USCIS Onsite Inspections: Practical Guidance for H-1B Employers in 2026
If you have filed or are currently sponsoring an H-1B worker, an unannounced visit from a USCIS Fraud Detection and National Security (“FDNS”) officer is no longer a remote possibility, it is common, routine occurrence. Employers who are unprepared risk at a minimum revocation of approved petitions, and at worst debarment from the program, and/or civil or criminal liability. The following practical guidance tells you exactly what to expect, what to preserve, and how to respond.
What is an FDNS Site Visit?
USCIS’s Fraud Detection and National Security Directorate conducts administrative site inspections or commonly called “site visits” to verify most routinely that the facts and representations made in an H-1B petition are accurate. FDNS officers are not required to give advance notice before arriving at a worksite. Their mandate covers both pre-approval verification and post-approval compliance monitoring, meaning employers can be visited at any stage of the H-1B lifecycle.
Since the 2017 Buy American and Hire American Executive Order and accelerated under enforcement guidance renewed through 2025 and into 2026, FDNS has significantly expanded its inspection capacity. Employers at third-party client sites, IT staffing firms, and professional services companies should treat site visits as a routine compliance events, not an anomaly.
Who Gets Audited & What Triggers a Site Visit?
USCIS does not publicly disclose every factor used to select employers for FDNS inspections. However, in practice, certain filing patterns and operational structures are more likely to trigger scrutiny.
Common risk factors include:
- Third-party client placements
- IT consulting and staffing company models
- Newly formed businesses sponsoring H-1B workers
- Remote or hybrid work arrangements not reflected in the petition
- Significant discrepancies between LCAs, payroll records, and actual work locations Multiple H-1B filings from the same employer
- Prior RFEs, NOIDs, or petition revocations
- Anonymous complaints or whistleblower reports
- Social media allegations or online fraud accusations
- Rapid changes in business structure or employee assignments after approval
USCIS may also conduct purely random compliance checks. Even fully compliant employers with no adverse history can receive site visits.
Employers should understand that FDNS inspections are not limited to fraud investigations. Many are administrative verification exercises intended to confirm that the worker is employed under the same terms represented in the approved petition.
Step-by-Step Site Visit Timeline
FDNS site visits generally follow a predictable sequence. Understanding each phase allows your team to respond lawfully and professionally without inadvertently volunteering information that creates exposure.
Phase | What Happens |
|---|---|
| Phase 1 – Arrival | Unannounced Appearance at the Worksite A plainclothes FDNS officer arrives at the employer’s place of business or the third-party client site listed in the petition. The officer presents government credentials. Your front desk or receptionist should politely verify credentials, take a photograph of the badge if possible, and immediately notify the designated HR or legal contact. Do not permit access to any office space or employee until your point of contact arrives. |
| Phase 2 – Initial Contact | Identification of Purpose & Scope The officer will identify the H-1B worker or workers at issue and state the general purpose of the visit. They may indicate whether this is a targeted visit or a random administrative check. Request a business card and note the time of arrival. Politely inform the officer that you will cooperate fully and need a brief moment to contact your legal counsel or HR lead. |
| Phase 3 – Interview | Employer Representative & Employee Interview The officer will typically seek to interview the H-1B beneficiary and the designated employer representative, such as a direct supervisor or HR manager. Questions generally focus on job duties, work location, salary, reporting structure, and whether employment conditions match the approved LCA and I-129 petition. Employees should answer truthfully and concisely. |
| Phase 4 – Records Review | Public Access File & Supporting Records The FDNS officer may request access to the Public Access File (PAF), payroll records, W-2s, timesheets, project assignments, organizational charts, and other supporting documentation. Employers should maintain complete and organized records for every sponsored worker. |
| Phase 5 – Observation | Worksite Walk-Through Officers may request a physical tour of the workspace to verify that the H-1B worker is present and performing the duties described in the petition. Employers may designate an escort. Refusing reasonable access may be noted and reported. |
An Employer should designate a FDNS single point of contact; ideally an HR manager or in-house counsel, before a visit ever occurs and provide front desk staff training in the event of an FDNS Site Visit. Employees who panic or over-explain during an unannounced visit create avoidable problems. A calm, cooperative, and structured response is always your best posture.
What Records Must You Make Available?
Federal regulations under 20 C.F.R. Part 655 and 8 C.F.R. § 214.2(h) impose specific document retention obligations on H-1B employers. Failing to maintain required records is itself a violation, independent of whether any underlying non-compliance occurred.
Document Category |
Retention Period |
Notes |
|---|---|---|
| Public Access File (PAF) | 1 Year After Employment Ends | Must include the Labor Condition Application (LCA), wage rate documentation, and prevailing wage source. |
| Payroll Records | 3 Years | Must confirm that actual wages paid equal to or exceed the wage rate listed in the LCA. |
| Form I-129 Petition & Supporting Exhibits | 3 Years from Filing | Retain copies of all approved, pending, withdrawn, and denied petitions. |
Best practice is to maintain all H-1B records for a minimum of three years after the termination of employment, even where regulations specify a shorter period. In the event of litigation or a DOL investigation, contemporaneous records are your most powerful defense.
What Information & Documents is an FDNS Officer Likely to Request?
Category | Documents / Records |
|---|---|
| Employee Records |
|
| Immigration Records |
|
| Employer Business Records |
|
| Third-Party Placement (if applicable) |
|
You are not required to produce documents on the spot that are not in your possession at the worksite. You may respectfully inform the officer that you will supply the documents in writing within the requested timeframe. Never produce documents you have not reviewed. Producing incomplete or inconsistent records is more harmful than a brief, good-faith delay.
