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

Summary

Administrative & Support Services (NAICS 56) and Manufacturing (NAICS 33, metal/machinery/electronics) represent different scales of H-1B sponsorship in the U.S. economy.

Manufacturing dominates H-1B activity, filing 314,824 petitions across 7,385 employers. This reflects the sector's large workforce and reliance on specialized technical roles in production, engineering, and quality assurance. Administrative & Support Services filed 43,926 petitions across 2,019 employers—a significantly smaller volume despite serving as a backbone for business operations across all industries.

The employer-to-filing ratio differs notably: Manufacturing averages 42.6 filings per employer, while Administrative & Support Services averages 21.8. This suggests Manufacturing sponsors more H-1B workers per company, likely due to the skill intensity and scale of technical production roles compared to administrative positions.
