Wholesale Trade vs Professional, Scientific & Technical Services

NAICS-sector comparison built from the H1B Report corpus. Filing volume, distinct sponsor count, sponsor concentration and dominant occupations.

Summary

Professional, Scientific & Technical Services (NAICS 54) and Wholesale Trade (NAICS 42) show starkly different H-1B sponsorship patterns. Professional Services leads dramatically with 5.36 million filings across 57,468 employers, while Wholesale Trade accounts for 118,161 filings from 7,818 employers—a 45-fold difference in filing volume.

Professional Services' heavy H-1B reliance reflects its composition: software development, engineering, consulting, and IT services firms that routinely sponsor temporary skilled workers. Wholesale Trade's minimal H-1B presence aligns with its business model, which typically relies on domestic labor and supply-chain logistics rather than specialty visa sponsorship.

By employer count, Professional Services also leads substantially, with 57,468 H-1B sponsors compared to 7,818 in Wholesale Trade. This gap underscores that H-1B sponsorship is concentrated in knowledge-intensive sectors rather than commodity-focused industries.
