Mark Zuckerberg, Tim Cook, and Jeff Bezos are among more than 100 prominent business leaders urging Congress to pass legislation protecting young immigrants.

In a letter dated January 10, the executives asked lawmakers to extend the Deferred Action for Childhood Arrivals (DACA) program by January 19, a month and half before it is set to expire. The Trump administration announced in September that it would end the Obama-era program, which prevents the deportation of undocumented people who arrived in the U.S. as children, also known as Dreamers. 

"We write to urge Congress to act immediately and pass a permanent bipartisan legislative solution to enable Dreamers who are currently living, working, and contributing to our communities to continue doing so," the executives wrote in the letter. "The imminent termination of the DACA program is creating an impending crisis for workforces across the country."

Google CEO Sundar Pichai, Salesforce CEO Marc Benioff, and Twitter CEO Jack Dorsey also signed the letter, which was published a day after a federal judge in San Francisco temporarily blocked the Trump administration's decision to end DACA.

DACA allows about 800,000 immigrants to stay and work in the country. To qualify, applicants must have entered the U.S. before the age of 16, lived in the country continuously since June 2007, and have committed no serious crimes. Silicon Valley executives were among the most vocal opponents of the White House's decision to end the program, often citing a CATO Institute study that found that ending DACA could cost the U.S. economy $215 billion.

A growing number of Democratic lawmakers also joined the fight and announced they will not support a new spending bill unless the fate of the Dreamers is secured. Republican leaders said they opposed adding immigration provisions to the bill ahead of the Jan. 19 deadline. Failure to reach an agreement would force a shutdown of the government.
