US tech leaders sound alarm over Trump immigration order

Trump's order temporarily bars citizens of seven majority-Muslim countries from entering the United States even if they hold valid visas or permanent residence permits, a move that caught many companies off-guard.

Netflix Inc Chief Executive Reed Hastings called it "a sad week" and added: "It is time to link arms together to protect American values of freedom and opportunity."

Apple Inc CEO Tim Cook sent a letter to employees saying Trump's order was "not a policy we support" and promised to help affected employees.

"We have reached out to the White House to explain the negative effect on our coworkers and our company," Cook added.

Elon Musk, the South African-born founder of Tesla and SpaceX who met recently with Trump, said on Twitter: "The blanket entry ban on citizens from certain primarily Muslim countries is not the best way to address the country’s challenges."

Airbnb co-founder and CEO Brian Chesky said: "Not allowing countries or refugees into America is not right and we must stand with those who are affected."

Airbnb will provide free housing to anyone not allowed into the United States, Chesky said.

Aaron Levie, the outspoken founder and CEO of online storage company Box Inc, said: "The executive order on immigration is immoral and antithetical to our values."

Friday's order could be a major headache for tech companies, potentially leaving employees stranded overseas and unable to return to the United States.

Alphabet Inc's Google urgently called back employees from overseas and told ones who might be affected by the ban not to leave the United States.

CEO Sundar Pichai said in an email to staff that more than 100 Google employees were affected by the order, according to a Google executive.

One Google employee of Iranian nationality with legal U.S. residency made it back to the United States just hours before the order took effect, the executive said.

"We're concerned about the impact of this order and any proposals that could impose restrictions on Googlers and their families, or that could create barriers to bringing great talent to the U.S.," Google said in a statement.

Microsoft Corp President and Chief Legal Officer Brad Smith said in a company-wide email posted on LinkedIn that 76 company employees were citizens of the seven countries in question and held U.S. work visas, and thus were directly affected by the order.

He said the company had not determined how many people with green cards, or permanent residence status, might be affected.

"As a company, Microsoft believes in a strong and balanced high-skilled immigration system," Smith said in the post. "We believe in the importance of protecting legitimate and law-abiding refugees whose very lives may be at stake in immigration proceedings."

Uber Technologies Inc CEO Travis Kalanick, who has faced criticism from some employees for participating in President Trump's business advisory council, said in a statement that the company would compensate drivers from the seven countries who might not be able to return to the United States for three months or more. He said the company knew of about a dozen affected employees.

"This ban will impact many innocent people - an issue that I will raise this coming Friday when I go to Washington for President Trump’s first business advisory group meeting," Kalanick said.
