If she is in H1 than there is no problem. If she already had H1B stamp in her passport than she just has to go nepal and get married in temple which is very easy and fast and very next day go to Nagarpalika to register for marraige take few photographs with you. They will give you certificates right away. and than go to babamahal to translate it into english they will do it same day if yo give them Rs 500 ghus otherwise next day. On the mean time apply for visa you don't need marriage certificate to apply for visa so you can do this same day but you need certificates and few wedding photos for interview. If she has h1b stamp than she don't need to go to embassy otherwise both have to go to get visa for both couple that's it. Take a letter form employer too and police report will be plus for him. H4 visa is the easiest visa to get and less chance of rejection. But think one thing what he will do after come to US . He can't work. But can join school. Staying in home alone whole day will be another frustraing... hope this will help to your friend. Saan Dai
