Remember H1B is a lottery. So yes, some of them will have the qualifications to get hired at places like FAANG. But many (most?) are pretty mediocre. There's also an extra allocation for people who get "advanced degrees" from a U.S. university. That's also a lottery, so most of the spots go to graduates of diploma-mill Master's programs. These programs are very lucrative for third-tier schools.
