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 U.S.? A comprehensive legal guide explaining Form I-9, reverification, e-Verify, document review, audits, and penalty risks in employing foreign workers, based on official sources. (uscis.gov)

For employers in the U.S. looking to hire foreign workers, one of the most critical aspects is the Form I-9 process , often mistaken for a simple "employment form," but in reality, a crucial federal compliance mechanism . According to USCIS, Form I-9 is used to verify the identity and work authorization of individuals hired in the U.S.; employers are also required to complete and retain this form for every employee hired after November 6, 1986. Therefore, I-9 is a fundamental legal obligation not only for immigrant workers but for virtually anyone hired in the U.S. ( uscis.gov )

The issue is even more sensitive for foreign workers. This is because a foreign worker's right to work may depend on their visa status, I-94 registration, EAD card, automatic renewal regime, or other immigration document. The employer's responsibility is not merely to conduct superficial checks at the level of "I saw the passport"; they must also know which document proves what, when revision is necessary, and when requesting unnecessary documents could lead to a risk of discrimination. The DOJ's Immigrant and Employee Rights Section explicitly states that practices such as requesting unjustified documents, imposing documents, and rejecting reasonably genuine documents in the I-9 and E-Verify processes may be unlawful. (DoJ)

Therefore, I-9 compliance is much more than just a technical task for human resources. Incorrect or late completed forms, improper reverification, failure to recognize automatically extended EADs, unnecessary document requests, or inadequate retention practices can all trigger both ICE audits and DOJ discrimination reviews . USCIS also explicitly emphasizes that I-9 violations can have civil and criminal consequences. (uscis.gov)

What is I-9 and why is it so important?

The primary function of Form I-9 is for the employer to verify both the identity and the legal right to work of the person they employ in the United States. Section 8 CFR 274a.2 stipulates that Form I-9 is the official means of fulfilling this verification obligation. This weakens employer defenses such as “I thought they had work authorization” because the system requires this verification to be in written and verifiable form. (Federal Register)

The critical point here is that I-9 does not give the employer a general "immigration officer" role. The employer assesses whether the submitted document reasonable and relevant to the employee; however, they are not required to conduct a document review at the level of a criminal investigation. At the same time, the employer cannot force the employee to submit a specific immigration document. The IER guidance clearly states that employees decide which documents to submit and that the employer cannot request more or different documents based on citizenship, immigration status, or national origin. (Department of Justice)

This distinction is particularly important in the employment of foreign workers. Completely different legal frameworks such as H-1B, TN, O-1, F-1 OPT, STEM OPT, H-4 EAD, TPS, asylum, refugee, and green card all converge on the same I-9 form from the employer's perspective. Therefore, a good I-9 system should include not only form completion but also document classification and date tracking. (uscis.gov)

How do Section 1 and Section 2 work in the I-9 process?

The employee must complete Section 1 of Form I-9 no later than the end of their first day of work. USCIS I-9 Central explicitly states this. The employer or authorized representative, however, must complete Section 2 within three business days of the employee's commencement of work . USCIS's Section 2 guidance and M-274 summary specifically emphasize this three-business-day rule. ( uscis.gov )

The rule is even stricter for very short-term employment. If an employee is hired for less than three working days, Section 2 must be completed no later than the first working day . This detail is often forgotten in practice; however, this error is quite common in short projects, event workers, day labor, or temporary assignments. (uscis.gov)

Another important detail is that the employer should not complete Section 2 before the employee completes Section 1. The form structure and USCIS guidelines require this order to be maintained. Especially in electronic onboarding systems, if the employer prepares Section 2 first or enters information on behalf of the employee in order to "speed up the process," it can create compliance problems later. (uscis.gov)

What documents can an employee submit, and what documents can an employer not request?

In the I-9 system, one of the employer's most fundamental obligations is to allow the employee to choose which documents to submit . According to the USCIS Acceptable Documents page, an employee can fulfill their obligation by submitting one List A document or one each of List B and List C documents. This structure is designed to prevent the employer from imposing specific documents. ( uscis.gov )

The DOJ IER is very clear on this: employers cannot request additional documents, demand different documents, or make specific documents mandatory based on citizenship or immigration status, and cannot refuse documents that appear reasonably genuine simply because they are not accustomed to them. These prohibitions are explained in detail on the IER FAQ page. In particular, requests such as "bring your DHS document," "bring your green card," or "bring your passport" unfair documentary practices . (Doctorate of Justice)

Therefore, the most dangerous reflex in companies employing foreign workers is the "let's ask for more paperwork if they're foreign" approach. The legally correct approach is the opposite: the employee chooses the appropriate combination of documents from the USCIS lists themselves; the employer only examines whether the submitted documents appear to be valid. When this principle is violated, the problem becomes not just I-9, but also an issue of immigration-based discrimination. (Department of Justice)

