Immigrants and children of immigrants are over-represented among the US team members. Still survivorship bias. Immigrants from China and India are not selected randomly from the population, they're selected by their means and determination to emigrate. Furthermore, if you include the fact that the US caps the number of visas granted on a per-country-of-origin basis and the fact that China and India have the 2 largest populations in the world, the people who successfully obtain visas from these countries are the survivors of the most stringent selection process.
