I have valid H1b VISA till August 2016 and my wife HAS h4 dependent VISA for the same time. I am currently in India. I might get chance to travel by End of Jan or Feb 2016. My wife applied to certain colleges in USA for MS in Computer Engineering for Winter 2016 semester. My question is can she travel before me with H4 VISA. We have not applied F1 VISA for her. We thought once we both are in USA we will apply for change of status in USA.
Is it ok if my wife travels before me on H4 VISA?
Also, If she does not join Winter semester and decides to join in Fall, can she join if her H4 VISA extension is applied and pending.
