I recently visited Nepal and got my H1-B visa stamped in Kathmandu. The lady at the embassy only asked me if I had to pay anything for my H1-B petition (Answer: No). She asked me if I am getting my pay on time (Answer: Yes). She did not even look at any of the documents I had with me except for the I797 ( approval letter from CIS). That's about it. The whole interview lasted for about 2 minutes. Good luck.
