Any argument that looks at job creation in isolation is next to worthless. Such an argument leads to conclusions like "we need visa reforms to ensure that only really skilled people get through". Skill based criteria are almost always absurd. I'm pretty sure that in a country as large as the United states, there's a good chance that you'd find enough number of skilled people in all domains. So the obvious factor which drives companies to recruit foreign workers is the cost of labour. That begs the question: "why are natives not okay to work at the salary levels of immigrant workers?". There could be two reasons: either their liabilities are greater, or it is that prevailing culture that discourages US natives to work at lower salaries". From that perspective, the natural way forward for the US government should be try and reduce the liabilities of the natives. Why cant they make education cheaper and more accessible? What can they do to reduce the price of housing? How do you reduce the cost of transportation?

IMHO blaming immigrants/the companies that hire them is not productive. Businesses try to maximize their profits; that's given. They aren't hiring immigrants through benevolence towards immigrants or aversion towards natives. The US should fix their social problems before blaming the immigrants/corporations.
