Although immigration law does not require you to open a joint account with your spouse during the green card application process, you should strongly consider doing so. A joint account helps demonstrate to USCIS that your marriage is legitimate.
The interview is the last step before USCIS decides to approve or deny your application to adjust status. Both of you must attend the interview.
When you submit any application to USCIS, you must provide your actual physical address. During the application process, you may not move your application from one state to another just to increase the processing speed of your application.
As a U.S. citizen, your “Immediate Relatives” and certain other relatives may obtain a green card. For immigration purposes, the term “Immediate Relative” means only the following people: your spouse, your unmarried son or daughter under 21 years of age, and your parents if you are 21 years of age or older.
