I would apply for naturalization without a second thought. That country you are worrying about is in the state of sleep paralysis. You want to do so many things, yet you can't make your move. Law makers are badly influenced by corrupt politicians, and what can you expect in such a country where rules are made as per their benefits? Bribery and exploitation begins the moment you land in that country, TIA personnel treat you differently if you hand them few hundreds than nothing. Anyway, there are ppl who won't talk bad things behind your back, even if your national status change from Nepalese to US.

It was good to read about first Nepalese billionaire in forbes listing, but who would understand how he achieved that,.. selling inverters??, evading taxes?? or through the businesses that he established in other nations? So those using his name as a shield to back their theory of 'opportunity in Nepal' need to zip their mouth for a moment and be realistic. Mostly, its run by money sent through foreign aid and wire transfers made by Nepalese living across the oceans. There is no electricity, rivers are turned to sewage, political instability, tremendous dependance on foreign aids, playground of foreign powers, failing juridical system, astronomical crime rates,  I wonder how businesses are running there and for any individual, I dunno but now having lived here in US for quite a while, I believe that place has become simply unbreathable for "many". Various NGO/INGO should be ashamed of not contributing enough to the country rather than leeching on donation/aid, sort of parasites, but few names like 'mahabir pun' are exceptions.

Go for it, why worry about others, when its about your life which you've to live by yourself?
