If they don’t immigrate (i.e. aren’t in anglophone countries), they might still take the test for domestic purposes like proving their ability to deal with tourists or other international customers to their employers. But the test takers are definitely self-selecting, some rural greatgrandmother who barely learnt to read her native language isn’t taking that test.
