There is definitely commercial/political/etc. benefit to the US if it has businesspeople from multiple countries, but there's as much diversity of business relationships and value between, say, a Beijing entrepreneur and a Shenzhen entrepreneur as between a Czech and a Slovak. A point based system could factor in a lot of things. There's also value in having the world's 20 top OCaml developers (15 of them are likely French) as well as the world's top 20 server-side ARM multicore guys (who are also likely French) vs. 40 top OCaml people (where there may be more French people.) The easiest way to address all of this is for financial value to be the main factor. You can bring in people if they pay something like 200% of the US average wage as a surtax above their regular income tax and other costs. There could be explicit charities to subsidize things other than direct wage income value -- maybe an arts charity covers the $100k/yr to bring in a brilliant artist who is paid an additional $50k/yr in income and pays 5k/yr tax on that.
