[h=1][/h] Hi I am doing a 6 months cerification course in US on F1 visa and i have been granted a 6 month visa for that.. After that because of some genuine reasons i want to extend my stay in US for additional 6 months..I also have a 10 year Visitor visa... So my question is 1. After my student visa expires will i be allowed to stay in US for additional 6 months on visitor's visa..or 2. Will i have to come back to my home country and go again to US on visitor's visa.. If that is so then after a gap of how much time can i again leave to US on a visitor visa after coming back to my home country.. or 3. geting F1 visa means expired tourist visa and i will have to come back to my country and reapply for a new tourist visa. Thank you
