I don't believe these returning ppls intent. America is going through worse, and oppurtinities rt. after graduation or even after a couple of yrs of experience is in its worse for many. So lack of better here is encouraging you pps to go back, I bet noone planned to return nepal to help nepalis after graduation, when you first came here.
I now just want to hear a bunch of above returning planning ppl saying after a couple of year that they are doing great after returning there.

I see that you pps are serving your country even staying abroad. Obviously economy is worsening everywhere and its good to take a little break going back home. PPL going abroad and making strides of success have encouraged many students over nepal work hard with a sense of competition so as to meeet the achievement of their rival friends abroad.
If u go back with truthful heart, it will be great otherwise it will discourage many there.
