US immigration enforcement trends

In July 2026, U.S. Customs and Border Protection reported that the Border Patrol released no illegal immigrants for the 14th month in a row, with apprehensions falling to 9,848—about a 94 % drop from the previous administration’s average. Officials linked the decline to the Secure America Act, a $70 billion funding package signed by President Donald Trump that boosted Border Patrol resources and technology.

A few weeks later, a report cited by Judicial Watch highlighted a sharp rise in unauthorized migration under President Joe Biden’s policies. The analysis claimed that illegal entries had roughly doubled since 2019, reaching an estimated 4.3 million by the end of Biden’s term, and that the overall U.S. unauthorized immigrant population stood at about 15.8 million in mid‑2024. The increase was attributed to expanded humanitarian parole programs and broader aid to Central America, prompting political backlash.

Together, the snapshots illustrate a rapid swing in U.S. immigration dynamics: a period of stringent enforcement and low apprehensions under Trump, followed by a reported surge in illegal entries and broader humanitarian measures under Biden.
