Will stopping immigration cause labor shortages?

This is a substantive economic policy question that benefits from current data and expert analysis rather than a quick search. Let me look into current perspectives on this.## Short answer: Yes, in specific sectors—most economists find strong evidence that sharply restricting immigration does cause or worsen labor shortages, particularly in certain industries, though the picture is more nuanced for the overall economy.

Where the evidence is strongest: sector-specific shortages

Immigrant workers are heavily concentrated in particular industries, making those sectors especially vulnerable when immigration is curtailed:

Real-time evidence from 2025 policy changes

Recent data on the current U.S. immigration crackdown offers a natural experiment. Economists have found that labor force growth has been "stagnant" in states like Texas and Florida with high immigrant arrests per capita, while "low-arrest" states have seen positive labor force growth in 2025—the foreign-born labor force in low arrest-to-population states increased while the labor force in high-arrest states flatlined. Similarly, job growth among industries that rely more heavily on undocumented immigrants has been "significantly weaker" than in the rest of the private sector—job growth in hotels, restaurants, construction and home health aides has been flat since the start of 2025, while growth slowed less sharply elsewhere.

The construction sector specifically shows wage pressure consistent with shortages: the construction industry, which already suffers from labor shortages, is at risk of wage inflation—average wage growth in July approached 8%, nearly double the national average, with immigration actions potentially deepening workforce shortages and driving up costs.

The counterargument: "Americans will fill the gap"

The Trump administration has argued the opposite—that restricting immigration will benefit native workers. Vice President JD Vance and other officials have argued that limiting immigration will raise wages and create more job opportunities for U.S.-born workers, contending that these workers are available to counter labor shortages, with White House spokesperson Abigail Jackson stating there is "no shortage of American minds and hands to grow our labor force."

However, actual 2025–2026 data has not supported this claim. Analysis found that the labor force participation rate for native-born workers fell in the fall of 2025 and remains lower than forecasted, with native-born employment indicators continuing to stagnate or materializing worse than forecasted trends.

Why native workers often don't fill these jobs

Part of the explanation is that immigrants and native-born workers aren't perfect substitutes, especially in physically demanding, low-wage jobs. As one Virginia farmer put it, "People in the city aren't coming back to the farm to do this kind of work... It takes a certain type of person to bend over in 100-degree heat."

Broader economic consequences

Beyond specific sectors, economists project macro-level effects. Federal Reserve Chair Jerome Powell cited immigration policy as a factor behind the slowdown in the labor supply in 2025. Projections suggest net change in the immigrant population over age 16 will be in the range of -525,000 to 115,000 in 2025, down from 2.2 million in 2024, which would reduce GDP growth in 2025 by 0.3-0.4 percentage points as potential employment growth is cut from 140,000-180,000 jobs a month in 2024 to just 10,000-40,000 jobs a month in the second half of 2025.

A longer-term structural factor compounds this: immigration is the driving force behind America's labor supply growth, accounting for about half of labor force growth each year for the past three decades—with the U.S. population aging and deaths expected to exceed births by 2030, immigration is becoming an increasingly integral component of America's labor supply.

Important caveats and nuance

The picture isn't unanimous. Some economists, like Harvard's George Borjas, have raised concerns about immigration's negative effects on low-skilled native wages, while others such as Giovanni Peri have found that immigration has only a minimal effect on the wages of U.S.-born workers. One labor economist suggested the current crackdown could actually be beneficial if paired with reform: the crackdown on illegal immigration could be a good thing if it leads to permanent solutions—"If you can stop undocumented immigration, then great. This is a great time to work on comprehensive immigration reform," asking "Where is there a scarcity of workers and how do we address those legally instead of illegally?"

Bottom line: The weight of current economic evidence—from the Federal Reserve, academic economists across the political spectrum, and real-time 2025 labor market data—suggests that sharply restricting immigration does create or worsen labor shortages, particularly in agriculture, construction, hospitality, and caregiving, with native-born workers generally not filling the gap at the scale or speed needed. The effects also appear to feed into higher prices and slower GDP growth, though the long-term outcome partly depends on whether restrictions are paired with other policy changes (like expanded legal pathways) or implemented in isolation.
