What contract should I conclude with an American company if I am a freelancer?

Question

Distant work

They offer me wc2, but for this you need to be a US citizen or a green card. I am in Russia.

Answer 1

SSN and work permit are enough))
wc* are irrelevant to you, as long as you cannot be a US Employee
only as a Contractor (if they charged wc2 right away, then a surprise may await them with the contractor, most likely, the accountant will not want to contact)

Answer 2

Which contract to choose for remote work from the US or CIS?
