It's not that Nepal is a violent dictatorship like North Korea.  Neither is it a socially oppressive country like some of those sub-Saharan nations where they enforce brutalities such as female circumcision.  Nor is it a Maoist nation suffering from their so called "cultural revolution", at least not yet.  

So for what factor does the US immigration see as compelling reason for granting asylum?   

It is purely academic curiosity and I am not trying to be judgmental here.  I perfectly understand that that if there is a legal path, then people have all the rights to pursue their desires.
