Right-wingers turn on Elon Musk over his latest immigration stance

Billionaire Elon Musk is coming under fire from some right-wingers online over comments he made in support of H-1B visas, non-immigrant visas that allow employers to hire highly skilled foreign workers.

This visa program was established in 1991. Congress sets annual limits on the number of visas that will be issued. It's currently set at 65,000.

Companies including Amazon, Google, Microsoft, and IBM are among those that employ thousands of foreign workers with H-1B visas.
