This waiting is frustating. Same things happened to me. It was on 2009 when I applied for stamping H1 B visa in US embassy, kathmandu. VO asked additional docs with Blue paper. I was working for Indian consultancey. They took time 1 and half month for sending those docs. It was lot of documents. And I submitted those docs to US Embassy. They approved it after a month. so it was 2.5 months waiting. So I think if you have all documents your visa will get approved\stamped. only thing it is time consuming. so while you are in Nepal enjoy that time with frens n family. I wish you all the best.
