Intrepid,

If you are planning to get stamped in Nepal make sure that you have enough paperwork from current employer.I heard that US Embassy asks for photo of current workplace..thats completely non relevent

Most of the Dhoti consultacy gives you a H1packet before going back to native country for stamping.That H1 packet contains their registration and other other documents.

Also some friends were telling that US embassy have checklist for H1b stamping.
