What is going to happen to me if he is divorcing and I do not even have a temporary green card?

Then you do not get a green card if the marriage is falling apart even before the interview. You will need to go back to your home country because you will not be eligible to change or adjust status through any other way if you came to the US on a fiance visa.

Numerous factors will have to be considered before your attorney could tell you how to proceed in this case. Many, if not most, of these factors are so personal in nature that no self-respecting professional would engage in discussing them on an open forum. Find an immigration attorney, the sooner the better. Look for a specialist, not an attorney who takes immigration clients between real-estate closings. Ask your friends for a referral, or call the American Immigration Lawyers Association.

Generally, in this situation, you need tile form I-485 and the other related forms and supporting documents. Feel free to contact me if you would like the assistance of a board certified immigration lawyer.

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.
