Right, it's obviously your assumption, but you stated the resulting shitshow as an obvious fact—"let's not kid ourselves".

I doubt H-1Bs would oppose taking that test. Many already took English proficiency exams by the time they apply for the visa.

I assume Americans in general would favor this extra requirement too.

And companies, if we decide we care about what they want, really have no reason to oppose the test. There's a large enough number of applicants that they can easily pick from the ones that do speak English fluently.

So to conclude it would be a shitshow because of the politics is likely incorrect, certainly defeatist, and gives up on the actual thing we should strive for, which is to make the H-1B visa better.
