Im exploring my options. Singapore is home for me. If i can get a decent salary doing what I like to do (environmental management/science/planning) in Singapore, its likely that i'll come back. but I do agree with your point about the possibility of my degree having more worth overseas since environmental/natural sciences is a very small and niche sector in Singapore. The thing about working overseas is that Visa/PR is troublesome to get and there'll always likely be some form of prejudice to foreigners (im talking about western countries i.e. Australia) and I wanna do my part for singapore as well in a way.
