Divorce after Green Card

[muchalucha]

Hi,
My relative from Pakistan got married to a US citizen. After two and a half years of marriage (she lived in Pakistan for the first two years waiting for the GC), they are getting a divorce. It's been one of those messy divorces where both parties were unhappy with each other.
She is now back in Pakistan. Her husband says that he has cancelled her Green Card stating that she fraudulently married him for the Green Card.

First, is it possible for him to cancel her GC?

Second, is there anyway I can verify by calling some government agency to find out if it has really been cancelled? She has sent me her GC info.

Thanks for your help.

I don't quite follow you... so your relative was waiting in Pakistan for her GC for the first two years... and then? Did she come to US and get her actual card? If yes, then is it a conditional GC? If she has a conditional GC, it will be valid only for a couple of years and to get an unconditional one, she will have to file I-751 along with her husband to remove the conditions - thus, if divorce happens before the I-751 is filed, she's going to lose her GC status after the conditional GC expires.

However, if she received an unconditional GC (ie she had completed 2 yrs of marriage before getting approved for GC), then she wont lose her GC.

HTH, USC
