Americas foreign-born population has undergone a dramatic and historic decline during the first year and a half of President Donald Trumps second term, underscoring the profound impact of restoring serious border security and immigration enforcement after years of deliberate neglect.
According to the Gateway Pundit, a new analysis from the Center for Immigration Studies (CIS) finds that the foreign-born population fell from roughly 53.3 million in January 2025 to 50.5 million in July 2026. This estimated drop of 2.9 million people includes naturalized citizens, lawful permanent residents, long-term temporary visitors, and illegal immigrants, marking a sharp reversal from the explosive growth seen under Joe Bidens open-border agenda.
CIS preliminarily estimates that the illegal immigrant population alone shrank by about 2.3 million, declining from approximately 15.8 million in January 2025 to 13.5 million in July 2026. The best data we have shows an enormous decrease in the total foreign-born population, said Steven Camarota, CIS director of research and the reports lead author.
Camarota noted that the bulk of the decline appears to have occurred among illegal immigrants following President Trumps restoration of border security and interior immigration enforcement. The change represents an astonishing turnaround from the Biden years, when lax policies and ideological posturing replaced basic law and order.
CIS previously reported that the total foreign-born population increased by approximately 8.3 million during the four years preceding President Trumps return to office. In just 18 months, President Trump appears to have reversed more than one-third of that massive increase, demonstrating what a determined administration can accomplish when it prioritizes American sovereignty.
The organization concluded that net migrationthe number of people entering the country minus those leavingwas negative during this period. The Census Bureau has separately reported a dramatic slowdown in net international migration, reinforcing the picture of a nation finally regaining control of its borders.
Federal estimates show net migration falling from 2.7 million in 2024 to 1.3 million in 2025, with a projected decline to approximately 321,000 in 2026 if current trends continue. Census officials attributed the reversal to both fewer arrivals and increased emigration, a pattern entirely consistent with tougher enforcement and the end of the catch-and-release mindset.
This is what happens when America finally has a president willing to enforce the law. As The Gateway Pundit reported in August 2025, the foreign-born population had already fallen from 53.3 million in January to approximately 51.9 million in Junemarking the first sustained decline in decades.
By October, The Gateway Pundit reported that the decline had reached approximately 2.2 million, driven by President Trumps secure border, stepped-up enforcement, and voluntary self-deportations. The contrast with the Biden regime could not be more dramatic, as one administration invited chaos while the next insisted on order.
In December 2023, The Gateway Pundit reported that the foreign-born population had reached an all-time record of 49.5 million after rising by approximately 4.5 million during Bidens first three years in office. By March 2024, the foreign-born population had climbed to approximately 51.6 million, or 15.6 percent of the entire country, following the largest two-year increase ever recorded.
Joe Biden opened the floodgates. President Trump shut them.
Historical Census Bureau figures show just how extraordinary the current decline is, especially when viewed against nearly a century of data. The Census Bureau reported that the foreign-born population declined from 14.2 million in 1930 to 10.3 million in 1950 before reaching 9.6 million in 1970.
President Trumps estimated 2.9 million reduction occurred in only 18 months, larger than the entire decline recorded during any single decade between 1930 and 1970, underscoring how swiftly firm leadership can reverse the damage of radical, open-border policies and restore a measure of control, security, and national cohesion.
