I am also going to Nepal to get my H1-B visa. Based on threads I have been following in this forum it looks like it is going to be a peak time during the month of December. I have three weeks between Dec. 1 and Dec. 23 to get the appointment and visa. Do you guys think this is enough time? Do the embassy give any priority for H1-B over F1 as they have to take a vacation from their work? Is there any form of priority appointment?
