Current I-9 enforcement activity is rising with no signs of slowing down. It is the deliberate outcome of structural policy changes, expanded ICE staffing, and aggressive agency mandates.
In Part 3 of our 4-part series, we analyze the key regulatory pivots driving today’s compliance realities. Most notably, the March 16, 2026 update to the ICE fact sheet reclassifying routine Form I-9 paperwork errors into substantive violations—eliminating the 10-business-day correction window. Below, we explore how these federal directives and state-level mandates directly impact your daily HR operations.

Federal Government Actions Since April 2025
The second Trump administration's immigration enforcement agenda was defined not by a single policy change but by a coordinated series of legislative, regulatory, operational, and enforcement initiatives. Taken together, these actions reveal a comprehensive strategy designed to remove unauthorized aliens from the United States, expand enforcement capacity, increase employer accountability, and improve the federal government's ability to identify and investigate potential violations.
For employers, understanding these developments is essential because many of them continue to influence compliance obligations and workforce planning decisions.
Legislative and Funding Initiatives
The foundation for expanded enforcement was established through significant federal funding commitments. In 2025, the Trump administration secured unprecedented resources for immigration and border enforcement activities as part of the One Big Beautiful Bill (signed on July 4, 2025). It provided agencies with the personnel, technology, and operational capabilities and most importantly, an additional $170 billion in funding to sustain elevated enforcement levels. In January 2026, ICE announced that its staffing grew by 120%, adding more than 12,000 new officers.
Importantly, this funding supported recruitment efforts that substantially increased agency staffing which in turn enabled the agencies (ICE, Homeland Security, etc.) to ramp up enforcement actions including NOIs and, more prominently, workplace raids. These investments matter because enforcement capacity historically serves as one of the strongest predictors of future audit activity.
Unlike temporary enforcement campaigns, this agency workforce expansion creates the infrastructure necessary for long-term operational activity. Employers should therefore view recent enforcement trends as part of a sustained strategic initiative rather than a short-term surge.
Main Policy Changes
Several policy developments significantly altered employer compliance responsibilities. Among the most consequential was the revision of inspection guidance affecting how documentation errors are categorized during audits.
Of particular importance to employers is the ICE fact sheet, updated on March 16, 2026, which reclassified common I-9 entry errors (missing date of birth, missing date of hire, failure to date Sections 1 or 2) from "technical" to "substantive" violations. Doing so eliminated the 10-business-day correction window for fixing these errors. Substantive errors have no correction window.
By reclassifying these errors, ICE seems to be trying to motivate employers to review existing Form I-9s and identify employees who needed to be verified or terminated because they could not present evidence of their continued ability to work in the U.S. Rather than take on the entire nationwide business community directly, the administration chose a path that motivated employers to self-police. This allows ICE/HSI to focus enforcement resources on specific industries identified early this this paper.
The distinction between technical and substantive violations has always played a critical role in enforcement proceedings because it affects an employer's ability to correct deficiencies before penalties are assessed. Recent guidance suggests a narrower interpretation of what constitutes a correctable error, increasing potential exposure for employers whose documentation processes lack consistency.
Program Terminations and Work Authorization Disruptions
Few developments generated more uncertainty for employers than changes affecting employment authorization programs. Actions affecting humanitarian parole recipients, TPS beneficiaries, and certain visa categories created significant workforce planning challenges throughout multiple industries.
Many employers discovered that they now needed to monitor federal court rulings, ICE (and other agency) announcements and policy updates in real time to determine whether employees remain authorized to work. For organizations employing large populations of affected workers, compliance became intertwined with workforce continuity planning.
The situation highlighted a broader reality: employment authorization risk now extends well beyond the initial hiring process. Employers must increasingly monitor changes occurring long after an employee has started work.
In addition, ICE eliminated automatic extensions for many renewal applicants which increased the likelihood that employers would need to monitor work authorization expirations more actively. Organizations that previously relied on lengthy extension periods suddenly faced shorter compliance timelines and more frequent reverification obligations.
Collectively, these changes transformed Form I-9 compliance from a relatively static process into an ongoing workforce-management responsibility.
Department of Labor Enforcement Initiatives
While ICE received much of the public’s attention, the Department of Labor also expanded enforcement activity. Programs targeting H-1B compliance, most notably, Project Firewall, signaled growing federal interest in ensuring that employers meet, and sufficiently document, all obligations associated with employment-based visa programs.
Enhanced investigation authority, targeted compliance reviews, and increased coordination among agencies created additional scrutiny for organizations employing foreign national workers.
Employers sponsoring H-1B, L-1, and other visa categories should expect intensified oversight and therefore must ensure that petition documentation, job descriptions, compensation records, and worksite information remain current and accurate. Increasingly, immigration compliance is being evaluated holistically rather than through isolated regulatory programs.
State-Level Developments Add Complexity
Federal enforcement activity was accompanied by state-level developments. Thompson Reuters reports that since April 2025, several states have expanded immigration-related employment obligations through broader E-Verify mandates, enhanced cooperation with federal immigration authorities, loss of business licenses associated with failure to comply with E-Verify obligations or employing unauthorized aliens, and proposals limiting access to employment-related benefits.
Florida and Tennessee have been among the most active states, while Idaho, Indiana, Kansas, Montana, and Texas considered legislation that would further expand mandatory employment verification requirements. In addition, several other states have E-Verify mandates and the list keeps growing.
For employers operating across multiple states, the resulting patchwork of obligations creates substantial administrative complexity. Processes that satisfy requirements in one jurisdiction may be insufficient in another. As additional states consider workforce verification mandates, organizations may find it increasingly efficient to adopt nationwide compliance standards rather than maintain multiple regional approaches.
A Year of High-Profile Enforcement Actions
Since April 2025, ICE, DHS, and the DOJ have demonstrated a renewed commitment to workplace immigration enforcement. Several enforcement actions became defining moments during the first year of implementation. Activity such as the aforementioned large-scale construction-site raids in Tallahassee, Florida (100+ arrests), the Glenn Valley Foods meat-processing raid in Omaha, Nebraska (approximately 75–80 arrests), and widespread restaurant and hospitality inspections in the Washington, D.C. area (100 audit “visits” by DHS), are becoming more common. In rare cases, the DOJ has pursued criminal charges against individual employers such as the general manager of industrial coating company in El Cajon, CA. who was accused of harboring or knowingly employing unauthorized workers.
Worksite investigations affecting construction, hospitality, manufacturing, and service-sector employers received widespread media attention and demonstrated the scale of resources federal agencies are willing to deploy. These actions signal a broader shift toward combining traditional Form I-9 audits with high-visibility worksite enforcement operations and criminal investigations.
Key Takeaways
Federal actions taken since April 2025 suggest that enforcement activity is still expanding. Additional funding, agency staffing increases, enhanced data-sharing between agencies, new work authorization restrictions, and state-level E-Verify mandates indicate that employers should expect continued regulatory pressure rather than stabilization.
Organizations that treat recent developments as temporary policy shifts risk underestimating the structural changes occurring across the enforcement ecosystem.
With minor clerical errors now triggering immediate financial penalties, traditional paper-based or unmonitored compliance processes represent a direct liability. In our final installment in our series, we detail actionable steps for building an audit-ready infrastructure, establishing continuous compliance protocols, and securing executive buy-in.
