Coping with H-1B Shortages: Firm Performance and Mitigation Strategies.

The H-1B visa program allows companies to hire skilled foreign workers. Before 2014, the vast majority of these visas were allocated on a first-come-first-served basis. Since then, the program has been severely oversubscribed and all cap-subject visas have been allocated through lotteries. The authors merged Compustat data with administrative firm-level data on the universe of approved petitions for H-1B visas. Using difference-in-differences and matching estimators, this article finds that the switch in the visa allocation system negatively affected the growth of companies that used the H-1B program. Results indicate that these effects are quantitatively large and that their magnitudes grow over time. [ABSTRACT FROM AUTHOR]
