So I loved MFF and really enjoyed the dealer's den. I'm thinking of bringing a buncha mini plushes and mini sculpts to sell (along with the SSP-Comics prints) and maybe other stuff.

But I'm not super sure how to do this since I'm Canadian. I don't wanna get denied entry. Anyone do these cons in america and are international know what you need to do to not piss off the border police? I honestly have no idea what applications I need and how much it will all cost.
