What best describes an "ICE raid"?

The description of an "ICE raid" as an operation by ICE agents at a given location is accurate because such raids are typically conducted to enforce immigration laws, often focusing on the apprehension of individuals suspected of being in the United States without legal status, as well as employers who may be violating immigration laws. These operations are usually planned and executed in response to intelligence regarding illegal immigration activities or violations.

ICE raids are significant in that they demonstrate the agency’s role in immigration enforcement and can occur in various settings, including workplaces, residences, and community events. This operational aspect is fundamental to understanding ICE's mandate and the scope of its activities. The other options, such as routine checks of immigration applications, community outreach events, and a judicial review of immigration cases, do not align with the definition or the nature of what constitutes an ICE raid, as they pertain to different functions within the immigration system.
