> A lot of US tech exists because of skilled foreign workers. I'm not sure what would be the tech industry without them.

Relevant historical footnotes: The Manhattan Project [0], where an international team of scientists and engineers built the world's first atomic bomb.

Operation Paperclip [1] where Nazi scientists and engineers were hired by the US government to work on the space program, amongst other things.

and of course, there's this Andrew Grove guy, [2] who convinced the tech industry to obsessively focus on KPIs, for better or worse.
