Re: that last point, you're exactly right. See Nikki's piece (search: O-1) https://medium.com/@nikkidurkin99/my-startup-failed-and-this...
Unfortunately, that's a feature, not a bug. The anti-fraud people prefer it that way, and they have a lot of influence within DC to block these proposed changes.
Luckily, the O-1A, in contrast with the H-1B visa, is that it is an analog to a green card, the EB-1A, so if you are able to get an O-1A and wish to get the professional stability that a green card offers, you should be able to quickly progress from O-1A to EB-1A, which doesn't have the badly backlogged lines (especially for Indians or Chinese) of the EB-2 or EB-3 work-based, academic-qualifications green cards.
