San Mateo County funds Faith in Action to operate a 24/7 rapid-response hotline (203-NO-MIGRA) for residents to report ICE contact or sightings, and provides family preparedness plan templates and Know Your Rights materials in English, Spanish, Chinese, Portuguese, Tagalog, and Tongan, along with rapid-response posters and cards. In June 2025, the county dedicated $1.75 million towards immigration legal services, including support of the organization that manages the rapid response hotline.
