By state

FAQs

How are the firms ranked?
By how many cases DOL decided with the firm named on them, in one fiscal year (October to September). PERM counts every decision, certified, denied or withdrawn; H-1B counts certified LCAs for the H-1B class. Each firm's spellings in DOL's files count as one firm.
Is a busier firm a better firm?
No. The rankings show how much each firm filed, how its PERM cases ended and how long they took. They say nothing about service, price or fit, and a smaller firm may suit a case better. Nothing here is a rating.
Why does a state's ranking differ from the country's?
A state's ranking counts only the cases for jobs in that state, so a national firm ranks by the work it files there. A firm's own page shows all of its filings.
Why are individual attorneys not listed?
DOL's files name the law firm, and this site names firms only. Each firm's page lists its filings, employers and outcomes.
How these are counted

PERM counts every case DOL decided in the fiscal year with the firm named on it: certified, denied or withdrawn. The certified share leaves withdrawals out, because a withdrawal isn't a decision on the case. Days to certify run from filing to certification, shown when a firm has ten or more certifications. A case counts in the state of its job; where DOL's older files print no worksite, the employer's state.

H-1B counts certified LCAs for the H-1B class only (H-1B1 and E-3 left out), in the state of the job. Positions are the workers each LCA covers. An LCA comes before the petition, and not every LCA becomes one.

"The year before" is the firm's rank among every firm with filings there that year. Cases that name no law firm were filed by the employer itself: they're in the split above and ranked nowhere.

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