Industry comparison

Administrative & Support Services 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 Administrative & Support Services (NAICS 56) represent distinct H-1B sponsorship patterns. Professional Services leads overwhelmingly with 5,362,182 filings across 57,468 employers, while Administrative & Support Services filed 110,482 times across 3,695 employers—a roughly 49-to-1 ratio in filings.

Professional Services attracts far more H-1B sponsorship because it encompasses high-skill roles in IT, engineering, R&D, and consulting where visa workers fill specialized, higher-wage positions. Administrative & Support Services, though smaller in H-1B volume, still sponsors visa workers for roles in office administration, staffing, and facility management across a more fragmented employer base.

The difference in employer count (57K vs 3.7K) reflects the scale and consolidation of tech and professional firms versus the distributed nature of administrative services.
