I-9 Subpoenas and Notices of Inspection: What Employers Need to Know When DHS and HSI Come Knocking

Almonte Law

Introduction

If your company receives a Notice of Inspection (NOI) or an I-9 subpoena from the Department of Homeland Security (DHS) or Homeland Security Investigations (HSI), you are no longer dealing with routine HR compliance—you’re now on federal law enforcement’s radar.

As a federal criminal defense attorney, I’ve seen firsthand how quickly a seemingly civil immigration audit can escalate into a full-blown criminal investigation. Understanding your rights, obligations, and risks is critical in the first 72 hours.


What Is a Notice of Inspection (NOI)?

A Notice of Inspection (NOI) is a formal letter issued by HSI notifying an employer that their Form I-9 records will be audited. It triggers the beginning of a DHS worksite enforcement action.

Employers have only 3 business days to provide the following:

  • Form I-9s for current and past employees (typically 3 years back)
  • Supporting documents (e.g., payroll records, hiring rosters)
  • Business formation records and E-Verify logs

👉 Pro Tip: Do not treat an NOI as routine. It often precedes a subpoena or search warrant. Or in some cases, they are done simultaneously.


What Is an I-9 Subpoena?

An I-9 subpoena is an administrative tool used by HSI to obtain additional records beyond Form I-9s. This includes:

  • Tax documents and payroll reports
  • Employee files
  • Hiring practices and communication records

The subpoena may cite 8 U.S.C. § 1225(d) and 8 C.F.R. § 274a.2, and can be part of a civil audit—or the early stages of a criminal investigation for:


Top Red Flags That Trigger Criminal Investigations

HSI may escalate your case based on:

  • Multiple I-9 forms with clearly falsified or missing documentation
  • SSN mismatches or patterns of document fraud
  • Labor subcontractors used to avoid direct hiring liability
  • Previous ICE warnings or prior audits
  • Anonymous tips or whistleblowers

If they suspect willful violations, HSI may refer your case to the U.S. Attorney’s Office for federal prosecution.


How a Federal Criminal Defense Attorney Can Help

Responding to an NOI or I-9 subpoena without legal guidance is a high-risk move. Here’s how experienced federal counsel can help protect your company and leadership:

1. Strategic Document Review and Subpoena Response

  • Ensure timely, narrowed compliance
  • Protect privileged communications
  • Push back on overbroad requests

2. Internal I-9 Audit and Risk Assessment

  • Identify and correct errors
  • Preserve records and document good-faith efforts
  • Develop internal compliance protocols

3. Employee Interview and Raid Preparation

  • Train staff on their rights
  • Prepare response plans for search warrants or visits
  • Serve as the point of contact with agents and prosecutors

4. Criminal Exposure Analysis and Early Intervention

  • Evaluate potential charges and negotiate early
  • Explore non-prosecution agreements or deferred prosecution
  • Shield ownership and executive leadership from liability

What to Do If You Receive an I-9 Subpoena or NOI

  1. Call a federal criminal defense attorney immediately
  2. Do not speak to HSI agents without legal counsel present
  3. Preserve all documents and emails related to hiring practices
  4. Do not alter or destroy any Form I-9s
  5. Start your own internal audit with legal oversight

Final Thoughts: Stay Ahead of HSI Worksite Enforcement

I-9 audits are no longer just civil compliance checks. With HSI’s aggressive worksite enforcement strategy, every subpoena or NOI carries real criminal exposure.

If you or your client has received an I-9 subpoena or Notice of Inspection, early legal intervention is essential. These cases move fast, and what you do in the first few days can make the difference between a fine and a felony.
