My G.C holder Friend who applied i-130 in April , which was four month earlier than mine has still not received any form . I want to go to Nepal this December for two months , is it OK ?? Some say it will at least take 6 months to get a review or any letter from them. Any idea.??? and also i have to change my address a couple of months be-four i go right ???
