ear Sajha experts I  graduated in May 2008 . Right after the graduation i am sticking with Dhoti consultancy and jobless yet. Now I am planning to go  to Ph. D. college in coming fall 2009 and my OPT expires in June 2009. As soon as I get I20 for fall 2009 I am going to nepal , may be in April. Do you think I have to go the embassy again for F1 stamping if my F1 visa is valid till 2011?. In this case my I20 and visa are from diferent universities. Moreover I am in OPT for one year. I am so much worried. Your opinion/ suggestion is highly appreciated.
