United States presidential aspirant Donald Trump published his first policy paper, in which he publicly criticized some prominent politicians and businessmen, including Facebook founder Mark Zuckerberg.

In his policy paper, Trump declared his opposition to the H-1B visa program arguing that that the United States, especially the Tech moguls in Silicon Valley, should employ more women, Hispanics, and Black Americans before hiring foreigners. Trump noted that only half of American college graduates with science, technology, engineering, and math degrees find degrees in their field.

According to Workpermit.com, "The US H-1B visa is a non-immigrant visa that allows US companies to employ foreign workers in specialty occupations that require theoretical or technical expertise in specialized fields such as in architecture, engineering, mathematics, science, and medicine. Under the visa a US company can employ a foreign worker for up to six years. "

The Republican candidate said that a real immigration reform puts the needs of working people first, not wealthy donors. The U.S. is the only country in the world whose immigration system puts the needs of other nations ahead of its own.

According to Trump, politicians and businessmen, including Zuckerberg, only want cheap labor. The Real Estate giant also singled out Marco Rubio, calling him Zuckerberg's personal senator. Zuckerberg and Rubio have been allies in supporting foreign employment in the U.S.

Zuckerberg leads a political action group called Fwd.us. The cause wants more H1-B visas granted because tech companies cannot find all their labor needs in the U.S., CNET reported.

Rubio passed a bill to triple H-1B program beneficiaries, which according to Trump, would decimate women and minorities.

Zuckerberg has not yet given his side on Trump's latest release. In the past, however, Zuckerberg had declared that foreign workers collaborate more than compete with Americans. Each group has its own strength and when they work together, they synergize.

Meanwhile, Silicon Valley has a long way to go when it comes to workforce diversity. Published reports on the 2014 workforce of Facebook, Twitter, and Google, show their employees are mostly white and male.

Nonetheless, there were also companies who have promoted workplace diversity. During the recent White House Demo Day, President Barack Obama applauded the efforts of Pinterest and Intel to empower women in tech.

Pinterest encourages creative collaboration among its employees from different backgrounds. As seen in its hiring video, Pinterest expects women to be as good as their male counterparts.
