For what it's worth, the program doesn't provide a substantial advantage over existing visas, due to the requirement of $250k+ in funding.

Immigration lawyers I've discussed this with have noted that if someone has $250k+ in funding, they are generally able to get an O-1 visa, anyway.

So while this process would likely be easier, it won't help many people who couldn't get a visa via another path.

If the requirement was changed to benefit people pre-funding and give them 2-4 years to show promise, then this would be an extremely beneficial rule.
