I have my green card and was planning to apply for the citizenship of US.

I am aware that Nepal does not allow dual citizenship.

I would like to know what would be the consequences (in Nepalese administration) if I were to become American citizen.

Will I be able to live in Nepal and carry out administrative work as a nepali?

Will I have to surrender my Nepalese passport to the US government while getting the one from US?

Will the Nepalese government know if I have chosen the US citizenship?

Most probably if not certainly and if I have to surrender my Nepalese passport, I would have to get a tourist visa to stay in Nepal. But if I have to carry out administrative work in Nepal (e.g in offices like Malpot), will they find out and will it be a problem?

Thank to everyone who would answer to these questions sincerely. As you know it not easy to give up your nationality, but when you know all the benefits of carrying a US passport, the temptation becomes hard to resist. But it would be nice to know at what cost.
