You will get green card eventually, but you have to pass many obstacles. If you are not marrying for paper porpose, then, you would overcome those obstables. Otherwise, you would fall sooner or later on those obstacles.

       First, get marry, then get lawyer, then file the case in uscis, then, after two years, you would get first interview, if you are really hunband and wife, then you will pass this interview.

          If you are not real wife-husband and never spent a month together ( means share a bed), then uscis officer would definitely neil you down. They would ask all kinds of questionair including private moments of wife and husband !!!! and, they would except same answer from both of you. In this case, they take interview at same time, but differetn room and later on sychronize these answers.

    If you pass this interview, they may call you for another interview after 2 or three years. So, its not a cup of tea !!!!!
