This is very similar to a suggestion I’ve bantered about with friends over the last year, except that I put in a lower limit (I was thinking $250K). Regardless of the details and mechanics, I think it’s a very good idea to make it easier to get wealthy foreigners US visas, and to tie this in some way to real estate purchases. We already have a program with two separate investment levels for foreigners who want to start a business in the US. This is really just an extension of the same idea.
