Permanent Resident Card?

What a hogwash, all of it!

First, at the time one applies for naturalization, the Green Card, has to be valid for at least another 6 months. If her N-400 was accepted with a shorter duration, she may get lucky, or the I.O. will ask her to fill out an I-90 first.

Second, a Green Card holder's status doesn't expire, even if the document, the Green Card expires.

Finally, a Green Card holder doesn't even have to show her Green Card for work an I-9 form purposes, EVER. She can fulfill the document requirements by showing her driver's license and unrestricted SS card, which she should have. If she doesn't have one, she can get one tomorrow! Have her look at the 3 lists of accepted documents at the bottom of the I-9 form.