Rules for original documents, photocopies, and receipts

As a general rule, the employer the original document . Form I-9 instructions state that photocopies are generally not accepted; the only exception is a certified copy of the birth certificate. Therefore, completing Section 2 using only a PDF, phone photo, or photocopy is not safe. (uscis.gov)

Limited exceptions to this receipt documents. USCIS’s guide to receipts explains that valid receipts indicating a replacement for a lost, stolen, or damaged document may be provisionally accepted and 90 days . The same guide states that a similar 90-day logic applies in the context of reverification. (uscis.gov)

A common mistake employers make is assuming every USCIS receipt is a valid I-9 receipt. However, the receipt regime is a narrow and technical area. Just because a file has received a "receipt notice" doesn't always mean it's acceptable for I-9 purposes. The safest approach is to separately verify whether the document falls into one of the receipt categories accepted by USCIS (uscis.gov)

E-Verify and I-9 are not the same thing

Many employers in the U.S. believe that using E-Verify eases their I-9 obligation. This is incorrect. The USCIS explanation of E-Verify clearly states that E-Verify does not replace I-9; employers using E-Verify are still required to complete Form I-9 for each new employee. (uscis.gov)

E-Verify is essentially a web-based supplementary verification system. Some employers use it due to federal contracts, state regulations, or company policies; others don't use it at all. However, the main backbone in terms of legal obligation is always I-9. Therefore, a company with weak I-9 processes using E-Verify does not automatically make that company compliant. (uscis.gov)

This distinction is even more important for foreign workers. This is because E-Verify results do not eliminate the I-9 document obligation, nor do they remove the employer's prohibition against imposing documents or engaging in discriminatory behavior. The DOJ IER can conduct document discrimination investigations by evaluating both the I-9 and E-Verify processes together. (Doctorate of Justice)

Is remote document review possible?

Yes, but not as a general and unlimited right. USCIS's "Remote Examination of Documents" guidance states that only employers registered in good standing with E-Verifytheir own E-Verify hiring sites. This procedure does not completely replace the classic physical examination rule; it is a specific method that replaces it under certain conditions. (uscis.gov)

Employers using remote examinations also have additional retention obligations. USCIS M-274 summaries and the remote examination page emphasize that clear and legible copies of documents examined remotely must be retained. Therefore, the "shown on Zoom, that's enough" approach may be legally insufficient. (uscis.gov)

The most common mistake is that employers assume the old pandemic flexibilities are still the general rule. However, the safe rule today is: remote document review is only available under the alternative procedure recognized by the DHS and with the appropriate E-Verify status. Otherwise, physical review remains the norm. (uscis.gov)

When is reversal necessary?

One of the most critical areas for international workers in I-9 compliance the reverification process. USCIS M-274 explicitly states that for current employees with temporary work authorization, the employer must complete reverification before the work authorization expires. This process is now Supplement B (uscis.gov)

However, reverification is not required for every employee. USCIS U.S. citizens and noncitizen nationals ; furthermore, lawful permanent residents . In particular, reversing a green card simply because its physical card has expired is incorrect in many cases. USCIS's LPR (Lawful Permanent Resident) guidelines emphasize that a lawful permanent resident whose valid status is proven by a green card has the right to work regardless of the card's printed date. (uscis.gov)

Another important nuance in this regard is that the employee retains the right to choose their documents during the reverification process. The DOJ IER FAQ page states that employers cannot impose specific DHS documents during the reverification phase; if an employee presents an unexpired List A or List C document, this must be accepted. Therefore, just like with initial employment, reverification is not a place for document imposition. (Doctorate of Justice)

What should employers look out for with H-1B, H-4 EAD, F-1 STEM OPT, and other foreign employees?

In employing foreign workers, the employer's greatest responsibility is not to interpret I-9 in isolation from the relevant legal status. For example, while I-94 and petition deadlines are important for H-1B employees, separate EAD (Employer Admission Fee) regimes often apply to H-4 spouses; and for F-1 STEM OPT (Employer Admission Fee), EAD, school registration, and employer suitability are all relevant together. The employer doesn't need to handle the entire case like an immigration lawyer; however, they need to know which employee groups require deadline tracking and which documents affect workplace compliance. ( uscis.gov )

Employers often make two contradictory mistakes, particularly with EAD (Emergency Access to Foreign Work) employees: either they panic unnecessarily because the card is running out, or they assume it's automatically renewed and don't check at all. USCIS's I-9 Central resources explain that some EAD categories have an automatic renewal mechanism, while in others, the underlying status or filing date is also important. Therefore, the only reliable method for reviewing foreign employee files is category-based and date-based review. (uscis.gov)

How long should I-9 records be kept?

