I never said any of this. allowing non-native english speakers to communicate with the government in their native languages facilitates a positive economic impact, efficient use of resources, ensures they're aware of their responsibilities and rights and they can also report emergencies.
In the example you put forth, the language skills isn't the problem, it's their values.
"allowing non-native english speakers to communicate with the government in their native languages"
does not have any economic impact either way
it is very inefficient to have government forms in different languages, the idea that it increases efficiency is so absurd, it actually creates a new layer of bureaucracy.
It also creates a set of jobs in both the private and public sector in which it becomes legal to discriminate against people that only speak English. Bilingual requirements have been used extensively to discriminate against black job seekers
Their responsibility is to learn English, using English they can learn how all their rights come from what black Americans fought for and how to respond to emergencies
Overall you are trying to solve a problem that doesn't exist, the us and nyc ran totally fine with English government forms while absorbing millions of immigrants
