I have H1B valid till Aug2016. I am currently in India. My wife has applied for MS and get has got admission. We applied as international student to get I20 for loan purpose. I might travel to USA soon. My question is can my wife join university with H4 VISA even though she has been marked as international student with I20 issued. Also, as my visa expires soon, my company will apply for extension. So my question is can she join the course with receipt notice of visa extension filled.
