"You want to come back to your old home when you want and go back to your new home when you feel like. "

Yes this is what they want. What is your problem? As long as they don't give up their Nepali citizenship they are citizens of Nepal.

Let's give true freedom to make a living to all of our citizens. This should be a Right of all Nepali citizens that as long as they do not willingly give up their Nepali citizenship they should have the d** Nepali citizenship.

We should not try to make chance of our fellow citizen to make a living less than those of other countries. Let us not be shortsighted. These people belong to our culture they are our brothers.
In the end, being 'udhar' will only help us, our selves, in the long run. I say let us give DUAL CITIZENSHIP also.

If one of the people who have left the country for a long time remembers their country where they lives when they were young and wants to bring back the money they made in the foreign country and settle in Nepal why should we limit their freedom.

Do onto others, what you want others to do onto you. If you could, do you not want to travel the world and then come back home?
