No, I sure don't! I still love the country in my heart, but not in my head. VN is nice for visit, but it not nice to live there; unless you have a lot of monies and good connection up there.
I went back many times, from begin I though about going back to stay, than I see the disapointment of the people around me when they think I about run out of money.
Job is not easy to find. An engineer make about $300 a month in SG, it not goes very far since everything cost a lot more nowday. And think about sickness, hospital...anywhere you go, you have to bribe...If you are young, you might make it. Good luck!
