Dear sajha sathi haru, I am here in US as F1. My son's F2 visa going to expire this year in August. We all family planned to go to Nepal in May 2010 after my spring class finish.In this situation, if we go to Nepal at around May 16,10 and return back say June 16, my son still will have 1 and half month visa left to expire. In this cicumtances, do I need to apply visa for my son to come back or not ? OR  Are they allow us to come here without problem ? Your honest sugesstion would be appreciated. Thank you in advance..
