How do I prove that I entered the marriage in good faith?

Your question requires an attorney consultation. It is not a simple question that can be answered on this type of forum. There are many factors that would need to be considered and evaluated. I strongly suggest that you contact an experienced immigration attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. He/she would then be in a better position to analyze your case and advise you of your options.

The best suggestion is if you do not already have one, retain an attorney. These are not easy cases and the fact that you have a denial means be prepared for an uphill battle. Any experienced Immigration Attorney should be able to assist as Immigration is Federal law. At the minimum, pay for a consultation to be guided in the right direction. Many, including myself, will even do these over the telephone to accommodate clients.

I strongly recommend that you consult with an Immigration Attorney Immediately. In this 30 day period, you have your best chance to get the petition approved once it is denied it will be very hard to fix it. This is the time to the best most well organized package together you can. You will need cover letters, statements and documents to evidence your relationship. Please take this very seriously if you really want to get your green card.
