How KCSO Responds to Reports Involving ICE or Federal Immigration Activity

Community members have shared questions about safety, trust, and how local law enforcement interacts with federal immigration agencies. The King County Sheriff’s Office (KCSO) understands that these issues can create fear and uncertainty, especially for immigrant and mixed-status families.

We outline how we address these concerns, clarify the responsibilities of our deputies, and explain the steps we take to ensure our work remains transparent, community centered, and separate from federal civil immigration enforcement.
