Though a lot of people in the USA normally say "I don't care about NRNA"--but probably it is time to thank Upendra Mahato, for what he is doing will be helping these US based NRNs immensely.

Sure, you can fake your way into selling the land, and may even get away from it. You can also probably get the money out of the country. But the best way is legal way. Join some organization, lobby for your right, and you can legally own and sell property in Nepal.

It will also probably make you pause for a while, and you may want to invest in Nepal, and take only your profit out of Nepal. Or who knows, you may decide to live there once you realise that the Maoists  also no longer want to wage people's war anymore.

So, friends, join NRNA, get your rights, and do things legally. Interestingly, most of the NRNA leaders I met actually hold Nepali nationality even though they are living abroad for decades, and some are only holding greencard (consciously chose not to take US citizenship).
