This paper provides the first study combining firm-level panel data on H-1B outcomes with a general equilibrium model of firm dynamics to quantify these effects. Using the random allocation of H-1B visas in the FY 2014 and FY 2015 lotteries as quasi-random variation, the authors find that lower H-1B visa win rates significantly reduce the survival of young firms (aged 0–5) in technology-intensive sectors, while the impact for older firms is not statistically significant. A general equilibrium model with endogenous firm entry and exit, skilled foreign labor, and H-1B-style policy frictions matches the age distribution of high-tech firms and shows that eliminating major immigration policy frictions would increase average productivity in the high-tech sector primarily by enabling more young firms to enter and survive, which in turn drives the exit of older, less productive firms.&lt;/p&gt;</description></item></channel></rss>
