Sanctuary City Policy refers to the practices adopted by some local governments in the United States to limit their cooperation with federal immigration enforcement. These policies are aimed at creating a safer environment for undocumented immigrants by reducing the fear of deportation and encouraging them to report crimes or access public services without fear of being targeted for their immigration status. This policy illustrates the tension between state and federal authority, as local governments assert their right to prioritize community safety and local law enforcement over federal immigration laws.
