Do you think those indian students or H1B in US pay their tax in India? There is huge differences in consequences about not paying taxes in India and US, and that is too for students and workers.
So I think it is not the same thing. They are benefiting a lot because of this tax compensation.

Whatsoever, I am not emphasizing Nepalese Gov. to make similar tax treaties with US. Obviously, this should not be their priority now.
