Thanks everyone.

But when I enter nepal with the american passport and obtain a tourist visa in the airport, will they not check to see why a nepali guy has a foreign passport and if he still holds the nepali citizenship (just out of suspicion, or curiosity or even jealousy)? Will they not send my information to the office that takes care of "nagarikta" in Nepal?

What are the chances of these things happening, and has anyone already had this kind of experience or anything relating to it?

Thanks again.
