More than 350 executives of the major U.S. companies signed a letter on Thursday to President Trump. The letter implores Trump to keep legal protections for undocumented immigrants to the U.S. that are brought as children.

The letter is penned by, an immigration reform group. This organization has Mark Zuckerburg’s backing. Among the executives that signed the letter are Apple’s Tim Cook, Google’s Sundar Pichai, Microsoft CEO Satya Nadella, Amazon CEO Jeff Bezos, Hewlett-Packard CEO Meg Whitman, and others.

The letter is addressed to not just Donald Trump, but also Senate Minority Leader Charles E. Schumer, Senate Majority Leader Mitch McConnell, House Minority Leader Nancy Pelosi, and House Speaker Paul Ryan. The aim of the letter is to seek continuation of the DACA (Deferred Action for Childhood Arrivals) program. This program provides safety against deportation to children that are illegally brought in America.

In the context, Trump is expected to announce a major change in immigration policy this Friday. This major change would significantly remove DACA protections. According to a report, about 800,000 people covered by DACA may not receive work permit renewal after their documents expire. Also, undocumented young adults will be open to deportation.

According to the findings of, the policy reversal would take away about $460.3 billion of national GDP and about $24.6 billion of Medicare and Social Security tax contributions.

As the letter reads, “Dreamers are vital to the future of our companies and our economy. With them, we grow and create jobs. They are part of why we will continue to have a global competitive advantage.”

“We call on President Trump to preserve the DACA program. We call on Congress to pass the bipartisan DREAM Act or legislation that provides these young people raised in our country the permanent solution they deserve.”, the letter concludes.
