O1 isn’t that hard with a good immigration lawyer. It’s about checking boxes, not extraordinary talent.
Pretty sure you also get a rubber stamp if what you’re doing is AI/ML related.
Sorry but the definition of extraordinary qualification is very capricious to make the claim about it being "hard" a bit meaningless. There are a lot of factors, but it isn't necessarily hard to obtain.
To me it's extraordinary because it's above what I'd consider ordinary. Let's say most people have Bachelor's and can't (or won't) start their own business. If you have someone with a Master's and also a startup owner they are extraordinary by that definition.
The USCIS has a much more concrete definition with different parameters. Is it an ideal one? No. But I guess any new improved definition still won't be universally accepted, especially by other talented people.
