Well that's just flat out not true (the percentage is high, but not 90%), and you've completely ignored the meat of the criticism above.

You're right, turns out it is about 70% https://www.mercurynews.com/2018/01/17/h-1b-foreign-citizens...

What exactly is the meat of the criticism above?

>most of the foreign born workers in silicon valley are people who immigrated to the US as children

Where did you get this stat? You're calling others liars while posting questionable stats yourself.

A lot of foreign born workers are not H1B because they got their green cards or citizenship. I'd safely say a majority of them were H1Bs till recently. Till 2008, getting a green card for any country was not a problem. It has gotten a lot worse since then.

Born outside the U.S. ⊇ H1B migrant workers. The majority of those born outside the U.S. are immigrants.

I have and even more, I know people who work in silicon valley. Have you been there?

Ignoring the fact that "90% of tech workers there were born outside the USA" is absolutely false, what does that have to do with H-1B visas?

It could be true that 90% of tech workers were born outside the USA and none of them could be H-1B visa holders. There are plenty of american tech workers who immigrated to the US as a child and became american citizens. Like sergei brin or jerry yang. They may be born outside the US, but none of them are H-1B visa holders. They were all american citizens.

The fact that you are intentionally lying and being sneaky with stats is very worrisome.
