H-1B LCA Filers With the Highest DOL Certification Rates

PlainVisa ranks large H-1B LCA filers (500+ LCA filings) by DOL LCA certification rate from the live disclosure database.

Research question

Among employers that file in volume (500 or more H-1B Labor Condition Applications), which achieve the highest DOL certification rates, and does filing at scale trade off against a clean certification record?

Why the certification rate matters

A Labor Condition Application (LCA) is filed with the U.S. Department of Labor before a separate H-1B petition can be filed with USCIS. This page reports the certification-status fields in the DOL extract. The rate is descriptive: it does not identify why a filing had a particular disposition or establish an employer's compliance, employment practices, or USCIS outcomes.

Certification is not the same as visa approval. The LCA is the labor-condition step that precedes a separate I-129 petition; USCIS then decides that petition. A 100% certification rate tells you an employer has DOL-certified wage attestations, not that any worker ultimately received a visa. We restrict this ranking to employers with at least 500 LCA filings so the rate reflects a sustained filing pattern rather than the statistical noise of a handful of applications.

Methodology

We compute the certification rate as DOL-certified LCA filings divided by total LCA filings for every employer with 500 or more filings, then rank by that rate (ties broken by volume). The headline ranking and the reference-rate aggregate are computed on exactly the same filtered population. Every figure on this page reflects the current data; none is hardcoded, and the numbers refresh whenever the underlying DOL LCA dataset is updated.

The 500-LCA-filing floor is a deliberate editorial choice. Certification rate is a ratio, and ratios are unstable for small denominators: an employer filer with four applications and one returned shows a 75% rate that says little about the underlying DOL record. The threshold reduces small-denominator volatility; it does not establish compliance or documentation quality.

Records with a null certified-LCA filing count are excluded rather than treated as zero, because a missing value is not the same as a denial. Where the source revises a count in a later vintage, the revised figure flows through automatically with no change to this page's code. The methodology page documents the full data-update process, source vintage, and field definitions.

Findings

Does scale cost cleanliness?

The chart compares DOL certification-status rates among high-volume LCA filers. It can show whether a rate differs from the filtered population-wide rate of 98.8%, but the extract does not establish the cause of that difference.

What a near-perfect rate signals

A near-perfect rate means the DOL extract records a high certified share for the selected source window. It is not a rating of an employer, a prediction of sponsorship, or evidence about a worker's eventual immigration outcome.

How to read the leaderboard responsibly

The denominator matters: two employers can have the same percentage with very different filing totals. Read the rate, certified count, and total filing count together as a description of the DOL record, not a judgment about an employer or a worker-facing recommendation.

What this analysis cannot tell us

Certification is the DOL labor-condition step, not a USCIS visa decision. A high certification rate does not establish that an I-129 petition was filed, approved, or used for employment. Rates are computed on certified versus total LCA filings and can include withdrawn or returned applications in the denominator. The 500-LCA-filing floor excludes smaller employer filers whose rates would be statistically noisy. Certified wages are attested wages, not necessarily wages ultimately paid. Comparisons across employers should account for differences in occupation mix and worksite geography.
