Rethink is right. Few of my friend who have returned to Nepal fit in the categories mentioned by Rethink. One of them had a very well established family business. I sensed that when he was in the US. His stay in the US looked to me more like a vacation. He changed schools every year, worked hard but spent all his money on parties while I was trying to save to pay-off my fees. He never cared about his studies and as soon as he graduated, he took the next flight back home and now works for his dad. Travels around, visits India, Thailand very often. Plays tennis, goes swimming in five-start hotels and then goes back to taking orders from his dad.
The other one, was more serious. Studies hard and worked hard. But decided to return to Nepal even before graduating. Got married to one of the politicians daughter. I didn't know that his dad was also a businessman back home. Now he has business mixed with politic power, so he is very successful at what he is doing.
When I visit them, they look at me like I am a loser working my ass off in the US while they are making as much money or even more working and enjoying their life in Nepal. But I don't care because I don't work for my dad.
