Dual citizenship is not gonna happen is Nepal, it’s a complex matter. The only way is to renounce your citizenship from your resident country.

If you have lot of ancestral property , getting a US citizenship might be a bad idea. You think those social security benefits that you’re salivating on is more than the property in Nepal ? I don’t think so... and even social security is not guaranteed !

Make a smart decision now rather than regretting later.
