My wife surrendered her green card using form I-407 at a foreign consulate 5 weeks ago. Her family is angry with her and now she is having second thoughts and wants to change her decision and get the green card back. She is blaming me for her decision and saying that I forced her to return the green card. But the fact is she was interviewed by a consular officer and herself signed and submitted I-407 and her green card to consular officer. Is it possible for her to get the same green card back if she blames me and says that it was not her own, free decision? If so, how?
