My understanding is for a US employee, the employer is supposed to confirm eligibility to work in the first 3 days of employment. Some form of government id plus a social security card or a passport or something like that. IRS form I-9
Otoh, if these positions are independent contractors, form I-9 isn't required. Just a tax id for reporting purposes.
I would imagine whoever is hosting the laptops may be authorized to work in the US and could also be convinced to provide identity documentation. I think there's a lot of borrowing of documentation by immigrants/migrants who are not authorized to work in the US; so there's probably a marketplace somewhere too.
