It's definitely more difficult but well within reach of founders (particularly founders with funding and organic press coverage) and talented professionals. That is, until very recently. It's too early to say whether this is a trend or an aberration but the past few weeks we've seen USCIS apply a different standard, one similar to the EB1A standard. If this is a trend, then I suspect that the RFE and denial rates for O-1s will skyrocket.
