Hi, my brother is F1 student in the U.S. , doing adjustment of status via sibling sponsor (f4). He submitted I-485 in Jan, 2019, got fingerprint complete. He will graduate in August 2019. He's waiting for EAD. Should he apply EAD visa OPT optical training also? Is he o.k. to wait in the US pending I-485 like married cases or he has to maintain his F-1, OPT status? Any of you in similar situation? Thank you so much.
