I understand your thoughts but depends upon what kinda status you have in US. If you have GC and can go in and out all the time, you  really don't care where u live as there is no way after living in US you can go n live in Nepal forever. First the culture, you wilk feel like uncivilized seeing all those mysterious Nepali cultures and gods, second it's filthy out there, dusty narrow roads where you can't drive your car like you do in US, third you can't make the money that you make here, dollar is special I have burnt all the Rs 50 n Rs100 that I had from Nepal. It's has no value. Fourth, you can't get along with those Nepalese out there, they don't dress well, eat well, don't comb hair, no shower, trust me you don't wana hangout with those Nepalese out there, who has never been to west. Just stay here get married and make GC, there are so many gaule girls out of Kathmandu here in US who came through DV lottery, make them your wife for 3-4 yrs and kick dem out once you are on the safe side
