Almost 100 technology companies including Apple, Facebook, Google and Microsoft think have filed a motion in court opposing the recently imposed travel ban from the Trump administration.
The companies, 97 in total, filed their support in an amicus curiae submitted as part of the State of Washington's case against Donald Trump in the Court of Appeal, which was filed after the initial law was overturned by a federal judge on Friday.
As well as outlining many of the legal argument against the order, the companies also warn that it poses major risks to their position as the world's leading companies.
"The Order represents a significant departure from the principles of fairness and predictability that have governed the immigration system of the United States for more than fifty years - and the Order inflicts significant harm on American business, innovation, and growth as a result," it states.
"The Order makes it more difficult and expensive for U.S. companies to recruit, hire, and retain some of the world's best employees. It disrupts ongoing business operations. And it threatens companies' ability to attract talent, business, and investment to the United States."They also cite the importance immigrants have had in the history of America, particularly around innovations that have helped change the world and establish hugely successful businesses.
"Immigrants make many of the Nation's greatest discoveries, and create some of the country's most innovative and iconic companies. Immigrants are among our leading entrepreneurs, politicians, artists, and philanthropists," it said.
"The experience and energy of people who come to our country to seek a better life for themselves and their children—to pursue the "American Dream"—are woven throughout the social, political, and economic fabric of the Nation."
President Trump has already been vocal in his anger that the order has been halted, and vowed to ensure it will be restored.
The incident underlines the growing discord between tech companies and the government, with Uber CEO Travis Kalanick announcing last week he would step down from Trump's economic advisory board.
