I truly agree with Amit..
And,they are here in  the United States, and are opening gas station,Hotels,restaurant, and obviously IT consultancy firm.At least,Nepalese are getting help from them no matter the work.So,we should try to learn something from them.Just imagine they are not our neighborhood  and realize how smart they are..only then you don't say Dhoti to them...We are saying Dhoti because we know their origin,what do they wear,what do they eat and every daily life activities. Forget about these things..We see them negatively even if you are getting help from them..So ,we need to respect them.
I don't think they can open Hotels,Restaurants,gas stations,and IT company/firm if they are not American or at least if they don't have permanent resident..So,just say they are Americans if we talk something about them in United States..