A crucial part of the I-9 obligation is the retention period. The USCIS I-9 page and M-274 guidance clearly state that employers must retain the I-9 for each employee for three years from the date of hiring or one year from the date of termination, whichever is later. (uscis.gov)

This rule makes the "it's already in the file system anyway" approach insufficient while the employee is still employed. Similarly, destroying the I-9 form as soon as the employee leaves the company can also be incorrect. The retention period often continues even after the employment relationship ends. Failure to submit the form at all during an I-9 audit can have consequences as serious as an incomplete form. (uscis.gov)

Can the employer correct their own mistakes?

Yes, USCIS allows employers self-audit and correct errors. USCIS's "Self-Audits and Correcting Mistakes" guide clearly explains how to make corrections: cross out the incorrect information, enter the correct information, date it, and initial it with the appropriate person's signature. Confidential deletion, destruction, or completely ignoring the document is not the correct method. (uscis.gov)

This topic is very important for employers because establishing a compliant internal remediation mechanism when I-9 errors are detected, rather than remaining passive, often reduces audit risk. However, discriminatory document requests should not be created during self-auditing, and the remediation logic should not be used to make old records invisible. (uscis.gov)

What happens if ICE surveillance is implemented?

According to ICE’s “Form I-9 Inspection” factsheet dated January 26, 2026, the inspection process typically begins with a Notice of Inspection (NOI) sent to the employer. The employer is required to submit I-9 records within three business days of this notification in most cases . ICE also states that if technical or procedural deficiencies are identified, the employer is generally given at least 10 business days to rectify them; however, substantive violations and uncorrected deficiencies may result in monetary penalties. ( ice.gov )

ICE's 2026 worksite enforcement statements also show that I-9 checks are actively being conducted and can have both civil and, in some cases, criminal consequences. Therefore, I-9 checks are not a rare risk that arose once in the past; it is a living area of ​​enforcement. (ice.gov)

How serious is the risk of fines and sanctions?

USCIS's "Penalties" page clearly states that I-9 and immigration-related employment violations civil and criminal violations . ICE also notes that I-9 audits can result in fines for substantive violations and uncorrected technical/procedural errors. Therefore, the risk isn't just "employing undocumented workers"; failing to complete the form at all, completing it late, making incorrect reverifications, or failing to submit records can also result in criminal consequences. (uscis.gov)

This risk is not just theoretical. ICE's announcements for 2025 and 2026 show that the I-9 audit and worksite enforcement line is active. Therefore, the employer's thought of "we are a small company, it won't affect us" is not safe. The audit logic doesn't only apply to large companies; small and medium-sized employers can also be subject to serious scrutiny, especially in sectors where systemic non-compliance is observed. (ice.gov)

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

One of the most challenging aspects of I-9 compliance is maintaining the non-discrimination obligation while simultaneously verifying immigration . The DOJ IER enforces the INA's anti-discrimination provision and specifically identifies four categories of prohibited behavior: discrimination based on citizenship status, discrimination based on national origin, unfair documentary practices in the I-9/E-Verify process, and retaliation. ( Doctorate of Justice )

This means that employers need to take I-9 seriously, but they can't do so simply by treating employees differently who look or have foreign accents. Requesting more documents, demanding different documents, making specific documents mandatory, or rejecting documents that appear reasonably genuine, can lead to discrimination reviews rather than I-9 compliance. The DOJ's 2025 resolution letters and FAQs show that this area is being actively pursued. (Department of Justice)

How should a secure compliance strategy be established for employers?

A robust I-9 system shouldn't be limited to a single form-filling habit. The company needs to manage at least the following elements together: deadline alerts for Section 1 and Section 2, a revision schedule, training on which employee groups don't require revision, acceptable receipts and automated renewal scenarios, record retention period, and a quick access mechanism during audits. USCIS M-274 is the primary resource guiding employers in all these areas. (uscis.gov)

In addition, employers using e-Verify need to establish a second line of check independent of I-9; employers using remote audits should remember that this is only valid under the DHS’s authorized alternative procedure. As the number of foreign workers increases, it is safest for the human resources team to receive periodic training in these areas and conduct internal self-audits when necessary. (uscis.gov)

Conclusion

In the U.S., I-9 compliance in employing foreign workers is not just a formality for starting employment, but a key area of ​​risk where the employer intersects with federal immigration and employment law. Timely completion of Form I-9, respect for the employee's right to choose their documents, only necessary revisions when required, not confusing E-Verify with I-9, correct interpretation of receipt and automatic renewal regimes, and proper record keeping for the correct durations are all essential. (uscis.gov)

The biggest mistake is viewing I-9 solely as a "check for undocumented workers." The real risks are far broader: form errors, failure to present records during audits, incorrect reverification, failure to recognize automatic renewals, improper use of remote inspections, and discriminatory document requests all create serious problems. A properly managed I-9 process protects the employer; a poorly managed I-9 process creates unnecessary and costly risks for both ICE and the DOJ. For any employer in the U.S. hiring foreign workers, the safest approach is to view I-9 not as a HR routine, but a corporate compliance policy . (ice.gov)
