I-9 Compliance Process for Employers in the US: Legal Responsibilities in Hiring Foreign Workers

How does the I-9 compliance process work for employers in the US? A comprehensive guide explaining Form I-9, E-Verify, reverification, document selection, audit, and penalty risks in employing foreign workers, based on official sources.

For employers in the U.S. seeking to hire foreign workers, one of the most critical compliance requirements the Form I-9 process. Many companies view the I-9 as merely a human resources entry document; however, legally, the I-9 is central to the employer's the identity and work authorization According to USCIS, Form I-9 is used to verify the identity and work authorization of individuals hired in the U.S.; furthermore, all employers are required to complete and retain an I-9 for every employee hired after November 6, 1986. Therefore, the I-9 is not just a "foreign worker form"; it is a fundamental federal obligation for every employee hired in the U.S. (uscis.gov)

This obligation is even more significant for foreign workers, as a foreign worker's authorization to work often depends on their status, visa, EAD, I-94, or a specific immigration petition. Employers reverification , track document validity, and maintain I-9 records for the correct durations, not only during the hiring process but also, in some cases, afterward. USCIS's M-274 Employer Manual and Form I-9 instructions explicitly remind employers that errors related to I-9 can result in civil penalties. ICE also emphasizes in its 2025 and 2026 announcements that I-9 audits and worksite enforcement activities are actively ongoing. (uscis.gov)

What is the basic logic behind the I-9 process?

The basic principle of the I-9 system is for the employer to verify the identity and work authorization of a newly hired person through documents permitted by federal regulations. Article 8 CFR 274a.2 states that Form I-9 is the official means of fulfilling this obligation and can be kept in paper or electronic format. The USCIS I-9 page also explicitly states that the form is used to assist employers in verifying the identity and work authorization of their employees. Therefore, I-9 is a recorded and auditable verification mechanism that weakens the employer's defense of "I thought they had work authorization." (Federal Register)

This system works in two stages. The employee must complete Section 1 no later than the first day of work. According to USCIS's current I-9 Central page, the employee must complete Section 1 by the end of their first day of work , but not before accepting the job offer. The employer or authorized representative must complete Section 2 within three business days of the employee starting work . If the employee is hired for a job lasting less than three days, Form I-9 instructions require Section 2 to be completed no later than the first business day. This timeline is where most I-9 errors occur; employers often assume that completing the onboarding paperwork within the first week is sufficient, whereas the rule is three business days. ( uscis.gov )

Which documents can an employer accept, and which cannot they request?

One of the most important rules of the I-9 system is that the employee chooses which document to submit . According to USCIS' Form I-9 and Acceptable Documents pages, an employee can prove their identity and authorization to work by submitting a single document from List A or one document each from Lists B and C. The employer's role is to assess whether the submitted document appears reasonable and relevant to the employee; the employer cannot compel an employee to submit a particular document. The DOJ Immigrant and Employee Rights Section also explicitly states that it may be unlawful for employers to request additional documents , impose a specific document , or refuse documents that appear reasonably true based on citizenship, immigration status, or national origin. ( uscis.gov )

One of the biggest mistakes in practice at this point is when employers direct employees to bring documents such as "bring your green card," "bring your EAD," or "bring your passport." Even if made in good faith, such requests are legally risky. The USCIS and DOJ line is clear: the employee chooses. The employer only reviews this document and writes it on the I-9. An employer saying, "You look like a foreigner, so bring your passport and work permit," can move the I-9 verification into the realm of discrimination. This is precisely why the IER offers specialized training and hotline support to employers. (uscis.gov)

Another critical rule is that photocopies are not accepted for physical examination . Form I-9 instructions and USCIS I-9 Central state that, as a rule, the employer can only accept the original document ; the only exception is a certified copy of the birth certificate . Therefore, Section 2 cannot be completed simply because an employee sent a PDF passport via email. The document must either be physically examined in person or the special remote examination procedure, which I will describe shortly, must be followed according to the rules. ( uscis.gov )

Are E-Verify and I-9 the same thing?

No. These two are often confused, but they are not the same. According to USCIS' M-274 guidance, even employers participating in E-Verify are still required to complete Form I-9 for every new employee. USCIS also defines E-Verify as a web-based system used to verify employees' eligibility for work . In other words, I-9 is the primary obligation; E-Verify is an additional verification tool used by some employers. ( uscis.gov )

This distinction is crucial in practice. An employer using E-Verify does not excuse I-9 errors. Similarly, correctly completing I-9 does not grant the right to not use the system if E-Verify is required. The USCIS “Special Rules for E-Verify Users” page clearly states that there are significant differences between E-Verify and I-9. Therefore, employers hiring foreign workers must first separately assess whether their industry and contracts require E-Verify and whether they have I-9 obligations. (uscis.gov)

Is remote document review possible?

