(1)When I leave US port, should I turn in my currently valid I-94 of H-4 or the expired I-94 of F-2 obtained when I got in US five years ago?
(2)Can I still get the new I-94 for H-4 status when I come back and apply for new I-94?
(3) Do I need to show USCIS at US port any other documents except AP for the I-94 for H-4 or 485 pending?
Thanks a lot.
