Hi friends, my visa is expiring this june 30 2006, and i am doing OPT right now so i believe that my visa status still remains F-1 (i have valid I-20 its until 2007), but I need to visit Canada in august and I want to come back to US and finish my OPT. To come back to US again do I need to obtain a visa from Nepal (i am guessing that i will require F-1 visa again) Any suggestion/s please.
