My wife is a us permanent residence card holder does she need any additional documentation before ...?

That is a good question, and I should probably give you a comprehensive answer.

If anybody applies for a job in the United States, he or she must be authorized to work. In order to avoid discrimination in our oh so concerned society, the question on whether she is a US citizen, a resident or an alien allowed to work is seen as a taboo before being hired. Therefore, at least in properly sized companies with a HR department, the application will only as her if she's "authorized to work."

Once hired, your wife will have to fill out USCIS for I-9, like anybody else who's being hired. On it there are 4 major fields:

1) US citizen

2) Non US-citizen national (people from American Samoa)

3) Lawful permanent resident (Green Card holder)

4) Non resident alien authorized to work.

So on this form, and only after being hired she has to tell them that she's a resident. If you google form I-9 and look at it (and I suggest you do!), there are 3 lists of accepted documents that proof the applicant's identity and her authorization to work: List A, List B, and List C.

List A lists documents that prove a person's identity and her permission to work, and on that list is the Green Card.

In layman's terms: all she need is her Green Card. She does not have to show her SSN card, which again in plain English means nobody cares what's written on it. Until I became a US citizen, I had my old Green Card stating "Not valid for work" on it. Didn't matter, as the number is always the same and I never needed to show it to anybody anyway as I had my Green Card.

Alternatively, instead of providing one document from List A (her Green Card) the applicant can also provide 1 document from List B and 1 document from List C.

List B lists documents that prove a person's identity, and the driver's license is on it. List C lists documents that proof authorization to work and the "unrestricted" SSN card is on that one.

So either your wife shows her Green Card, or, alternatively as to her choosing, she can show her driver's license and an unrestricted SSN card instead.

So back to your question: no, she doesn't need any additional documentation to start working. If she still has a SS Card stating "Valid with DHS authorization only" then the Green Card is the DHS authorization. As a Green Card holder she's eligible to get a card without that restriction on it, and I suggest she'll get one. The form is SS-5 and it's free of charge. Why? If she ever loses her Green Card (don't have her carry it around!) she can still apply for a new job with her driver's license and the unrestricted SSN card alone. No Green Card needed. That's why!

she should have applied for the social security number at the same time she was processed for her green card. if she doesn't have a SSN, she needs one. actually, if she has a two year conditional residence card, she can still legally work.

All she needs is the greencard ...2 or 10 years it makes no difference ..she can work

and a SSN of course

you have to provide lunch money

her social security card. She also cant be conditional, so make sure she can legally work with her visa. drivers license wouldnt hurt.