Social Media Investigations & Public Fraud Allegations
TikTok Users Exposing #H-1B Visa Fraud
In 2026, a new and troubling development is the proliferation of private individuals, who are approaching employers and H-1B workers on camera, often for social media distribution in an effort to expose alleged H-1B visa fraud, particularly focusing on “phony businesses” or “ghost offices” in Texas. These videos often designed to provoke, embarrass, or manufacture evidence of “fraud,” have generated FDNS referrals and caused very real harm to employers and sponsored workers. These actors typically appear unannounced at worksites, sometimes posing as delivery personnel or building visitors to gain access. They may film H-1B workers at their desks, in common areas, or in parking lots, often demanding to know their visa status, job duties, or salary. Videos are commonly posted to platforms like TikTok with inflammatory titles alleging H-1B fraud or “visa abuse”.
These so-called TikTok Activists have no legal standing in USCIS proceedings. However, their content can trigger formal complaints to FDNS, attract media attention, and create reputational harm that is difficult to reverse, particularly in Texas where Attorney General Ken Paxton has announced sweeping investigations into H-1B visa abuse. Therefore, the practical answer is speed: a firm, lawful, and documented response that demonstrates your compliance posture is more valuable than any public rebuttal.
Employer Action Required
Train your staff now. Employees, including front desk, reception, and security personnel, should be instructed that:
- No one without valid government credentials is entitled to record, question, or photograph employees on company property.
- Staff should not engage in arguments. If information is requested, only the Public Access File (PAF) should be provided.
- The individual should be politely escorted off the premises, and management should be notified immediately.
If trespassing has occurred, file a police report and notify immigration counsel immediately. Such incidents can trigger USCIS inquiries that may require a prompt and proactive response.
What Consequences May Follow an FDNS Site Visit?
FDNS site visits that reveal discrepancies between the petition and the actual employment relationship can trigger a number of consequences. The severity depends on whether the violation is technical like a minor inconsistency in recordkeeping or substantive like the worker is performing completely different duties, is benched without pay, or is placed at an unlisted location.
1. Notice of Intent to Revoke (NOIR). USCIS may issue a NOIR requiring the employer to demonstrate why the approved H-1B petition should not be revoked. The employer typically has 30 days to respond. A revocation terminates the beneficiary’s H-1B status and triggers an immediate loss of work authorization.
2. Request for Evidence (RFE). Where USCIS needs additional documentation to determine compliance, it will issue an RFE. RFEs during the post-approval period are substantively different from pre-approval RFEs — they carry greater weight and, if inadequately answered, frequently lead to revocation.
3. LCA Violations & DOL Back Wage Orders. If USCIS finds the worker was paid below the prevailing wage rate specified in the LCA or was placed in an unpaid “bench” status, the case is referred to the Department of Labor’s Wage and Hour Division. Civil monetary penalties range up to $10,000 per violation, with additional back wage liability.
4. Debarment from H-1B Program. Willful violations including knowing misrepresentation in the petition, unauthorized substitution of workers, or pattern and practice of non-compliance can result in debarment from filing future H-1B petitions for one to three years or permanently. Debarment effectively ends a business’s ability to sponsor foreign workers.
5. Criminal Referral. Knowing and willful fraud in connection with an immigration petition is a federal criminal offense under 18 U.S.C. § 1546. Employers who fabricate employment relationships, forge supporting documents, or knowingly misrepresent job duties face potential prosecution. ICE Homeland Security Investigations (HSI) may also open parallel investigations.
6. Beneficiary Consequences. A revoked H-1B status may render the sponsored worker immediately out of status, triggering accrual of unlawful presence. Departure from the U.S. may trigger a three- or ten-year bar to reentry, depending on the period of unlawful presence accumulated. The human cost of employer non-compliance falls, in the first instance, on the worker.
Frequently Asked Questions (FAQ)
Q1- How long after H-1B approval can a USCIS site visit occur?
A site visit can occur at virtually any time during the H-1B lifecycle. USCIS may conduct inspections before approval, shortly after approval, during extension filings, or years later while the petition remains active. There is no statutory deadline limiting when FDNS may initiate a visit.
Q2- Can USCIS conduct a site visit at a third-party client location?
Yes. USCIS routinely conducts site visits at third-party client locations listed in the H-1B petition or supporting documents. This is especially common in IT consulting, staffing, and project-based industries. Employers should ensure end clients are aware of the placement and prepared to verify the worker’s role and assignment.
Q3- What should employers do if business operations or employee work locations have changed since the H-1B petition was filed?
Employers should immediately evaluate whether the change requires filing an amended H-1B petition. Material changes including new work locations outside the original metropolitan statistical area (MSA), substantial changes in job duties, salary structure, remote work arrangements, or client placements may require updated LCA postings and amended filings.
Failing to update USCIS regarding material changes is one of the most common compliance issues identified during FDNS inspections.
Prepare Before the Knock at the Door
The time to build your compliance infrastructure is not the morning an FDNS officer appears in your lobby. H-1B employers should conduct internal audits of their PAFs, review their payroll, confirm actual work assignments match approved petitions, and train all client-facing and HR personnel on proper site visit protocols. Consider a pre-visit compliance review with immigration counsel, it is far less expensive than defending a revocation proceeding.
