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.
They locked down on this in the last few years, but I had friends come in through the EB-1. One didn't even get picked in the H-1B lottery and so had to work in India and that gave him the foreign manager experience. This is ~2018.
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".
It's not that simple. You need to have been a manager outside of the US for 1 year, apply and get approved for L1C visa, enter the country on that and then once in the US apply under EB1C. All the time maintaining legal status.
