The landscape of employment eligibility verification in the United States is largely defined by Form I-9, a seemingly ubiquitous requirement for nearly every employer and employee. However, a nuanced legal perspective reveals that a minuscule fraction of the workforce might legitimately bypass this standard, a possibility that, while rare, underscores the historical evolution of immigration and employment law. According to Bruce Buchanan, a senior counsel at Littler, an employee might not require an I-9 if their hiring predates November 7, 1986, a date intrinsically linked to the Immigration Reform and Control Act (IRCA) of 1986. This "grandfather clause" offers a singular, increasingly anachronistic exception to a rule that otherwise applies to virtually every individual commencing employment in the U.S.
The Genesis of Form I-9 and the IRCA of 1986
To fully comprehend the specific exemption and its dwindling relevance, it is essential to delve into the origins of Form I-9. Prior to the Immigration Reform and Control Act (IRCA) signed into law on November 6, 1986, there was no federal requirement for employers to verify the employment eligibility or identity of their hires. Employers could, and often did, hire individuals without any legal obligation to ascertain their immigration status or authorization to work in the United States. This regulatory void contributed to a growing concern over undocumented immigration and its perceived impact on the American labor market.
IRCA was a landmark piece of legislation designed to address these concerns through a dual approach: it offered a pathway to legal status for millions of undocumented immigrants already in the country (an amnesty program) while simultaneously introducing employer sanctions for hiring unauthorized workers. Central to the employer sanctions provisions was the creation of Form I-9, the Employment Eligibility Verification form. Effective November 7, 1986, IRCA mandated that all U.S. employers must verify the identity and employment authorization of all new employees hired after this date. This pivotal shift placed a direct responsibility on employers to ensure their workforce was legally authorized to work, making the I-9 process an indispensable part of onboarding.
The "grandfather clause" thus emerged directly from this effective date. Any employee hired before November 7, 1986, was exempt from the I-9 requirement, as the law was not retroactive. They were "grandfathered in" under the previous regulatory framework, or lack thereof. This historical context illuminates why, for an employee to legitimately lack an I-9 today, their tenure with a single employer would need to stretch back nearly four decades, a scenario that has become exceedingly uncommon.
The Diminishing Rarity of the Grandfathered Employee
Bruce Buchanan’s observations during an August 11 webinar, where the question regarding long-tenured employees and Form I-9s was posed, highlight the extreme rarity of such cases in contemporary workplaces. Buchanan, with nearly two decades of experience in employment law, noted, "It’s going to be very rare that you’re going to be able to grandfather anybody in. I’ve been doing this 19 years. It was a lot more common 19 years ago than it is today." This statement encapsulates the demographic reality: employees with continuous employment at the same company for close to 40 years are a vanishing breed. While some industries or specific organizations might still harbor such long-serving individuals, their numbers are statistically insignificant across the broader U.S. labor market. The average job tenure in the U.S. has fluctuated but generally remains far shorter than four decades, with the Bureau of Labor Statistics reporting a median tenure of 4.1 years for all wage and salary workers as of January 2022. This statistical reality further underscores why the grandfather clause, while legally sound, is practically obsolete for the vast majority of today’s HR professionals.

The Rigorous Framework of I-9 Compliance
For the overwhelming majority of employers, the I-9 mandate is absolute and non-negotiable. The process is straightforward in principle but complex in execution, requiring meticulous attention to detail to avoid costly penalties. Upon hiring an employee, Section 1 of Form I-9 must be completed by the employee on or before their first day of employment. This section requires the employee to attest to their citizenship or immigration status. Subsequently, Section 2 must be completed by the employer within three business days of the employee’s first day of employment. In this section, the employer must physically examine original documents presented by the employee from the U.S. Citizenship and Immigration Services (USCIS) Lists of Acceptable Documents (List A, or a combination of List B and List C) to verify both identity and employment authorization.
The employer’s role extends beyond merely collecting documents. They must ensure the documents appear genuine and relate to the person presenting them, record document information accurately, and retain the completed Form I-9 for specific periods: either three years after the date of hire or one year after the date employment ends, whichever is later. Failure to comply with any of these requirements can lead to severe penalties.
Enforcement Trends and the Imperative of Due Diligence
The U.S. Immigration and Customs Enforcement (ICE) is the primary agency responsible for enforcing I-9 compliance. ICE conducts routine audits, often initiated through a Notice of Inspection (NOI), which informs employers that their I-9 records will be reviewed. Buchanan’s comments highlighted specific industries, such as hospitality and restaurants, as being particularly susceptible to these inspections. This focus aligns with historical enforcement patterns, where sectors traditionally employing a higher percentage of immigrant labor often face increased scrutiny.
Penalties for I-9 violations are substantial and can be levied for various infractions, including:
- Substantive violations: Errors in completing the form, missing forms, or accepting improper documents. Fines can range from hundreds to thousands of dollars per form.
- Paperwork violations: Minor technical errors that can often be corrected.
- Knowingly hiring or continuing to employ unauthorized workers: This is the most severe violation, carrying significant fines and potential criminal charges for employers and responsible individuals. Fines can be in the tens of thousands per unauthorized worker, coupled with potential jail time.
In fiscal year 2020, for example, ICE Homeland Security Investigations (HSI) made 1,362 worksite enforcement arrests and conducted 5,038 I-9 audits. While these numbers can fluctuate year to year, they consistently underscore ICE’s active role in ensuring compliance. The sheer volume of regulations, coupled with the severity of penalties, makes proactive I-9 management a critical component of any sound human resources strategy.
The Strategic Advantage of Self-Audits and Attorney-Client Privilege

