in which he shows detailed figures for NET immigration flows into and out of the United States in comparison to countries like China and India?
Funny, I was just coming to the comments page to say exactly this. The linked post is conspicuous for its lack of words like "study" or "statistics." Talking to a couple of random people does not qualify a trend that stretches to millions of people.
It's pretty obvious that the U.S. immigration system is fucked up and should be much improved. But you can't jump from that to the conclusion that so many immigrants are going home as to affect Silicon Valley.
That's the thing, it doesn't have to affect a lot of people to be a big problem. Founders are pretty valuable, keeping even a small number of them out with artificial barriers is bad thing, since the alternative (letting them in) does not seem that daunting (unless you fear foreign founders for some reason).
