The reality is that the H1B program is being used not to bring in individuals with 130+ IQ, but essentially anyone with a bachelor's degree, which can be easily obtained from diploma mills. In some third-world countries, you can even buy your degree outright.
For the top 0.1%, there are O1 visas, as well as EB1 and EB2-NIW visas — the latter two don't even require an employer and can be self-sponsored. Plus, they grant you a green card, unlike the H1B, which ties you to an employer.
However, to qualify for these visas, you need to demonstrate that you're genuinely valuable to the U.S. They are designed for top-tier entrepreneurs, engineers, scientists, and artists with a verifiable track record. These visas can also be gamed, but it's much harder than with the H1B program.
