Thanks for the info. Just had my interview today and had similar documents as you. The interviewer only asked for my passport and i-797a. He asked whole bunch of questions about my job and employer to know what exactly i did. but the whole ordeal was over in ~5 minutes.

i have a question regarding labor permit stamping in tahachal. do you need to buy insurance from nepali insurance company in order to get the stamping? i already have my insurance from my employer in the us.
