My ex-husband used me for a green card. We are divorced now. He got his conditional green card and is now applying for the permanent one using the i-751 waiver I assume. I reported him to immigration saying that he used me and a couple of affidavits from family/friends and a psychologist. What are the chances he will get his green card? He has pictures of us together, a couple of bills, bank statement while we were together (8 months)?
