The steven hawking outliers can apply under the O-1 visa type schemes, which he would definitely pass. A points scheme doesn't have to be the only scheme.

And you think of the millions of people wanting to get in here they're all world-renowned physicists or spiritual leaders? We would long run out of money supporting the hordes of cancer-stricken dirt farmers clamoring to get in here before the next Stephen Hawking shows up.

You get an exemption from the rules if you are a Nobel Peace prize winner or were ever the Lucasian Professor of Mathematics at Cambridge.
