Immigration status is confidential, and the Employer will not divulge personal immigration status information of employees to any parties except as required for the immigration sponsorship process, as requested by employees in question, as required by law, as required to defend the Employer or its employees in legal proceedings, or as expressly stipulated in this Agreement. The Employer agrees to provide prompt written notice to the union if any government agency, including ICE, contacts the Employer for any purpose involving employees or if the Employer receives a search, arrest or administrative warrant, subpoena, or other request for documents.
