H1B, LCA & Visa Compliance for Staffing Firms

For a corp-to-corp staffing firm, H1B compliance comes down to three obligations done consistently: pay the LCA required wage (including during bench time), base that wage on the end-client work location, and keep every filing and authorization document current. Get those right and you avoid the violations that produce back-wage liability, penalties, and in serious cases debarment from the H1B program. This guide explains each, plus the visa types and dates a staffing firm has to track.

Visa types a staffing firm has to track

Every bench consultant has a work-authorization status, and the firm's obligations differ by type. These are the categories that show up most in C2C staffing:

The LCA and the prevailing wage

The labor condition application (LCA) is the foundation of H1B compliance. By filing it, the employer attests to several conditions — most importantly, that it will pay the H1B worker at least the higher of the actual wage paid to similar workers or the prevailing wage for the occupation in the area of intended employment.

For staffing firms, the critical word is location. The prevailing wage is tied to the area of intended employment — the end-client worksite where the consultant actually works — not your firm's headquarters. Because C2C consultants are placed at client sites across the country, a single boilerplate wage tied to your office understates the required wage and creates back-wage exposure. When a consultant moves to a new worksite outside the original area, a new or amended LCA — and sometimes an amended petition — may be required.

Paying the required wage on the bench

This is the most expensive mistake in C2C staffing. An H1B worker in nonproductive status — benched, between projects, or waiting on a placement for reasons related to the employer — must still be paid the required wage on the LCA. There is no "we'll pay them when they're billing" exception for employer-driven downtime. The Department of Labor can order back wages for the entire unpaid period, add civil penalties, and in willful or repeated cases pursue debarment. Treat benched H1B consultants as a wage obligation from day one, and factor that cost into your markup.

Form I-129 and the 2025 overhaul

Form I-129 is the petition USCIS uses to classify a nonimmigrant worker, including H1B. USCIS overhauled the form effective January 17, 2025. Petitions submitted on an outdated edition are rejected — there is no grace period for using a retired version. A rejected I-129 costs a filing window and can delay or cost a placement, so confirm you are filing on the current edition every time.

The public access file

For every certified LCA, an H1B employer must maintain a public access file containing the LCA, the wage rate, the prevailing wage determination, and supporting documentation — and make it available within one working day of filing. Missing or incomplete public access files are a frequent finding in DOL investigations and carry penalties independent of whether wages were actually underpaid. The file is a low-effort obligation that becomes a high-cost finding when ignored.

Tracking expiry dates

Work authorization is not permanent. OPT, STEM-OPT, EAD cards, and TN status all carry hard expiry dates, and a consultant whose authorization lapses cannot legally work. The failure mode is always the same: the date lived in someone's memory or an unchecked spreadsheet, and a billing consultant suddenly fell out of authorization. Every authorization date needs an owner and an alert well before it expires — losing a consultant to a lapsed EAD is entirely avoidable.

Building compliance into operations

Every obligation above shares one root cause when it fails: compliance data scattered across spreadsheets, email, and individual memory. The structural fix is a single system of record that tracks each consultant's visa type, authorization expiry, LCA wage, worksite, and filing edition, and that alerts you before a deadline becomes a violation. When compliance lives in the same system as the pipeline, a firm can answer "is this consultant clean?" instantly — which protects the firm and wins placements over competitors who have to go check.
