Immigration Arrests in the Interior of the United States: A Brief Primer [November 14, 2019] [open pdf - 642KB]
From the Document: "U.S. Immigration and Customs Enforcement (ICE), a component of the Department of Homeland Security (DHS), is primarily responsible for immigration enforcement in the interior of the United States. ICE has substantial authority to arrest and detain non-U.S. nationals (aliens) identified for removal because of immigration violations. In recent years, there has been a marked increase in arrests and removals conducted by ICE. Sometimes these arrests have been conducted as part of large-scale 'sweeps' or 'raids' involving the arrest of hundreds of individuals. These large-scale enforcement actions have prompted complaints by some that they instill panic and fear in immigrant communities, along with criticism that they may lead to separation of U.S. citizen children from their unlawfully present alien parents. In response, ICE asserts that it does not conduct raids indiscriminately, but targets those who have criminal charges or shown 'blatant disregard for U.S. immigration laws.' The agency also argues that these enforcement actions are safely executed and deter future immigration law violations. This Legal Sidebar provides an overview of ICE's power to conduct arrests and other enforcement actions."
