I came to US in 2007 on F1 visa. I changed to H1 in 2010 through Change of Status when I got a job here. After that I again joined PhD last year and changed to F1 through a Change of Status.
I have never been to India since 2007. When I go, will I need to apply for F1 visa from scratch or am I eligible to renew visa? Is there an easier procedure to get the visa from the US itself?
Would I be at a disadvantage in the visa interview because I changed to H1 in between?
