Frisco operates under Texas Senate Bill 4, the 2017 anti-sanctuary law that bars local jurisdictions from limiting cooperation with federal immigration authorities and imposes personal penalties on non-compliant officials.
Texas SB 4 (Government Code Chapter 752) prohibits cities, counties, and law enforcement from adopting policies that restrict ICE detainer cooperation or limit officer questioning about immigration status. Frisco Police honor ICE detainers and may inquire about immigration status during lawful stops. Elected officials adopting sanctuary policies face civil fines up to $25,500 per day and potential removal from office. Collin County's conservative orientation and Frisco's compliance posture mean no sanctuary protections exist locally. Federal injunctions partially limited SB 4 but core cooperation mandates remain in force.
Officials or agencies refusing ICE cooperation face civil penalties up to $25,500 daily, removal from office, and Class A misdemeanor charges for sheriffs blocking detainer compliance.
