Does my fiance still have a chance to fix his papers after drug charges? 2 Answers as of January 16, 2012

I've been with my fiance for 5 years and we have two daughters together. However, the relationship went horribly wrong last and we got in an argument that resulted to me calling police. I even accused him of hitting me though it wasn't true. I believe those charges were dropped already, only thing, he did plead guilty to the drug charges. It was the main reason for the argument in the first place. I caught him doing drugs and it bothered me so much. I love and still want to marry him but I am wondering whether he can still fix his papers? Additionally, if he came back following being deported, does that ruin his chances? I think he has a very good reason for coming back. Our youngest daughter is going to have an open heart surgery and he just need to be there with us.
