97 companies, including tech giants such as Google, Apple, and Facebook, and Twitter, have filed an amicus brief in a Washington state court.

Amicus brief is a legal document filed in appellate court cases by non-litigants who have a strong interest in the subject matter. The briefs are meant to advise the court of relevant information or arguments that the court might wish to consider.

What the brief says, among other things, is this - "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," the brief reads, indicating a philosophical objection from the signees. But they also present an economic argument, saying that the order also "inflicts significant harm on American business, innovation, and growth," disrupting current operations, and making it "more difficult and expensive for US companies to recruit, hire, and retain some of the world's best employees."

In addition to the aforementioned companies, also Netflix, Uber, Spotify, Microsoft, eBay, Quora, Reddit, Airbnb, Linkedin, Mozilla, Pinterest, Wikimedia, Kickstarter are on the list. While Amazon is not on the list, they are also on the same side.
