I believe above article portrays mostly the Chinese and Indian immigrants.  They are the ones who are returning back to the country of their origin in droves.  Why you ask?  Well, that is because their country got their ducks in order.  Those nations created a welcoming, attractive and lucrative environment for these highly skilled, highly educated, highly motivated workers to come home to. 

Sadly, this is not the case for Nepali immigrants.  If anything, it is the opposite, even more so, for us.
