High-profile U.S. Immigration and Customs Enforcement operations across the country underscore how rapidly moving and emotionally-charged immigration enforcement actions can be. Planning in advance for how your agency will respond if federal agents contact or involve employees in an enforcement action can be critical to managing risk and maintaining calm. Below are key legal principles and best practices to consider as your agency develops its action plan.
Immigration Enforcement Visits at the Worksite
Immigration enforcement officers may appear at a public agency workplace seeking access to facilities or individuals. Employees should remain calm, respectful, and professional, but they should also understand that they generally may not volunteer information or consent to the officers accessing nonpublic areas absent an appropriate warrant.
If immigration officers arrive at the worksite, agencies should follow these general principles:
- Request identification. Agencies may ask officers to identify themselves, present their credentials, and explain the purpose of the visit.
- Refer the officer to a designated agency contact. Agencies should have a protocol directing immigration officers to a central office or designated agency official who is trained to review legal documents and coordinate with legal counsel. Frontline employees and supervisors should advise the agents that they are not authorized to receive warrants and direct the agents to the point person.
- Review warrants carefully before granting access to nonpublic areas. Absent exigent circumstances, immigration officers cannot enter a nonpublic area of the workplace without either (1) consent or (2) a valid, signed judicial warrant. Administrative warrants issued by the Department of Homeland Security or one of its branches do not authorize entry into nonpublic spaces. This is because administrative immigration arrest warrants authorize the arrest of a named individual, but not a search of facilities. By contrast, a judicial search warrant, signed by a judge or magistrate, may authorize law enforcement entry into private spaces to search the premises and seize evidence, but only for the purposes and locations identified in the warrant.
- Verify any asserted exigent circumstances. Exigent circumstances are situations where any delay in permitting officer access to restricted areas would pose a significant risk to the safety of employees or the public. If officers assert emergency circumstances, employees should not interfere with the enforcement action, but they should immediately notify the agency’s designated point of contact and legal counsel.
Employers who consent to immigration enforcement agent access to private or restricted work areas absent an appropriate warrant may face penalties of $2,000 to $5,000 for first violation and $5,000 to $10,000 for each subsequent violation. (Government Code § 7285.1.)
Document Requests by Immigration Enforcement
U.S. Immigration and Customs Enforcement may also seek access to personnel records, such as I-9s, payroll records, employee names, and other identifying information, and agency policies related to hiring and employment practices. As with in-person enforcement actions, agencies should carefully review these requests, because disclosing personnel information beyond what is required may result in an employee invasion of privacy claim in addition to the penalties described above. (See Gov. Code § 7285.2.).
- Identify the type of subpoena. Absent a valid subpoena or court order, agencies generally should not allow immigration officers to review or obtain employee records. Like search warrants, administrative and judicial subpoenas differ in the scope of access they confer on enforcement agents. It is important to recognize that such requests are distinct from a Public Records Act requests and should not be analyzed in the same manner.
- Administrative subpoenas or requests directly from immigration agencies typically require the production of specific, identified records, but do not permit broad access to files. Agencies are only required to produce the records that the administrative request specifically describes. Broad or vague requests—such as “all employee records”—are not appropriate.
- Judicial subpoenas, signed by a judge or magistrate, may compel testimony or document production more broadly.
- Route all requests through designated channels. The same point of contact who reviews search warrants should also be responsible for reviewing subpoenas. Agencies should have an internal process for reviewing subpoenas and warrants, involving agency leadership and legal counsel, before responding.
- Protect confidential information. Agencies should take care not to release any confidential employee information they are not specifically required to release pursuant to a valid request or subpoena.
In the event an employer must grant an immigration agency access to a current employee’s records, the law requires the employer to provide the employee advance notice of the inspection within 72 hours of receiving the federal notice of inspection. A template notice to employees can be found on the Labor Commissioner’s website. Within 72 hours of the inspection’s conclusion, the employer must also provide the employee notice of the inspection’s results, including any deficiencies identified in the employee’s documentation and the timeline for correcting them.
A Note on Work Authorization Requirements
Nothing about the above changes the fact that employers cannot employ individuals who lack valid authorization to work in the U.S. If an employee’s work authorization expires—even if their renewal is pending—the agency should not maintain the employee in paid status unless and until their work authorization is renewed.
California Labor Code section 1019.2 prohibits an employer from reverifying a current employee’s employment eligibility at a time or in a manner not required by federal law. This prohibition does not include communications with an employee whose work authorization has expired or is set to expire in the near future. Rather, the law prohibits spontaneous demands that employees reestablish their authorization to work.
Conclusion
Preparation is key. California public agencies should train staff on how to respond to immigration enforcement contacts, designate specific points of contact, and ensure leadership understands how to review warrants and subpoenas. When in doubt, pause, verify, and consult counsel before granting access to the workplace or producing documents to federal immigration agents.
