"Comes to the US on fellowship or scholarship and .................." Of they feel interested they will go back if not they wont... they dont have obligation to back if they dont want to. After all it's a matter of personal choice. "Well established in the US and can talk.................." There is no harm in expressing opinion about Nepal and other country. Why should they help do anything about corruption or poverty ? Socio-political culture of the country will not let them help anyway. "Have Americanized children......................." Children follow the attitudes and cultures of the country where they grow up. I dont think that a child that has grown up in Japan will end up having the social and cultural values of Brazil or a child that has grown up in Nigeria will having the social and cultural attitudes of Russia. "Wants duel citizenship..................." Well, India has opened up and granted its citizens to have duel citizenships. Both th US and Canada has no problem with the matter. Why should we. "Wife still cooks, does the dishes................" Infact both husband and wife do to each other when necessary. "Probably married to an Amrican chic.................." That's a very personal decision..why should anyone care about it ? In fact, if someone is really worried about nepali values and customs, it's better they live and stay in Nepal not in the west. Live in the west with Nepali attitude, you'll have no success of intregrating with the mainstream society where you are living.
