Use this checklist to help you understand your obligations under California law when an immigration enforcement agent comes to your workplace or issues a Notice of Inspection. California employers must comply with strict rules passed under the Immigrant Worker Protection Act which protects workers in the state from immigration enforcement while they're on the job. Under the Act, all employers, regardless of size, must limit Immigration and Customs Enforcement (ICE) agents' access to both the worksite and employee records, and they must follow notice obligations.
