"All DACA recipients grew up in America, registered with our government, submitted to extensive background checks, and are diligently giving back to our communities and paying income taxes," said the letter. "More than 97 percent are in school or in the workforce, 5 percent started their own business, 65 percent have purchased a vehicle, and 16 percent have purchased their first home. At least 72 percent of the top 25 Fortune 500 companies count DACA recipients among their employees."

Among those who have signed include tech bigwigs like Amazon CEO Jeff Bezos, Facebook CEO Mark Zuckerberg, Twitter CEO Jack Dorsey, Apple CEO Tim Cook, Google CEO Sundar Pichai and Warren Buffett. CEOs, founders and representatives from Airbnb, Dropbox, eBay, Fitbit, Foursquare, GoFundMe, LinkedIn, Lyft, Netflix, Netgear, Pandora, Tesla, Tumblr and Uber have also signed.

Highlighting just how much DACA recipients contribute to the US economy, the letter stated, "Our economy would lose $460.3 billion from the national GDP and $24.6 billion in Social Security and Medicare tax contributions."

Trump was vocally against DACA during his campaign and is largely expected to cancel the program by September 5th -- a deadline Republican lawmakers set for the president to make a decision. White House Press Secretary Sarah Huckabee Sanders said the president hasn't yet made a final decision, but will announce one on the 5th.
