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 can't interpret what you're saying without a translator except for 4-6 words, but I recognize enough to conclude that it is very normal for someone saying that to have the idea/worldview/assumptions/values expressed in the OP.
But I mean that in a positive light.
Yeah, my Tagalog's been a bit rusty...
If you speak or write Tagalog then you are familiar with being in a country that has multiple regional languages, so being multilingual is quite normal for you.
The thing is I'm a migrant to UAE, so I haven't been as exposed as much to it... let alone the other languages.... but it's familiar to me via my parents...
