The Trump administration has expanded immigration enforcement to U.S. airports, where plainclothes Immigration and Customs Enforcement officers are increasingly arresting travelers with expired visas, including people awaiting immigration benefits and spouses of U.S. citizens. Immigration lawyers said the arrests reflect a broader change in enforcement priorities. Shannon Shepherd, vice chair of the American Immigration Lawyers Association's Chicago chapter, said she now advises clients with pending immigration cases to avoid domestic air travel. The reported expansion builds on a 2025 information-sharing arrangement under which the Transportation Security Administration alerts ICE when travelers identified in immigration enforcement databases pass through airport screening. The expansion also follows broader efforts to widen immigration enforcement locations.
