Suffolk County operates under welcoming-county policies aligned with the New York State Trust Act, generally limiting local law enforcement cooperation with civil federal immigration detainers absent a judicial warrant.
Suffolk County government has adopted welcoming policies directing departments not to inquire about immigration status when providing services. The Suffolk County Police Department follows guidance consistent with the New York Attorney General's Trust Act framework, which restricts honoring civil ICE detainers without a judicial warrant or probable cause of a serious crime. County agencies generally do not collect immigration status for benefits eligibility unless required by law. Eastern town police departments set their own policies but operate within state attorney general guidance on civil immigration enforcement.
Officers or agencies violating county welcoming directives or state Trust Act guidance may face administrative discipline and civil liability for unlawful detention beyond state authority.
