How this list is built

Gradlume combines public H-1B approval records with curated employer entries. Names may be grouped across legal entities. State coverage includes reported filing locations and curated office listings; industry groups combine public sector classifications with curated labels. Counts describe this directory’s coverage, rather than every US sponsor.

Approval figures describe petitions, not unique workers or job openings. Employers with incomplete or unmatched records can still appear here. Review the individual record before applying.