Yes, but not for everyone and in every way. According to USCIS's "Remote Examination of Documents" and M-274 pages, employers registered in good standing with E-Verify can remotely review documents through the DHS-authorized alternative procedure on their E-Verify hiring sites . This procedure does not automatically replace classic physical review; it is subject to separate conditions. Furthermore, USCIS's relevant guidance states that employers choosing this method must retain clear and legible copies of the front and back of the documents. ( uscis.gov )

Therefore, a common mistake companies make is the approach of, “we’re working in a hybrid environment, so we’ll just do I-9 checks with video for everyone.” The legally safe statement is: remote inspections can only be used under the DHS’s authorized alternative procedure and if the necessary E-Verify requirements are met. Otherwise, the employer must revert to the physical inspection rule. Companies, especially those operating with old COVID flexibilities without knowing anything about the alternative procedure after 2023, are taking unnecessary risks. (uscis.gov)

When is reversal necessary?

One of the most sensitive issues in employing foreign workers is reversal , or the re-verification of work authorization. According to USCIS M-274, the employer no later than the date the employee's work authorization expires . This process is currently Supplement B . It is particularly important to actively monitor these dates for foreign workers with temporary work authorizations—for example, those holding certain EADs. (uscis.gov)

However, reverification is not required for every employee. USCIS explicitly U.S. citizens, noncitizen nationals , and Form I-551 (green card) . Similarly, it is often incorrect for an employer to say, "The date on the green card has expired, let's re-validate it." USCIS specifically emphasizes that a lawful permanent resident's right to work is independent of the physical expiration date of the card, and therefore, the employer should not subject someone submitting an I-551 to reverification. (uscis.gov)

Errors in this area are not merely technical; they also carry a risk of discrimination. DOJ IER and USCIS sources indicate that subjecting certain status groups to unnecessary reverification or targeting only foreign-looking employees can have unlawful consequences. In particular, with regard to lawful permanent residents, asylees, and refugees, employers may face both I-9 and discrimination investigations if the documentation logic is not well understood. (Department of Justice)

Why are automatic EAD extensions and duration calculations critical?

One of the most confusing areas in recent years regarding the employment of foreign workers is automatic EAD extensions. USCIS M-274 and I-9 Central sources indicate that automatic extension mechanisms exist for certain EAD renewals; in such cases, the employer can grant temporary employment authorization by considering the old EAD along with the appropriate I-797C receipt. However, this depends on the category and whether the renewal was issued on time. In some categories, particularly H-4 spouses, the underlying status history is also important. (uscis.gov)

The main risk for employers is either being completely unaware of this automatic renewal regime or assuming it applies to everyone. Even in current USCIS IER resolution summaries, employers are experiencing problems due to the incorrect rejection of automatically extended EAD + I-797C combinations. Therefore, employers who hire foreign workers should not simply say "the card has expired"; they should also check whether the document falls under the USCIS automatic renewal regime. Otherwise, they may unnecessarily dismiss the employee or, conversely, continue employing them even after the valid protection has expired. (Department of Justice)

Under what circumstances are receipt documents accepted?

USCIS I-9 Central regulates that some receipt documents may be temporarily accepted. For example, valid receipts issued for the replacement of a lost, stolen, or damaged document are generally 90 days . Similarly, in the context of reverification, USCIS explains that some receipts may be valid for 90 days after the expiry of the authorization. However, this area is limited; not every application receipt or every USCIS notice is considered an acceptable document. (uscis.gov)

A typical mistake here is for the employer to automatically accept any USCIS receipt or, conversely, to completely ignore any acceptable receipt. The categories of receipts valid under I-9 are numbered and have clear validity periods. Therefore, telling foreign employees to "bring your receipt if you have one" or "never with a receipt" can both be incorrect. The correct approach is to classify the document according to the USCIS receipt list (uscis.gov)

How long should I-9 records be kept?

