You need to hire an immigration attorney. I edited the practice area to include deportation and immigration. You seem to indicate that your husband is not facing any criminal charges, if this is not true, you should also hire a criminal attorney. Good luck.
You failed to mention your status in the U.S. Considering you are a U.S. citizen, after marriage you can file a relative petition. When it gets approved your husband will be able to file his application for adjustment of status. Please remember that removal proceedings are very complex and you would need an experienced immigration attorney to represent your husband during this process. Your soon to be husband has good chances of avoiding deportation if he doesn't have other criminal problems.
This is really an immigration question. Without any criminal convictions most of us criminal attorneys do not know the immigration system well enough to answer this and we need more facts. Consult with an immigration attorney to help strategize for him. Good luck.
I agree talk with an immigration attorney.
