Jerry Yang and Sergei Brin immigrated to the US when they were children and they became citizens before they co-founded yahoo or google. Also, you leave out the fact that two of the founders of Google and Yahoo ( david filo and larry page ) were native born americans.
As for Elon Musk, his grandfather was american and he became an american citizen in 2002 before he founded tesla.
In other words, Yahoo, Google and Tesla were founded by american citizens.
You are intentionally conflating immigration with h-1b visas and lying about the founding of yahoo, google and tesla to push an agenda. That's disappointing.
