Donald Trump has a new target for his criticism of the nation's immigration policies - Facebook founder Mark Zuckerberg.
Trump said he wants to require employers to pay H-1B workers much more money, which he said would discourage companies from hiring them and boost job prospects for Americans. He also wants to have tech jobs offered to unemployed Americans before they can be filled by workers with H-1B visas.
"This will improve the number of black, Hispanic and female workers in Silicon Valley who have been passed over in favor of the H-1B program. Mark Zuckerberg's personal Senator, Marco Rubio, has a bill to triple H-1Bs that would decimate women and minorities," Trump wrote in his immigration plan. Rubio is also seeking the Republican nomination for president.
Zuckerberg started a public interest group called Fwd.us to push for immigration and lobbying reform along with Microsoft founder Bill Gates and Yahoo CEO Marissa Mayer. Neither Facebook(FB, Tech30) nor Fwd.us had an immediate comment on Trump's criticism of Zuckerberg.
Trump says that there are plenty of graduates with degrees in science, technology, engineering and math, known as STEM, to fill tech jobs. That means that employers don't need H-1B visas to fill jobs, and are using them instead to keep wages low.
Employers are supposed to pay a typical wage to anyone hired under a H-1B visa. But in reality, employees on these visas are typically paid 20 to 45% less than U.S. workers who they are are often replacing, said Ron Hira, a Howard University public policy professor who has studied the visa's pay scale.
"I don't think you should eliminate the H1-B program. The problem is it's being abused and it's a source of very cheap labor," said Hira.
