In response to the announcement that the Trump administration will be shutting down the Obama-era “Dreamers” immigration program, Silicon Valley companies are speaking out... Hundreds of tech leaders co-signed a letter [before the decision] titled “Leaders of American Industry on DACA" [stating], "... Unless we act now to preserve the DACA program, all 780,000 hardworking young people will lose their ability to work legally in this country, and every one of them will be at immediate risk of deportation. Our economy would lose $460.3 billion from the national GDP and $24.6 billion in Social Security and Medicare tax contributions. 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."... [Facebook CEO] Mark Zuckerberg [wrote], "We need a government that protects Dreamers. Today I join business leaders across the country in calling on our President to keep the DACA program in place and protect Dreamers from fear of deportation. We're also calling on Congress to finally pass the Dream Act or another permanent, legislative solution that Dreamers deserve."... [Microsoft] CEO Satya Nadella posted, "For Microsoft, the first step is clear. The administration has given Congress six months to replace DACA with new legislation. We believe this means that Congress now needs to reprioritize the fall legislative calendar and move quickly with new legislation to protect these 800,000 Dreamers. This means that Congress should adopt legislation on DACA before it tries to adopt a tax reform bill. This is the only way, given the number of legislative days Congress has scheduled over the next six months, we realistically can expect Congress to complete DACA legislation in time...[Microsoft] will work as needed with other companies and the broader business community to vigorously defend the legal rights of all Dreamers.”
