My friend has been in the U.S. for 3 years beyond the authorized stay. She is still in possession of a ten year B2 visa which was issued just before she came to the U.S. She has now married a U.S. citizen and has filed for adjustment of status and the case is pending. However, an emergency has developed in her family and they request her to go home to help. Can she travel back to her country? If yes, must she do anything special or can she just use her visa to return? If she does travel back to her country will her adjustment application be affected? If she does travel back to her country what may be the implications upon her return?
