Apple is one of around 300 businesses signing an open letter to President Trump urging him not to deport those young adults nick-named ‘the Dreamers’ – first brought to the U.S. illegally as children, but now registered, working and paying taxes.

The Obama administration introduced a program called Deferred Action for Childhood Arrivals, or DACA, which gave them permission to remain living & working in the USA so long as they obtained and renewed work permits. Trump plans to eliminate this program later today …

Re/code reports that Trump plans to immediately cease issuing and renewing all work permits.

The letter, signed by Tim Cook, points out that DACA participants are highly productive members of society.

It argues that deporting them would harm the U.S. economy.

It says that Dreamers are vital to the future of their companies and to the country, and calls on Trump to preserve the program and Congress to pass a bipartisan act to protect those affected.

The nickname calls to mind the Apple credo, whose opening includes the goal ‘to help dreamers become doers.’ The letter was also signed by Laurene Powell Jobs.
