oh man  u r abt to get into a long long process. first get married and then go with a lawyer to file for the permanent residency. u gotta take a interview and then get the card with 2 yrs validity and after that u again need to file for the 10 yrs one. Between these there are lots n lots of other process. chk the USCIS website for all the details. Best of luck wid you green card processing
