I had H1B visa and got expired on 22-Sep-2011. During my visa validity i did not travel to US due to some reasons. So my questions are: 1) Is there any way that I can renew my expired H1B visa. If so what is the procedure for the same.? 2) Will I come under H1B Cap Exempt? 3) Do i need new employer to file petition? 4) If at all i get visa then what would be the validity?
