Sponsoring an H-1B worker doesn’t end when the I-797 approval notice arrives in the mail. In reality, that is when your regulatory obligations actually begin.
Over the past few years, federal oversight of the H-1B program has shifted dramatically. The Department of Labor (DOL) and U.S. Citizenship and Immigration Services (USCIS) no longer rely solely on formal complaints to open an investigation. Through targeted initiatives and increased funding for Fraud Detection and National Security (FDNS) officers, government agencies are proactively auditing companies of all sizes.
Most of the time, when a company gets flagged, it isn’t because they were trying to cheat the system. It’s usually because someone in HR or management missed a basic administrative detail.
Here is what actually triggers these investigations, what happens during a government visit, and how to keep your company compliant.
What Triggers an H-1B Audit?
Federal investigators rarely pick companies out of a hat. Most H-1B audits stem from specific operational red flags that pop up during routine data checks or site visits.
The most common compliance triggers include:
- Unlawful Benching: If a client project ends or business slows down, you cannot put an H-1B worker on unpaid leave. Under federal law, employers must pay sponsored employees their full required wage continuously, regardless of whether there is active work available.
- Unreported Job Changes: Moving an employee to a new office, a client site, or a remote home office in a different metropolitan area without filing a new Labor Condition Application (LCA) and amended petition is an immediate red flag.
- Incomplete Public Access Files: Missing wage explanations, outdated prevailing wage data, or missing proof of LCA postings in your Public Access File (PAF) can cause an investigator to expand a routine check into a full audit.
- Wage Discrepancies: Paying less than the salary stated on the LCA, or making unauthorized payroll deductions for visa processing fees, violates Department of Labor rules.
What Actually Happens During an Unannounced FDNS Site Visit?
USCIS site visits are unannounced, brief, and very specific. An FDNS officer will typically walk into your main office or client site, present their credentials, and ask to speak with HR and the H-1B worker.
During the visit, the officer is trying to verify three main things:
- Physical Existence: Does your company actually operate at the address listed on the petition?
- Job Alignment: Is the employee physically sitting at their desk performing the exact duties described in the filing?
- Financial Compliance: Is the employee being paid the salary listed on the certified LCA?
The officer will interview the employee directly, ask about their daily duties and pay rate, and request to see their recent pay stubs or the company’s Public Access File.
How Employers Can Stay Fully Compliant
Staying out of trouble isn’t about hiding from the government, it’s about building consistent internal processes. Here is how you can keep your company audit-ready at all times.
- Build Your Public Access File (PAF) Immediately
Federal rules require employers to create a complete Public Access File within one working day of filing the LCA with the Department of Labor. Don’t wait until USCIS approves the petition.
Make sure every PAF includes:
- A copy of the certified LCA.
- Proof of the prevailing wage and the source used to find it.
- A brief memo explaining how the company set the employee’s actual wage.
- Proof that the LCA notice was posted at the worksite for 10 consecutive business days (or sent digitally to staff).
- A summary of benefits offered to all employees in similar roles.
- Pay Continuous Wages (Or Execute a Proper Termination)
If work dries up, you must continue paying the worker their full wage. The only legal way to stop paying an H-1B employee is through a bona fide termination. To execute this legally, you must notify USCIS that the employment has ended, update your payroll records, and offer to pay for the employee’s reasonable cost of return transportation to their home country.
- File Amendments Before Making Changes
Always consult your immigration counsel before changing an H-1B employee’s job title, salary, work duties, or physical work location. You must file an amended H-1B petition with USCIS before the employee starts working under the new terms.
- Train Your Front Desk and HR Staff
Because site visits happen without warning, frontline employees are often caught off guard. Establish a clear protocol:
- Receptionists should know who to contact immediately when a government official arrives.
- Staff should always ask for the officer’s credentials and business card.
- HR should answer questions directly and factually without guessing or volunteering unverified information.
- Conduct Annual Internal Audits
Set a calendar reminder once or twice a year to review your active H-1B files. Check that every worker is physically located where their LCA says they are, confirm that payroll matches the required prevailing wages, and verify that all PAFs are complete and accessible.
Staying Proactive with H-1B Compliance
At the end, federal immigration enforcement isn’t about setting traps for well-meaning businesses, it’s about ensuring that the terms promised on paper match what is actually happening in the office. Operating under the assumption that an FDNS inspection or a DOL document review will happen eventually is the safest mindset an HR team or business owner can have.
By building standard operating procedures around your Public Access Files, staying on top of work location changes, and keeping your frontline staff prepared, you remove the chaos from compliance.
