Another thing to remember is... there's no case yet that anybody who travelled via TIA (who has nepalese as well as US citizenships) carrying US passport has been nabbed by the immigration for the purpose of persecuting.... There's no record as such.. afterall, as soon as they nab one such ex-nepali, it would have huge impact on for Nepal and the Govt. - both monetary reason as well as the hassle Nepalese govt will have to deal with US diplomatic pressure. This is not going to happen. Be assured.. so simply go to nepal carrying your US passport.. pay the required visa fees and Nepal is happy to take that visa fees plus your nepalese relatives are also happy to get some free gifts from you. And additionally you would be contributing to your former country anyways by spending some green dollars there in Nepal..

Now if your borthers and bahujus are trying to blackmail you so as not to give you fare share of your parental properties... Tell them to think twice...  because as soon as they go and report against you about your dual citizenship, Nepal will have to take action against you by throwing you into jail for 20 years.. ask your relatives if they want you to rot in the jail.
