Will stopping immigration cause labor shortages?

Will halting immigration tighten labor markets? I'll pull recent research on where shortages would emerge.

Stopping or sharply reducing immigration would likely cause labor shortages in the short-to-medium term, but the size and duration of those shortages is debated and depends on sector, timeframe, and how the economy adjusts.

1. Why most economic research predicts shortages if immigration stops

Economic literature generally finds that more immigration increases the U.S. labor force, enhances productivity, and grows the economy, while deportations and restrictions are contractionary.

Demographics amplify this effect. Immigrants have historically accounted for more than half of total labor force expansion in the United States over the previous decade, and projections estimate that reduced immigration could shrink the labor force by significant amounts:

2. Sectors most vulnerable

Nearly one in five U.S. workers is an immigrant, but concentration is much higher in certain industries:

Proponents of this view argue immigrants often work in jobs that are complementary to native-born workers, supporting employment for those workers rather than taking away opportunities. For example, a native-born engineer, architect, plumber, or electrician would find fewer work opportunities if immigrant construction laborers were deported.

Recent labor market data from 2025 is cited as evidence: The unemployment rate for people born in the United States rose even as the number of immigrant workers fell sharply. Specifically, the unemployment rate for U.S.-born workers increased from 4.3 percent in January 2025 to 4.7 percent in January 2026 even as enforcement reduced the foreign-born workforce. Supporters of this interpretation argue that when businesses cannot find enough employees, they often scale back operations or delay expansion, leading to fewer job openings overall, and that immigrants also contribute as consumers and entrepreneurs, so shrinking their numbers reduces demand and business creation.

3. Counterarguments: Why some analysts say shortages would be limited or temporary

Not all economists predict widespread shortages:

Critics of the labor-shortage forecast argue:

From this perspective, stopping immigration would force employers to solve labor shortages by raising wages, recruiting underutilized domestic workers (including teenagers, older workers, or non-participants), investing in labor-saving technologies, and automating tasks. Historical examples are sometimes cited, such as the 1964 end of the Bracero program, where jobs previously filled by seasonal immigrant workers were either replaced by machines or eliminated entirely due to decreased domestic production rather than filled by native workers at higher wages.

4. How the answer depends on assumptions

In summary, the majority of recent economic studies and industry data suggest stopping immigration would exacerbate existing workforce shortages already affecting small businesses, increase costs, and reduce access to health care and other services, particularly in agriculture, construction, and health care. Other analysts contend the aggregate effect on a 170-million-person labor market would be limited, and that any shortages would create incentives for higher wages and automation rather than persistent economy-wide gaps.
