Brightest in the world definitely isn’t what H1B recruits on. It recruits on who is the most desperate to do hundreds of leetcode problems in order to stay in the country.

Go figure, people who want to stay in the country will jump through some ridiculous hoops and we’re all worse for it.

I have never found a reason to believe any folks on H1B are smarter than their non-H1B peers. By any stat, never seen it.
