H-1B Immigration Linked to Increased Incomes for U.S. Natives and Immigrants

H-1B Impact on Incomes

Research on the long-run effects of H-1B immigration on the U.S. economy indicates that exposure to H-1B workers led to increased incomes for native-born Americans and immigrants already residing in the country. These income gains were primarily observed in non-STEM occupations.

Propagation Through Supply Chains

The study found that these income gains extended forward through supply chains to downstream industries. However, no similar effect was observed propagating backward to upstream industries. This pattern suggests that the H-1B immigration acted as a productivity shock within the affected industries.

Productivity vs. Innovation

The findings suggest that the productivity gains stem from improved task execution rather than from patentable inventions. The study reported no direct effect on patenting activity, differentiating the nature of the economic impact.

Methodology

The research utilized a cross-industry design and focused on the 1999–2003 expansion of the H-1B visa cap for identification purposes. This approach allowed for an analysis of the effects on U.S. industries employing H-1B workers and their trading partners.
