Agree the rate of top US companies hiring foreign tech workers has massively increased in the past decade. But no, its not at the expense of US citizen employees. I work at a FAANG (5+ years at one, 10_+ years in other big companies). We are actively hiring great talent. The majority is white males, because...statistics. HR recruiters try to serve us a diverse pool of resumes/candidates to screen but its actually hard to find enough to fill all the roles we're hiring for (in cloud computing). Results in teams of mainly white males. Hopefully your 'anecdotal experiences shared online' are just a subset of the few that don't make it past an initial screen vs. the majority that do.
