F2B case which was approved and sent to NVC and waiting for priority date to become current. now my father i.e., petitioner, has changed the address, intimation of which was sent to NVC at there email address. We received automatic machine response email. but no other email has been received by us which says your address has been changed in record after 3 weeks also.
Was emailing to NVC was right thing done by us and does NVC reply back to such email or not ?
