"The results of our analysis are clear. Cities whose employers faced large numbers of denials in the H-1B visa lotteries experienced considerably less job creation and wage growth for American-born computer workers in the two years that followed. Denying H-1B visas didn’t help the economies of America’s cities or their U.S.-born workers. Instead, it cost their tech sectors hundreds of thousands of jobs and billions in missed wages." - Giovanni Peri, Kevin Shih, Chad Sparber, Angie Marek Zeitlin, June 2014.
