Well H1-b is for temporary foreign workers, so the restrictions would be on the companies hiring foreign workers rather than the immigrants themselves. Personally I think H1-b visas for lower end workers are just an excuse for companies who want to treat their workers poorly by offering lower wages and benefits than they would get with American workers. And of course that contributes to unemployment among low income Americans who would otherwise have these jobs. By all means we can have a mechanism that is more indifferent to money when we look at other categories of immigration.
