Hey Dude, Don't worry about your immigiration status right now as long as you are legal in this country and you haven't violated any laws you should be fine. I got married last year after dating for less than a year and I have my GC in less than 3 months I am fine and everything went smooth without paying an attorney any money. But i do really suggest that you think it over, marriage is nothing to be played with. I know a lot of immigrants come here and try to settle down or at least make their way to the citizenship through marriage and an immigiration officer knows that too. He/ she deals with those people in larger number everyday but as long as you think you will be with the woman you married till one of yours last breathe i say go for it and don't worry about all other stuff. Regarding immigiration papers you must have a solid proofs that you are guniune and your marriage is legitimate. Remember to provide those evidences it could be as little as a joint account, utilitiy bills and deeds or joint property, insurance policies or benificiafries don't worry about making babies right away you don't have to. Also do not rush into getting your GC as soon as you got married it will only raise a red flag so take your time, get married go for a honeymoon and start thinking about immigiration papers in 5-6 months. Ifyou are guniune and truley willing to commit for life with the woman that you married, I can hep you with the papers without any cost.
