How does interior immigration enforcement affect how undocumented immigrants describe their interactions with state and societal institutions? Although there is some evidence that points to a broad range of chilling effects that result when local law enforcement officials work with U.S. Immigration and Customs Enforcement (ICE) on federal immigration enforcement, there is no systematic study that collectively examines the impacts that may result with such enforcement efforts. We situate our paper as evidence of the homeland security state and show how contemporary interior immigration enforcement subjugates undocumented immigrants in nearly all facets of their interactions with state and societal institutions. To illustrate this, we embedded an experiment in a survey (n = 594) drawn from a probability-based sample of undocumented immigrants. When respondents are told that local law enforcement officials are working with ICE on federal immigration enforcement, they report that they would be less likely to report crimes they witness or are victims of to the police, use public services that require them to disclose their personal contact information, do business that requires them to disclose their personal contact information, and participate in public events where the police may be present, among other main findings.
