I know this is a politically sensitive topic, so full disclaimer: I live outside the US but I work (and worked) for a company whose headquarters are in the US.

I know this is a politically sensitive topic, so full disclaimer: I live outside the US but I work (and worked) for a company whose headquarters are in the US. So I know people in different visa situations. I see this type of measure as something that has a xenophobic base. The economic problem can be approached by applying sanctions to companies that use visas for cheap labor, not to the immigrants. But that type of action will be seen from a part of the US society as anti-capitalist because it attacks companies and businesses. So a big chunk of the society prefers the xenophobic idea of blaming the immigrants because they "steal" the job positions, but very little is said about the companies that abuse from cheap labor to be competitive.
