Immigration Compliance Checklist for Enterprise Companies (500+ Employees)

Enterprise companies sponsoring temporary work visas and employment-based green cards face compliance obligations from multiple federal agencies simultaneously: USCIS, ICE, DOL, and DOJ. For employers with 500 or more employees, the scale and complexity of these obligations creates substantial exposure. A single I-9 paperwork error, multiplied across hundreds of workers, can produce six- or seven-figure fines. An incomplete Public Access File can trigger a DOL investigation that cascades into USCIS petition revocations. This guide breaks down every major compliance area enterprise employers must manage in 2026, with current penalty amounts, retention rules, and key compliance considerations.

I-9 Verification and E-Verify: The Foundation of Employer Compliance

Every U.S. employer must complete Form I-9 for each person hired. The current edition (01/20/2025, valid through 05/31/2027) restored the statutory term "an alien authorized to work" in Section 1 and changed "gender" to "sex" on two List B document descriptions. For enterprise employers, the volume of I-9s processed annually means that even minor procedural inconsistencies become systemic violations when ICE audits the records.

Completion Deadlines and Remote Verification

Employees must complete Section 1 no later than their first day of employment. Employers must examine original documents and complete Section 2 within three business days of the hire date. Under the DHS alternative procedure (published July 25, 2023; effective August 1, 2023), employers enrolled in E-Verify in good standing may examine I-9 documents remotely via live video. The employer must receive clear document copies, conduct a real-time video session, check the "alternative procedure" box on the I-9, and retain legible copies for the full retention period. This option must be offered consistently to all employees at each E-Verify hiring site.

Reverification occurs in Supplement B before expiration of temporary work authorization. U.S. citizens are never subject to reverification. Lawful permanent residents who presented a standard Permanent Resident Card (Form I-551) are not subject to reverification; however, LPRs who presented temporary I-551 evidence (such as a temporary I-551 stamp or an I-797 receipt for Form I-751 or I-829) do require reverification when that temporary evidence expires. Reverifying documents that do not require it is a common trigger for anti-discrimination complaints.

E-Verify: Current Federal and State Requirements

E-Verify remains voluntary at the federal level for most private employers as of April 2026. Federal contractors and subcontractors subject to the FAR E-Verify clause (FAR 52.222-54), as well as employers in states with mandatory E-Verify laws, are required to use the system. The One Big Beautiful Bill Act (signed July 4, 2025) allocated approximately $170 billion for immigration- and border-related activities, including border infrastructure, detention, ICE operations, immigration courts, and technology, but did not include mandatory E-Verify provisions. Proposals to establish a mandatory Employment Eligibility Verification System (EEVS) with phased employer-size deadlines appeared in the Dignity Act of 2025 (H.R. 4393), introduced July 15, 2025, but that bill has not been enacted.

ICE Audit Penalties (Current as of January 2, 2025)

Civil penalties for I-9 violations, per the January 2, 2025 inflation adjustment (90 FR 1, Document No. 2024-31204), are as follows:

• Paperwork violations (substantive or uncorrected technical): $288 minimum to $2,861 maximum per violation
• Knowing hire or continuing to employ, first offense: $716 minimum to $5,724 maximum per violation
• Knowing hire or continuing to employ, second offense: $5,724 minimum to $14,308 maximum per violation
• Knowing hire or continuing to employ, third or subsequent offense: $8,586 minimum to $28,619 maximum per violation

ICE calculates fines using five statutory factors: business size, good faith effort, seriousness of the violation, whether unauthorized workers were involved, and prior violation history. For a company with 500 employees and a 10% error rate, paperwork fines alone can range from roughly $14,400 to $143,050 before aggravating factors.

Common enterprise compliance practices include:

• Deploying an electronic I-9 system with built-in audit trails and error flagging
• Storing I-9 forms separately from personnel files so that an ICE inspection is limited in scope
• Conducting annual internal self-audits using the same standards ICE applies; proactive self-audits receive maximum good-faith credit in penalty calculations
• Training every person authorized to complete Section 2, including remote hiring managers using the alternative procedure
• Tracking reverification deadlines through automated alerts

Enterprise employers managing 100+ visa holders often use a centralized compliance platform. Alma's enterprise immigration solution provides compliance tracking, deadline management, and real-time dashboards across an entire foreign national population.

LCA Compliance and the Public Access File

Every employer sponsoring an H-1B, E-3, or H-1B1 worker files a Labor Condition Application with the Department of Labor. The LCA creates binding obligations around wages, working conditions, and recordkeeping that persist for the entire duration of employment under that LCA.

Public Access File Requirements

The PAF must contain the signed, certified LCA, documentation of the wage rate paid, an explanation of the employer's actual wage system, prevailing wage documentation, notice/posting documentation, and a summary of benefits offered to U.S. workers in the same occupation. The file must be available within one working day of any request, including from members of the public, and maintained at the employer's principal place of business or the worksite listed on the LCA.

