Fraudulent Documents?

Ok, here's the deal.

A friend of mine was in midst of changing her status to permanent resident. At first things looks great. However, in the process INS found one of her documents she submitted as fraudulent. An I-20 which contain a fake work permit stamps. The document obviously put a red flag on the application. Make things worst she knew that the document was fake from the start and admitted she submitted accidentally.

Now INS is asking her

1. Where did she get those documents?

2. Who issued it?

My question or should I say our question:

1. What's going to happen now since INS found she had a fraudulent document?

2. Will INS continue with the petition?

3. What are the chances INS found her guilty of using fake document and will she be deported right away?

4. Is there any relief as she didn't know much about it when she first got it?

Ok... I know that was a stupid mistake submitting the docs. What I want to know what's going to happen to her now.