One area where the I-9 obligation doesn't end with the hiring process is the retention period. The USCIS I-9 page and Questions and Answers section clearly states that employers must retain I-9 records for three years from the date of hiring or one year from the date of termination, whichever is later. The Form I-9 instructions reiterate this rule. Therefore, it may be unlawful for an employer to immediately destroy the I-9 simply because an employee has left the company. (uscis.gov)

This retention rule does not change whether it is kept electronically or in paper form; only the system controls change. USCIS M-274 emphasizes that employers may store I-9 forms in appropriate record systems, but must make them accessible at the time of an audit. In practice, incomplete retention has consequences at least as serious as incorrect completion; because the failure to present the form at all during an ICE audit is often considered a substantive/paperwork violation. (ice.gov)

What happens if ICE surveillance is implemented?

According to ICE's 2026 "Form I-9 Inspection" factsheet, the administrative audit process begins with a Notice of Inspection (NOI) to the employer. ICE also states that employers are generally required to submit company I-9 records within three business days of this notification . ICE statements from 2025 and 2026 clearly demonstrate the active use of I-9 audits in their worksite enforcement strategy. Therefore, I-9 is not merely a formality; it is a compliance area subject to regular audits. ( ice.gov )

An audit may reveal more than just minor technical deficiencies for the employer. USCIS’s penalties page and M-274 list civil and, in some cases, criminal penalties for violations such as paperwork violations , knowingly hiring , or knowingly continuing to employ unauthorized workers . ICE’s 2025 news reports also highlight multi-million dollar settlements and hundreds of thousands of dollars in fines; for example, an apple orchard in Washington agreed to pay $2.25 million in civil penalties for I-9 violations, while another firm in New Jersey faced fines exceeding $600,000 . These examples demonstrate that auditing is a risk with tangible consequences, not just a theoretical one. ( uscis.gov )

Why is the risk of discrimination on I-9 particularly serious?

In I-9 compliance, employers often believe the only risk is "employing undocumented workers." However, the DOJ's Immigrant and Employee Rights Section enforces the discrimination provision of the INA and conducts investigations, particularly citizenship status discrimination, national origin discrimination, unfair documentary practices , and retaliation . The DOJ IER page explicitly states that practices such as requesting additional documents, requesting different documents, rejecting documents that appear reasonably genuine, or making certain documents mandatory during the Form I-9 and E-Verify process may be prohibited. (Department of Justice)

Therefore, well-intentioned but overly “meticulous” employers are also at risk. For example, only requiring passports and immigration cards from employees with foreign names, forcing green card holders to undergo reverification every time their card expires, or systematically rejecting automatically extended EADs may open the door to discrimination investigations rather than I-9 compliance. The DOJ’s 2025 resolution summaries clearly show instances where employers encountered problems due to incorrectly rejecting extended EADs or imposing specific documents. It should be remembered that I-9 compliance impartial application . (Department of Justice)

How should a secure I-9 strategy be established for employers?

A robust I-9 compliance system shouldn't be limited to just a human resources employee filling out the form. First, the company should have an internal procedure managing its Section 1 and Section 2 calendars with automated reminders. Second, employee groups requiring and not requiring reverification should be separated; specifically, green card holders, citizens, and foreign workers with temporary work permits should not be treated the same. Third, a checklist should be used that adheres to current USCIS guidance in areas such as EAD renewal, automatic extension, I-94 deadline, and receipt acceptance. M-274 was written for this purpose and remains a fundamental reference for employers. (uscis.gov)

Employers should also be aware that using E-Verify does not replace I-9; and that using remote document review is only permitted on sites authorized by the DHS as an alternative procedure and with appropriate copy retention systems. Uninformed HR teams, even with good intentions, can create both I-9 violations and discrimination. Therefore, regular internal training, periodic self-assessments, and immigration counseling when needed are risk management, not expense, for companies employing foreign workers. (uscis.gov)

Conclusion

In the U.S., I-9 compliance is one of the most fundamental legal pillars for employers hiring foreign workers. This includes completing Section 1 on the first business day and Section 2 within three business days; allowing employees to choose their own documents; using original documents instead of photocopies as a rule; performing reverification only when necessary and for the correct individuals; and maintaining I-9 records for the correct duration and making them readily available for audit. I-9 and e-Verify are not the same; the I-9 requirement remains even if e-Verify is used. (uscis.gov)

The biggest legal risk isn't just "employing someone without a work permit." Errors such as incomplete forms, late completion, incorrect reverification, failure to recognize automatic renewal, imposing specific documents, and failure to present records during audits also carry a significant risk of fines and investigation. ICE's current workplace audit statements and DOJ IER practice demonstrate that this area is actively being monitored. Consequently, the I-9 is not a formality in the employment of foreign workers; it is the first and most visible compliance test where an employer comes into contact with immigration law. (ice.gov)
