The US naturalization laws require one to prove English proficiency and to pass a US history test before he/she can get citizenship. How might one move here legally without being proficient in English (besides reading the test gouge) as you suggest?

I am pro immigration, fwiw. I'm just tying to figure out how people can legally not learn English and live in America. People can speak whatever language they want here. That is a right/freedom enjoyed by all of us. But there is still a requirement to demonstrate proficiency in the English language.
