this comment made me sad. i am a south asian national, i do have a canadian tourist visa and was hoping to go watch F1 in 2019 in Montreal. reading all of this is probably going to change that plan :/
The US is always a PITA, esp. after long international flights. One time they flagged me for "smuggling halogen headlights" or something and searched ALL of my stuff. Missed my LA-DC flight because of it. And I'm a white, clean-cut US citizen.
Do you bring back any food ?
(I had a undeclared box of cereal in my backpack)
