Are you single or married? If you single and go SG the chance you remain single till you retired is high. There is no right or wrong to go SG. Going SG you can earn more due to exchange rate, the culture is much civilise compare to Msia, convenient public transport, highly efficient in almost everywhere, no racism, stable politic, much safety.

But there are drawbacks too.
1. Unable to come back to Msia to work. You won't satisfied with Msia salary anymore even if you being offer as manager role and salary. There are many people said go SG to work 2 years but end up most if not all work till retire or retrenched in SG.

2. Less relax or leisure moment. The purpose going SG is to earn and save money. If you go too much shopping in weekend basically can't save much. To save money your weekday work and weekend home. 1 year maybe go travel overseas twice to reward yourself.

3. Find partner. Even local SG finding it hard to get partner, foreigner will get harder. Imagine if you can't find partner in workplace the chances you meet partner outside even harder since weekend mostly at home. All my friends went SG remain single until now and some of them nearly 15 years there.

4. Many said work in SG and retired in Msia. Good point but there are problem people do not foresee. If you live in a country which highly safe, very clean, efficient in everywhere, great public transport etc many years, they may find it hard to come back and live in Msia.

I got an opportunity to go SG when I was young but I decided to stay. I am happy I can stay with family, weekend chill out with friends, holidays go road trip with friends and family etc. In SG I definetely can earn more there but I am happy at Msia coz I formed own family and enjoy my life in Msia.
