As far as 4 goes, ratios are a better solution to the body shop problem. There’s no need to even limit the number of work visas granted so long as the companies that are able to hire foreigners also hire the requisite number of Americans in similar positions. There are a number of other advantages to this too. For one, it helps immigrants integrate better the more Americans they end up working with. The current system can result in silos where immigrants mostly work with other immigrants. And it helps Americans to work alongside skilled workers by giving them increased learning opportunities. It also works better for lower-paid skilled positions like nurses and scientists who don’t have to compete with higher-paid tech workers for visas. I’m okay with giving an unlimited number of visas (background checks required) to any company that employs at least 70% Americans in each salary band. At worst, it creates an incentive to hire unqualified Americans just to get access to foreign talent, which is still a win for this country.
