I take it you don't have to go through US immigration. (The USofA is a country nearly entirely populated by immigrants anyway).
I think most of the problem is that US immigration is getting rediculous. My wife was coming to join me in Belize and they wouldn't let her catch her connecting flight in Miami because she had no return ticket! She was coming for 9 months from the UK to a commonweatlth country and not leaving the airport terminal - what business is it of the US government if she is using one way tickets since we didn't know my end of tour date (I was there with the British Army).
And lordy, try and get in on a Visa to learn to fly! I know that it is sensitive, but I was a British Army helicopter pilot, having spent time with US forces in Kosovo, Macedonia and Bosnia. was it really necessary to make me sit in a room for 2 hours while they phoned my flight school and asked if they had heard of me?
Was it Brazil who fingerprinted and photographed the US crew coming in, and look what response they got!
No-one is denying you your right to defend your borders, it just seems that every other country manages to do it without making you jump through hoops for hours.
