While correct, it’s not clear at what level Daniel has been “banned“. He was denied an ESTA and told to get a visa, but that hasn’t been denied (yet?). Canadians need neither, so he might be cool if he showed up at a PoE, or maybe not.

And a visa/ESTA isn’t required for most Europeans arriving at a land Port of Entry, so who knows what would happen then. But they do ask more questions when you don’t have an ESTA.

I guess if the USA wanted to arrest him, they would’ve been very fast at granting a visa.
