Enforcement and Removal Operations (EROs)
A division of ICE responsible for enforcing federal immigration laws and ensuring the removal of immigrants who are in the country illegally. These special task forces are strategically placed and mobilized in order to carry out their operations—often called “raids”—to locate, apprehend, and remove undocumented immigrants. ERO can also refer to the act of removing an undocumented immigrant from the country.
