Legal to work means they have a work permit. They don't necessary have to be green card holders or citizens. As long as they have a VALID work permit issued by DHS then they are legal to work. Also, like prev post check out what is acceptable on the I-9 form. Good luck!

Agree, this is a black-and-white issue, yes-or-no question. If they are citizens or permanent residents, they are allowed to work. There are other groups that require a work permit.

Just look at the I-9 form. It lays out exactly what you can and cannot accept as proof of authorization to work.

Hello all,
We are searching for a nanny and we would like to pay above board, withholding taxes. So, the nanny needs to be legal to work in the U.S. But, what exactly does this mean? That they have a social security card? That they are a citizen? What about a "resident"? And what about green card status?

It turns out that I don't know exactly what does make someone legal to work!

Thanks for any insight you can provide!
