The O-1B category is broad because it's mostly entertainment based so there's more squishy room two of the requirements match a Top OF model though.

> Evidence of a record of major commercial or critically acclaimed successes in the performing arts, as shown by box office receipts or record, cassette, compact disk, or video sales

> Evidence of having commanded a high salary or other significantly high remuneration for services in relation to others

A high earning OF model ticks both of those boxes pretty easily. We don't want to put dollar amounts on it to only attract movie stars because other professions don't pay as well would be blocked out and an explicit filter on (heh) explicit O1 visas would be a content based restriction that would (or at least imo should) be a 1A infringement.

[0] IMO a 1A restriction to who can come to the country is defacto a restriction on speech in the country.
