As one way to unload the glut of housing inventory languishing on the market, two senators want to introduce a bill today that gives foreigners who buy a home in the U.S. a residence visa.

Foreigners would have to invest at least $500,000 in residential real estate (buyers can invest in more than one home as long as one is for $250,000 and the total is at least $500,000) and supporters of the proposal say it will help compensate for the lack of U.S. buyers.
