Sanctuary jurisdictions are cities, counties, or states that limit their cooperation with federal immigration enforcement efforts. These jurisdictions typically do not honor requests from Immigration and Customs Enforcement (ICE) to detain individuals solely based on their immigration status, and may also restrict local law enforcement from inquiring about a person's immigration status. The aim of sanctuary jurisdictions is often to build trust between local law enforcement and immigrant communities, as well as to protect individuals from potential deportation and family separation. These policies have sparked debates and legal challenges at the federal and state levels.
