Long story short, it's a complete quagmire, especially since you're bringing cross-border tax issues into play.

A small company that doesn't know much about compliance may be happy to call it "freelance", but any bigger company with a professional HR person is going to balk at it, because they want certainty they're compliant, e.g. no misclassification.

They're much more likely to be happy about it if you can stick a local LLC between you and them though.
