If you spend within your means, surely you can save and have your family here. I know of some Asian expats who earns less that 10K and yet living a decent life.

Honestly, this is above average offer and your expenses will entirely depend on the kind of lifestyle you want to live or.... you want to project.

For example, I saw Asian children here in Doha who have ipads and top of the line phones even at a very young age.

If this is the kind of life you want, surely you still can live but you can't have savings.

Cheers
