If locals don't speak it what's the point? They'll reverse to English as soon as they are here. It's not like they're going to speak in within their families.

If locals don't speak it what's the point? They'll reverse to English as soon as they are here. It's not like they're going to speak in within their families. They'll learn just enough to pass the entry test and that'll be the end of it. It's very hard to learn a language, it's even harder to force people to learn it if they don't want to. Integrating yourself into your country of adoption is very hard, forcing immigrants to learn a minority language would make it even harder. Can you imagine if, say, France asked Syrians refugees to learn Breton instead of French? That would be insane.
