He/she should have option of coming back, if things really didn't work out. I have seen lot of got adjusted and also a lot who came back again after trying for around year. So it might work or it might not, but hey it's worth trying, if you get fascinated by love for your country or family back there.

Like others I also like to know about personal situation back home, like financial situation, business or job situation, wealth, age & things like that to correlate my self. I am getting very close to make such decision, and like to get some reference from people , who have make that call. I am here for last 10 yrs, and I think I should make some decision in next 2-3 yrs.