Given the stringent enforcement environment, employment law attorneys, including Buchanan, strongly advocate for employers to conduct proactive I-9 self-audits. A self-audit involves an internal review of all I-9 forms to identify and correct errors before ICE initiates an inspection. This proactive approach can significantly mitigate potential penalties and demonstrate an employer’s good faith effort toward compliance.
Crucially, Buchanan emphasized the benefit of conducting such audits under attorney-client privilege. When an employer engages legal counsel to oversee or conduct the I-9 audit, the findings and corrective actions are generally protected from disclosure to government agencies, provided the privilege is properly established and maintained. This allows employers to uncover and rectify mistakes without immediately exposing themselves to liability. If ICE then conducts an audit, the employer can present a more compliant set of records, often leading to reduced fines or a more favorable outcome. This strategic protection is "well worth it," according to Buchanan, as it provides a safe harbor for employers to address compliance gaps.
A comprehensive I-9 self-audit typically involves:
- Reviewing all active I-9 forms: Checking for completeness, accuracy, and proper document verification.
- Identifying errors: Categorizing errors as substantive (missing forms, incorrect sections) or technical (minor omissions, typos).
- Correcting errors: Following specific USCIS guidance for making corrections (e.g., dating and initialing changes, attaching explanations).
- Implementing corrective action plans: Training staff, updating policies, and addressing systemic issues.
- Addressing potential unauthorized workers: If an audit reveals an employee might be unauthorized, seeking immediate legal counsel is paramount to navigate the complex legal and ethical implications.
Beyond the Grandfather Clause: Other Nuances and Exemptions
While the pre-IRCA grandfather clause is the primary exemption discussed, it’s important to acknowledge other, more common scenarios where an I-9 might not be required, or where specific rules apply:
- Independent Contractors: Form I-9 is generally not required for true independent contractors. The distinction between an employee and an independent contractor is critical and determined by various factors, not merely by label. Misclassifying an employee as a contractor to avoid I-9s can lead to severe penalties.
- Casual Domestic Employees: Those who perform domestic service in a private home on an intermittent or sporadic basis.
- Employees Not Performing Labor in the U.S.: Individuals hired to work exclusively outside the United States.
- Employees of Foreign Governments: Those who are accredited foreign government officials or their employees.
- Rehires: If an employee is rehired within three years of their original hire date, and their previous I-9 is still valid, employers may be able to reverify their employment authorization on the existing form, rather than completing a new one.
- Reverification: For employees with temporary work authorization (e.g., certain visa holders), employers are responsible for reverifying their employment authorization before it expires.
These nuances underscore the complexity of I-9 compliance and the need for HR professionals to stay continually informed about the specific requirements and updates issued by USCIS.
The Digital Evolution of I-9 and E-Verify
The I-9 process has also evolved with technology. While paper forms remain valid, many employers have transitioned to electronic I-9 systems. These systems can streamline the process, reduce errors, and improve record-keeping. The advent of E-Verify, an internet-based system operated by USCIS in partnership with the Social Security Administration (SSA), further modernized verification. E-Verify allows employers to electronically compare the information from an employee’s Form I-9 to data from U.S. Department of Homeland Security and SSA records to confirm employment eligibility.

E-Verify is currently voluntary for most employers in the U.S., but it is mandatory for federal contractors and subcontractors, and in certain states or for specific industries. The system provides a faster, more accurate way to confirm work authorization, but it also comes with its own set of rules and compliance obligations, including displaying posters, providing notice of tentative non-confirmations, and refraining from "pre-screening" job applicants. The continued push towards digitalization suggests that compliance will increasingly rely on sophisticated electronic tools and systems.
Implications for Human Resources Professionals
For HR professionals, I-9 compliance is a foundational responsibility that requires ongoing attention and expertise. The implications of non-compliance extend beyond financial penalties, potentially damaging an organization’s reputation, leading to operational disruptions, and diverting significant resources to legal defense. Best practices for HR departments include:
- Comprehensive Training: Ensuring all staff involved in the hiring process are thoroughly trained on I-9 requirements and updates.
- Robust Record-Keeping: Implementing secure and accessible systems for storing I-9 forms, whether physical or electronic.
- Regular Internal Audits: Proactively reviewing I-9s to catch and correct errors.
- Staying Informed: Regularly consulting USCIS resources, attending webinars, and subscribing to legal updates regarding I-9 policy changes.
- Legal Counsel: Establishing a relationship with experienced immigration or employment law attorneys for complex cases or audit support.
Conclusion: A Mandate That Endures
The notion of an employee not needing an I-9, while legally conceivable under the specific "grandfather clause" of IRCA 1986, has become an extreme rarity in the modern employment landscape. Bruce Buchanan’s insights underscore that for virtually all contemporary hires, the Form I-9 remains an absolute and critical requirement. As U.S. Immigration and Customs Enforcement continues to prioritize worksite enforcement, particularly in vulnerable sectors, the onus on employers to maintain impeccable I-9 compliance grows ever stronger. Proactive measures such as self-audits, especially those conducted under attorney-client privilege, are no longer merely advisable but essential components of a robust risk management strategy. The enduring mandate of Form I-9 is a testament to its role in upholding the integrity of the nation’s employment system, a responsibility that demands unwavering diligence from every employer.
