Most lawyers I've spoken to disagree with this. The O-1 and EB-1 have similar criteria as written, but the EB-1 is adjudicated to a much higher standard than the O-1.
But I agree, I didn't mean it has the same true requirements, just that it is the "corresponding" category. So yes, not "equivalent", "corresponding".
Eb1a is the tough category they are talking about.
