Getting Tax ID (EIN)
As a non-U.S. citizen without a social security number, you would not be able to obtain an EIN for yourself individually. However, you would be able to register a C-Corporation or LLC in the United States without having to be a resident here or obtaining a social security number. Once you have your entity registered as an active business with one of the states, the entity may then apply and receive an EIN.
Alternatively, its possible to obtain an EIN for your Chinese corporation directly, without registering any new entities, and with you being the company representative (no SSN is needed in that case as well).