Wage Compliance

Employers must pay H-1B workers the higher of the actual wage (paid to similarly situated U.S. workers) or the prevailing wage for the occupation in the geographic area. Prevailing wages follow four OES-based levels published by DOL: Level 1 (17th percentile), Level 2 (34th percentile), Level 3 (50th/median), and Level 4 (67th percentile). Note: a DOL Notice of Proposed Rulemaking published in the Federal Register on March 27, 2026 proposes raising these to 34th/52nd/70th/88th percentiles; as of April 2026, the current levels remain in effect pending the rulemaking process. The wage-weighted H-1B lottery for FY 2027 (registration period: March 4 to 19, 2026) assigns four entries to Level 4 positions, three to Level 3, two to Level 2, and one entry for Level 1, per the DHS final rule on weighted selection (90 FR 60864, December 29, 2025; effective February 27, 2026). Wage level classification is now strategically significant beyond compliance alone.

LCA notices must be posted in two or more conspicuous locations at each worksite for 10 days (per 20 CFR 655.734(a)(1)(ii)(A)), on or within 30 days before filing. Electronic posting on a company intranet or a one-time email to employees in the same occupation satisfies the requirement per 20 CFR 655.734(a)(1)(ii)(B). Third-party worksite posting is mandatory; client refusal does not excuse the obligation.

Project Firewall: DOL's Enforcement Escalation

Project Firewall, launched September 19, 2025, represents the first time the Secretary of Labor has personally certified H-1B investigation initiation. As of November 2025, DOL reported at least 175 ongoing investigations with $15 million in assessed back wages (per a DOL statement to media). This program coordinates with DOJ, EEOC, and USCIS, meaning a single compliance gap can trigger multi-agency scrutiny. Penalties for willful LCA violations vary by severity: up to $9,624 per violation for general willful violations, and up to $67,367 per violation for willful violations that involve the displacement of a U.S. worker, plus back pay (per 20 CFR 655.810(b)). Debarment from the H-1B program for at least one year is available for willful violators, with longer debarment periods depending on severity.

The benching prohibition is a frequent target of DOL enforcement. Employers must pay H-1B workers the required wage for all nonproductive time caused by employment-related conditions, including lack of assigned work, company shutdowns, and time between client projects. This applies even during company-wide furloughs. The only exceptions are for nonproductive time at the employee's voluntary request unrelated to employment, or circumstances rendering the worker unable to work.

H-1B Worksite Changes and Material Change Amendments

For enterprise companies with employees across multiple offices, client sites, or remote locations, managing worksite compliance is one of the most operationally complex areas of immigration law.

When an Amended Petition Is Required

Under the Simeio Solutions guidance, any worksite change that moves the employee outside the area of intended employment (as defined at 20 CFR 655.715, typically the Metropolitan Statistical Area or the area within normal commuting distance) listed on the approved LCA requires both a new LCA and an amended H-1B petition. Other material changes triggering amendments include significant duty modifications, salary reductions below the approved level, and conversion from full-time to part-time. The employee may begin working at the new location upon filing.

Short-Term Placement Exception

The short-term placement rule (20 CFR 655.735) permits placement outside the approved area without a new LCA for up to 30 workdays within a one-year period. The 60-workday allowance applies only when three conditions are met: (1) the worker maintains an office or workstation at the permanent worksite, (2) the worker spends a substantial amount of time at the permanent worksite in a given year, and (3) the worker's residence or place of abode is located in the area of the permanent worksite and not in the area of the short-term placement. The employer must continue paying the required wage based on the permanent worksite, plus actual lodging, travel, meal, and incidental costs. Employers may not rotate workers on short-term placements to maintain continuous presence and avoid filing an LCA.

H-1B Dependent Employer Rules

An enterprise employer with 51 or more full-time equivalent employees becomes H-1B dependent when 15% or more of its FTEs hold H-1B status (INA § 212(n)(3)(A); note that smaller employers have different thresholds: more than 7 H-1B workers for 25 or fewer FTEs, and 13 or more H-1B workers for 26 to 50 FTEs). Workers are exempt from the additional attestation obligations if they earn at least $60,000 annually or hold a master's degree or higher in a specialty related to the employment (INA § 212(n)(3)(B)). Workers earning below $60,000 who lack such a degree are non-exempt and trigger the H-1B dependent employer's additional obligations: attestation of non-displacement of U.S. workers within 90 days before and after filing, secondary non-displacement at client sites, and good-faith recruitment of U.S. workers using industry-standard methods.

FDNS Site Visits: Preparation and Response

The Administrative Site Visit and Verification Program (ASVVP) is operated by the USCIS Fraud Detection and National Security Directorate. The H-1B Modernization Rule (published December 18, 2024; effective January 17, 2025) codified USCIS authority to conduct site visits under 8 CFR 214.2(h)(4)(i)(B)(2), making employer cooperation effectively mandatory. Refusal can result in denial or revocation of any H-1B petition for workers at the location in question.

What Triggers a Visit

Visits fall into three categories: random selection under the ASVVP, targeted selection using risk-based data analysis (focusing on high petition volumes, unusual worksite arrangements, prior compliance issues, or frequent amendments), and tips or referrals submitted through the USCIS online tip form or other reporting channels.

