if your hu*****and were found "misrepresentation" his applicaiton will be denied and no waiver availabe unless he has qualifying U.S. citizen or PR relatives. Better to do more to fight the "mispresentation" thing, such as:1) amended page 3 of I-485 (whether arrested in the past); 2) do a detailed affidavit explaining why answered "NO" both on the form and at the interview; 3) if possible, get a letter from your criminal attorney explaining what happened. Better to find an experienced immigration attorney.
