I encourage you to read those articles!

I only linked you cases where people had valid legal visas. What are you expecting me to find?

Canadian entered to work without a valid visa, as the article states, her visa had been revoked in November and she was aware of this - she should have arranged a visa at an overseas consulate before crossing the border

German backpacker was detained for hours not days

German tattoo artist arrived with a tourist visa with supplies for working

German fiancé — not a normal tourist case but yes this seems to have been a mistake by CPB

Again, the conditions and duration of detention are absurd but normal tourists are not being detained for days

> Canadian entered to work without a valid visa, as the article states, her visa had been revoked in November and she was aware of this - she should have arranged a visa at an overseas consulate before crossing the border

I'm not seeing that.

>After a long interrogation, the officer told me it seemed “shady” and that my visa hadn’t been properly processed. He claimed I also couldn’t work for a company in the US that made use of hemp – one of the beverage ingredients. He revoked my visa, and told me I could still work for the company from Canada

“ He revoked my visa, and told me I could still work for the company from Canada, but if I wanted to return to the US, I would need to reapply.”
