H1B isn't the O1 visa. It's just very generic and broad. It could be brilliant engineers but more often than not it's just shitty consulting (Cognizant, Infosys) spaghetti coders. Look who takes the lions share of H1Bs and you'll see who we're bringing in. These are not experts lol, they're just cheaper and more desperate.

Which is exactly why the largest block of H1B visas goes to the shittiest companies.
