I'm surprised to see Singapore behind some other countries. It's the main official language. When I visited Singapore, every person and group we overheard spoke english by default and with the same level of proficiency as american or british people (no accent). Also, everything is labeled mainly in english and only optionally in one of the other 3 official languages.
