asked me how I could be commuting if I was supposedely a U.S. resident? "Lady I'm a permanent resident of the U.S. who was born in Canada that left straight from work to visit my folks in Toronto in my uniform!"...well that's what I was thinking...didn't actually say that. I stood there I silence, and I think we both finally sensed that this was a futile converstation and she just let me go on my way.
