congratulation  on your second class citizenship. Time will tell buddy just wait. Nothing wrong with getting new one, jani jani kana giving up is very sentimental and sin to some people that's all. Join the lobby NRN and tell how much money , skill you can bring in poor  country with dual citizenships, go ahead, measure it up with price skill but that is not the point. THE POINT IS YOU GAVE UP PRICELESS ITEM IN FIRST PLACE WITH FULL CONSCIENCE WITHOUT ANYBODY FORCING INTO IT.
wish you the best, you can remain be nepali no problem, people do it for different reasons I totally got it.
