The United States, long hailed as a “nation of immigrants,” faces a divisive period regarding immigration. What once seemed a shared heritage has now become a focal point of political tug-of-war.
Recent Trends in Immigration Policy
The Biden administration’s tenure saw an increase in migrant arrivals, leading to heightened political tension and public discontent akin to the response triggered by former President Donald Trump’s deportation strategies. Leading up to the 2024 presidential election, immigration remains a polarizing issue. According to a Pew Research Center survey, 51% of voters perceive illegal immigration as a “very big problem,” with opinions heavily split along party lines: 78% of Republicans and 27% of Democrats agree.
Trump has promised to counter what he terms an “invasion” of illegal immigration, pledging the country’s largest deportation efforts. His administration claimed nearly 3 million “illegal aliens” left the U.S. during the first year of his second term, with most departures being self-initiated.
Immigration Slowdown and Its Impacts
Trump’s policies have led to a significant decline in the U.S. immigration rate. For the first time in a decade, the country witnessed negative net immigration, according to estimates from the Brookings Institute. In 2025, net immigration ranged between -295,000 and -10,000, with similar trends anticipated for 2026.
The 2025 Census data highlighted a drop in net international migration, peaking at 2.7 million in 2024 and decreasing to 1.3 million by mid-2025. The trend is projected to further dip to around 321,000 in 2026.
This decrease impacts population growth, which slowed to 0.5% by July 2025, its lowest rate since the COVID-19 pandemic. Christine Hartley of the Census Bureau points to the decline in net international migration as a key factor.
The Implications of Reduced Immigration
Experts argue that reduced immigration could reshape the U.S. Demographer William H. Frey suggests the U.S. should continue to welcome migrants to avoid workforce aging and prevent population decline. Counteracting views come from Steven Camarota of the Center for Immigration Studies, who advocates for lower immigration.
Both Frey and Camarota have proposed future scenarios based on varying immigration levels. Frey presents zero, low, and high immigration scenarios. Meanwhile, Camarota discounts zero immigration but imagines low, medium, and high levels, utilizing Census Bureau projections.
Zero/Low Immigration Scenario
Frey predicts a shrinkage of the U.S. population to 312 million by 2051 with zero immigration, whereas low immigration levels would see growth to 345 million. Camarota’s estimates align closely with these projections.
According to Camarota and Census data, the working-age population could drop minimally under low immigration.
Medium and High Immigration Scenarios
With medium immigration, Camarota forecasts growth of 34.6 million people by 2060, while high immigration predicts a rise to 385 million. This could add young generations to the workforce, enhancing economic productivity. Camarota, however, is skeptical of significant demographic shifts, expecting minimal change in working-age proportions. He notes that the U.S. would undergo aging regardless of immigration levels.
Immigration’s Broader Impact
Frey and Camarota also discuss immigration’s effects on the U.S.’s ethnic diversity. Increasing immigration levels mean increasing Hispanic and Asian population representation. With zero immigration, the foreign-born population would halve by 2051. Yet, all scenarios anticipate ethnic diversity increases.
Public Perceptions and Political Implications
Public opinion underscores the political divide. Mass deportations have seen decreasing support among Republicans. In 2025, 53% approved of Trump’s approach, yet by April 2026, only 52% of U.S. adults agreed Trump was doing too much.
Many Americans believe immigrants positively contribute to the nation’s culture and economy, despite division. Future elections may reflect these views, determining the country’s immigration strategy moving forward.
