The industry is the NAICS code the employer entered on the form. DOL publishes the code alone; the title is the Census Bureau's, and a code Census never defined takes its parent group's title.
Case data: DOL quarterly disclosure files (flag.dol.gov) · data through Jun 30, 2026 · quarterly Decided PERM cases only. A case still waiting is not in here, so counts and durations describe finished cases, not the queue.
