This is a fantastic article.
I have a Green Card, so have read and know more about US Immigration policy than anyone should ever wish to, and I had no idea that the EB-1 was this attainable, and I've actually sat down and read USCIS's EB-1 page and parts of the policy manual.
I genuinely believe there's going to be someone out there that reads this having previously dismissed the EB-1 (just like I myself did) and gives it a shot. The visa is definitely set up to seem out-of-reach for non-celebrities/field specific rock stars.
Another example of this working, Melania Trump (then Melania Knauss) earned an EB-1 while being a mid-tier model with no huge acclaim. Although she was assisted by her agency and similar, so they may have a marketing budget to get her name/acclaim out there.
