Arrests of legal U.S. residents and even citizens in connection with immigration proceedings have increased sharply during the Trump administration, reflecting substantial changes in enforcement priorities, the legal environment, and agency behavior.
The available data, significant cases, and points of contrast with previous administrations are detailed below.
| Aspect | Obama (2009-2016) | Trump (2017-20, 2025-) | Biden (2021-2024) |
|---|---|---|---|
| Enforcement Targeting | Serious crime/recency | All removable persons | Serious crime/public safety |
| Discretion for Legal Residents | Frequent | Rare or none | Moderate |
| Routine Check-in Arrests | Less common | Vastly increased | Reduced |
| Legal Residents/Citizens Detained | Few documented cases | Documented, hundreds | Rare |
| Detention Population (ICE) | 30,000-45,000 | Record: 66,000+ | Around 20,000-35,000 |
The Trump administration’s departure from previous norms led to an unprecedented rise in immigration-related arrests of legal residents and wrongful detentions of U.S. citizens, driven by policy, statutory changes, and greatly increased enforcement resources. [1][3][11]
