Hi, just curious about this I-194 card. I have received my second waiver (5 year), and am going to the US in May for a work conference. I went to the US once before when I had my first 1 year waiver, but didn't require or get an I-194 card stapled to my passport. Is this something new? I handed the customs office my passport and waiver, he just asked me what the waiver was for, then then asked me to line up with some other people. They sent us to a room and had the dogs sniff our bags. Would it make sense for me to visit the wicket at YYC and get the card stapled to my passport before I go on my trip?
Also, I am flying through YYZ on my way to Florida, and I assume I will be clearing customs there. I have an hour and 40 minutes between flights. Should I re-book with a later connecting flight to give myself more time in case?
