In short: By the time a person is 18, they must effectively be able to communicate and understand conversationally in 2 languages and casually use them in daily life..., if not become completely fluent...
Other than that, any language goes (whether it is a locally-known one, or a popular one worldwide),
The only thing I hope to gain from this, is to rid the world of /Monolingual Betas/
Seriously though, has this been a policy before? Because I haven't heard of such one...
I think this can especially be used for citizenship...
Edit: I don't necessarily have any other presupposed requirements besides bilingualism, though we may have certain notions of such in this main goal
Edit II: In furthering this venture, I have realized that my liberalism may slightly poisoned my lens....
And for clarification...
Minimum dual language system:
Main national language + other language (likely another related language, but foreign ones are fine)
I agree, the fact that Spanish isn't mandatory from pre-school in the states is a fucking crime. Bilingualism is only a good thing, and there is so much cultural experience you miss out on by not speaking Spanish while living the Americas.
Maybe it's not learned great by everyone, but only by learning a bit will people start to learn how many more opportunities there are when you know two languages, and the drive to know more and more will come.
Agreed, though whatever language you may want to learn may depend on your mileage (eg. region, preferences etc.)
