Hi
I holds valid H1 visa until Sep 2013.This is my first H1(I moved into H1 from F1).I am planing to apply for extension in this April 2013 as I am eligible for extension 6 months before expiration.I am planing for visa stamping in canda after extension may be in May or jun 2013 .My question is if got extension when it gonna start as my current H1 valid until Sep 2013? and If I go for stamping before sep 2013 ,does I get stamped onthe new H1 or how this procees could be?
I greatly appreciate if some one could help on this.
Thanks
Praveen.
