On the business side, two broad changes come to mind: I would make it easier for entrepreneurs/founders to start businesses and also make it easier for the super skilled/talented (in both the arts and business) to get visas without needing employer sponsorship. I also would like to see the U.S. government come up with a list every few years of occupations (both skilled and semi/unskilled) that are considered critical or in short supply in the U.S. and make it easier for foreign nationals to get visas or even green cards for those occupations.
