The practice

Who they file for, what the jobs are and where the work sits, from the employer, occupation and worksite on their own applications.

What the jobs are

Software Developers

SOC 15-1252.00 · 361 filings, 25% of everything they file · 99.7% approved

How this is counted

These are the 6 occupations with the most filings, 593 of 1,456 cases between them. The occupation on a PERM is the SOC code on the form, which is the job as DOL classifies it rather than the job title on the offer. DOL still accepts two SOC vintages, so one job can appear twice under two codes; the code is printed for exactly that reason.

Where the jobs are

  • California 824
  • Massachusetts 121
  • Texas 109
  • New York 83
  • Colorado 30
  • Ohio 29
How this is counted

The worksite state on the application, which is where the job is and not where the company is headquartered. Volume by state across everyone is on the state map. These 6 states cover 1,196 of 1,456 filings.

Each bar counts firms at that value. More
Each bar counts firms at that value. Firms with fewer than 30 decided cases are left out of the population rather than plotted, because a rate over a handful of cases lands wherever the handful landed. The line marks this one. Approval rates pile up against 100%, so read the ties in the label rather than the position of the line.

Why no approval rate

A band is a slice of the volume ranking rather than a population picked for having enough decided cases, so a band rate would be solid at the top of the list and noise at the bottom, under one heading.

Where this sits in the ranking

Ranked 26 of 5,571 by volume: 25 filed at least as many cases, and 5,545 filed no more.

Notes on these numbers

What this rank counts, and what it doesn't

DOL prints the name that went on the form, so one firm can appear under several. The entry below start the same way and were not merged, because the difference between them is more than a mistyped letter. Some may be the same firm; some are a different one. Rank #26 counts this page's cases only.

250 filings sit on those pages rather than this one. The methodology has the rule that decides which spellings merge.

What these numbers don't say

5 notes
The wage is the job, not the payer
Their filings are led by Software Developers, 361 of 1,456. The median offered wage moves almost entirely with what roles their clients file. A software developer and a poultry cutter are different numbers wherever they are filed, so this figure is not plotted against the field and no percentile is given for it: that comparison would rank occupation mix and call it pay. Wages by occupation are on the wages page.
Nothing here is waiting
All 1,456 of the cases on this page carry a decision date, because every row in DOL's disclosure files does, so a case still in the queue is in none of these counts. The live tracker that does see pending cases records the employer on each one and not the firm, so a firm's current queue cannot be broken out at all. Where the queue stands overall is on the processing times page.
The approval rate barely separates firms
This firm is at 99.4%. Across every firm with enough decided cases to carry a rate the median is above 99%, and hundreds have no denials at all. Placing near the top of that axis mostly means being level with the rest of it.
None of this measures the advice
It measures filings that DOL approved or denied. Whether the case was worth filing, what it cost, and how the firm handled an audit aren’t in these files.
A median over 1,370 decided cases
DOL works one national queue, oldest first, whoever filed the case, so this says when the firm's cases were filed at least as much as anything about the firm. Where the queue stands today is on the processing times page.

The window these figures cover: DOL's PERM disclosure files for fiscal years 2024 to 2026, through the third quarter of 2026, 373,939 decided cases. Nothing pending is counted here. How each figure is built

Filings newer than DOL's last published file can't be attributed to this firm until DOL publishes them. The live list on the case search page carries them by employer.

Case data: DOL quarterly disclosure files (flag.dol.gov) · data through Jun 30, 2026 · quarterly

Employers and firms: Derived from DOL's disclosure files · data through Jun 30, 2026 · rebuilt with each quarterly load

LCA disclosures: DOL quarterly LCA disclosure files (www.dol.gov) · data through Jun 30, 2026 · quarterly

Wage determinations: DOL quarterly PW disclosure files (www.dol.gov) · data through Jun 30, 2026 · quarterly

What each source includes

Case data: Decided PERM cases only. A case still waiting isn't in here, so counts and durations describe finished cases.

Employers and firms: Employers, law firms and occupations ranked from decided cases only.

LCA disclosures: Certified and denied H-1B labor condition applications only, with the wage offered.

Wage determinations: Decided prevailing wage requests only, with the wage DOL determined. Pending requests are absent.