What to Expect During a Visit

FDNS officers typically arrive unannounced and spend 30 to 90 minutes on site. They verify the company's existence and operations, tour the facility, photograph workspaces, and conduct separate interviews with employer representatives, the beneficiary employee, and sometimes coworkers. Questions focus on job duties, salary, work location, reporting structure, and whether actual conditions match the filed petition. Officers may request W-2s, pay stubs, organizational charts, the complete I-129 file, and the Public Access File.

From January 20 through late December 2025, USCIS reported processing 29,000+ fraud referrals, investigating 19,300+ cases (finding fraud in 65%), completing 6,500+ site visits, and conducting 19,500+ social media checks.

Common organizational preparation practices include:

• Designating primary contacts at every office location who are available during business hours to respond to unannounced visits
• Training reception and front-desk staff to verify officer credentials (FDNS officers carry government-issued photo ID), escort them professionally, and contact the designated contact immediately
• Maintaining organized, searchable per-worker immigration files at each worksite, including the I-129 petition, approval notice, LCA, and PAF
• Briefing all foreign national employees during onboarding on what a site visit entails and that they are expected to answer questions truthfully and accurately
• Keeping immigration counsel accessible for real-time guidance if complex questions arise during a visit

USCIS Filing Fees for Enterprise Employers (2026)

Filing costs have increased substantially. The April 2024 fee rule introduced classification-specific I-129 base fees, and the September 2025 presidential proclamation added a $100,000 fee for certain new H-1B petitions.

Key fee components for H-1B petitions (large employers, 26+ FTE):

• I-129 base fee: $780
• ACWIA Training Fee: $1,500
• Fraud Prevention and Detection Fee: $500
• Asylum Program Fee: $600
• H-1B Proclamation Fee (from September 21, 2025): $100,000, applicable when the beneficiary is outside the U.S. without a valid H-1B visa, or when the petition requests consular or port-of-entry notification
• Premium Processing (effective March 1, 2026): $2,965

For a new cap-subject H-1B petition with premium processing where the proclamation fee applies, the total now exceeds $106,000. The proclamation fee does not apply to extensions or amendments for beneficiaries maintaining valid H-1B status inside the United States. However, the operative distinction is based on the beneficiary's location and visa status, not simply whether the petition is labeled "new" versus "extension." The proclamation is effective for 12 months (through approximately September 21, 2026) and is under active legal challenge in multiple federal courts. Petitions submitted without proof of required fee payment are denied at intake.

L-1 base fees are $1,385 for large employers. O-1 petitions cost $1,055 in base fees. TN and E-3 are $1,015 each. I-140 filing costs $715 plus the $600 Asylum Program Fee. Note: these totals do not include the $215 H-1B cap registration fee or the potential $4,000 Public Law 114-113 fee for employers with 50 or more U.S. employees of whom more than 50% hold H-1B, L-1A, or L-1B status.

Record Retention Requirements

Retaining records for the correct duration is a compliance obligation in itself. Both under-retention (missing records during an audit) and over-retention (holding expired I-9s that contain violations) increase risk.

Retention periods by document type:

• Form I-9: 3 years from the hire date OR 1 year after termination, whichever is later (note: for long-tenured employees, this can extend well beyond 3 years)
• LCA / Public Access File: 1 year after the last H-1B employment under the LCA, or 1 year after LCA expiration or withdrawal
• H-1B payroll records: 3 years from creation
• PERM (ETA 9089) and full audit file: 5 years from filing date, per 20 CFR 656.10(f)
• E-Verify records: Employers retain E-Verify case information alongside the corresponding I-9 and follow the I-9 retention schedule. The 10-year retention period under NARA Schedule N 1-566-08-7 applies to government records within the E-Verify system, not directly to employer files.

Documented destruction schedules help manage retention compliance. I-9s stored in a dedicated system, separate from general HR files, limit the scope of ICE inspection requests. Electronic storage must meet the integrity, quality assurance, indexing, and legibility requirements of 8 CFR 274a.2(e) through (i).

Anti-Discrimination Compliance in the I-9 Process

The DOJ Immigrant and Employee Rights Section (IER) enforces four prohibitions: citizenship status discrimination, national origin discrimination (for employers with 4 to 14 employees; EEOC handles 15+), unfair documentary practices (document abuse), and retaliation. Enterprise employers face the highest exposure on document abuse, meaning requesting more documents than required, demanding specific documents, or rejecting documents that reasonably appear genuine.

Key anti-discrimination rules in the I-9 process:

• Employees choose which acceptable documents to present; employers may not request a specific document (such as a Permanent Resident Card from LPRs or a passport from any employee)
• U.S. citizens and LPRs who presented a standard Permanent Resident Card are not subject to reverification when their documents expire
• Identical I-9 procedures apply to all employees regardless of citizenship status, national origin, or appearance
• E-Verify checks run for all new hires uniformly; no adverse action may be taken during the Tentative Nonconfirmation resolution period
