I was told by a friend that when returning from Nepal with H1B visa in your passport, you need to have some short of approval from labor department (Shram Bibhag) of Nepal in your passport or H1B paper works. If you do not have it then they might not let you board the plane.

Does anyone know the truth? Has anyone come back from Nepal with H1B visa and had these kind of issue? What are the requirements from Nepal Government for H1B visa, if there are any?
