First one have to get married. You have to go to county circuit court and get married. Than go to your lawyer and filled up the firms. Yuo have to apply for the work authorization too. You will get ur work authorization card by a month sometime u may get ur green card earler than work authorization. Once u mail your petition you wil recieve a letter saying to go to nearest ins office to get ur fingerpirnts. Once you are done with that you will recieve a interview notice which should take no longer than 3-4 months. You will ask to have a medical checkup. You have to prepare your other documents too like valid passport(very important, let u know why?) you have to have a min. us household income. You have to have a recent taz document just in case. After all this Pray to god and go for interview. They won;t be hard on you but will try to ask every detail like where, how and when u meet? what your otherhalf likes or dislikes and eachtothers so n so. Well i was saying valid passport cuz they will stamp on it stating that u are us residence or if u have a expired one they won't do that cuz sometime getting G- card takes time even ur case is approved. I know all of this cuz, It have happened to person whom i helped to get G- card. Thats why i am kicking my ass now why i did that stupidity he he he. Your G-card will be valid for 2 years n u have to renew it after that for a year. After a completion of 3rd year u can apply for ur citizenship. wish u a good luck sir.
