The Immigration Service looks very carefully at all marriage-based green card applications. More likely than not, you will have very hard time trying to convince them that your marriage is real despite the fact that you do not live together. If you can maintain lawful visa status until the time when your fiancee could join you in one home, it is better to marry now but hold off filing for a green card until that later time. Moreover, if you file for a green card soon after the marriage, USCIS will give you a 2-year, conditional green card. If you marriage does not survive for 2 years, you will lose your green card; otherwise, you and your wife would have to file another petition, pay the fee, and go through an interview to be approved for a permanent green card. But, if you file for a green card after 2 years of marriage, you will get a permanent green card without this second stage.
