My father, almost 60 is trying to apply for US citizenship. I htink after getting US citizenship he has to give up his Nepalese citizenship. In that situation, can he maintain his current properties like land/house or buy new properties in Nepal?
Also, I am his married son still in nonimmigration status. Once he become US citizen and If he is ready to sponsor for green card for us, does it take really long time like 2-3 or plus years for petition to get approved?
Thank you.
