Increase the mimum pay for O visa holders. If they’re that extraordinary, then they deserve $50K a month.
I doubt any O visa holders are getting less than $50k/year. First of all, it wouldn’t make sense for the company to spend $20k to get that kind of worker. Second, people who have those kind of accomplishments can make a lot. Even college professors with O Visas makes that. There are less than 25k O Visa holders in the entire country.
