In respect to Bhavna's question about whether I have acquired and/or ever thought about acquiring citizenship in Nepal, my clear and unequivocal reply is "no", to which I hasten to add that the thought never once crossed my mind.
In turn, I ask why would a foreigner/expat who enjoys benefits and advantages derived from holding a foreign passport(s) be willing to consider giving up those benefits/advantages to become Nepalese?
The Constitution of Nepal regulates provisions for Nepalese nationality in Articles 8, 9 and 10. And under that Constitution as it stands, the law places a total prohibition on dual nationality in Nepal. The Constitution and Nepalese laws until and unless amended, do not permit anybody dual or multiple citizenships.
So, what is the process like for those expats who wish to do so....? I don't know is my honest answer.
What are the benefits of Nepalese citizenship, I pass.
Let me just point out that dual citizenship is not a new concept. Many countries in the world have this provision, notably the USA, UK, Australia, Switzerland, and over 20 countries in Africa. Some countries make no distinction between regular and/or dual citizenships.
But if Nepal is not on the list, how many foreigners/expats would be prepared to run the risk of having their foreign passport revoked and/or lose all benefits/advantages in the process? I can't imagine there would be too many!
On the question of allowing or not allowing people of nepalese origin to have dual/multiple citizenship, the large number of so-called Non-Residents or "NRN", that is a totally different matter. I abstain to comment here. Too many "pros" and "cons" and let's be honest, the subject is too sensitive in Nepal. As a foreigner and friend of Nepal, I must pass on this one too!
Let me conclude with this general comment: over a 20 year period, I cannot start to count the number of my nepalese friends or acquaintances who told me they wanted to go the other way, namely ready and most willing to leave Nepal, go abroad (not just to work in the Gulf or middle east type of work, or to study) but sincere in their desire to "get a foreign passport" and live overseas to the extent that they can find a host foreign country which will let them in, find work there, etc.
