I am married to an American citizen and I am currently on F-1 visa, but we are going to apply for green card this month or next month, depending on when my parents in law get their income tax return. However, due to financial reason, we are thinking of moving to my husband's parents' house who is our joint sponsor in another state. (I'm thinking about taking a leave of absence this August.) My questions are: 1. Is it ok to move/change address before receiving NOA? (We want to apply before moving because we have a lot of proof that we are living here, but if we apply from my husband's parents' house we won't have lease or bills with our names.) 2. If we move, will we still need to establish proof that we are living in the parents' house and if so what can we prepare in our case?
