"How in the Hell does "maal" finds out you have an American passport "

Well, given your argument, if no one finds out you have American passport, then, using your own argument, why the hell do you need dual citizenship? You just contradict yourself.

The reality is, those who can't invest in Nepal, especially the US-based NRNs, are often in the forefront demanding dual citizenship.

I support dual citizenship demand for some another reason. But I find the demand as a precondition for investment ridiculous.
