Guys, I was just wondering if we could file an online application for F1 visa interview to USA  and pay the required fee online with credit card. I am going to Nepal in Dec and I need to get new visa when I come back. I looked through the US embassy website but I couldnot really find out if we can pay the application fee online. Since I will be there for a short time I fear that I might not get early date for visa interview if I apply after I reach Nepal. Your inputs will be highly appreciated...thanks!!
