Allan:
I am a Canadian married to a British citizen. My wife has a UK passport. In 2012 (the last time we visited the USA) we were crossing the border at Niagara Falls into New York.
My wife, being British, had to go to the US Immigration hut for processing into the US.
Whilst sitting in a hot, stuffy (in January, no doubt!) building for a very long time, my wife needed to get some air. She stepped outside the doors and stood there within view of the interior.
Shortly afterwards, a US Homeland Security goon came up to her from the exterior with his gun in his hand yelling at her to get back inside.
I suppose there must be a lot of middle-aged female British terrorists just itching to walk into Amurica from Canada by surrendering their passports to US Immigration.
We decided at that moment we were not going to spend any of our hard-earned money in the US again.
