Newly arrived,
I take it that the $$15K you are referring to is your nett salary per month?
Not inclusive of housing, schooling, transport etc.,???
If you're bored at home doing the usual routine and would like to experience a different culture, Singapore is a good place to be. Just make sure you have calculated all areas of expense before giving in your notice!
Other than that, overseas experience on your CV ought to be beneficial....(so my hubby says!)
