I came to US in 2011 with a 2 year F1 visa to study MS in a US university but after few months transferred to another US school for PhD. So, I got my SEVIS record transferred to the new school and I got new I-20. My F1 visa, which has the name of the previous school in the stamp, expired in 2013. My question is that if I go to India now to renew my F1 visa, can there be any trouble in getting it? My current university issued me I-20 which is valid till the end of 2016. Any help or suggestion will be much appreciated.
