What These Numbers Tell You
Buffalo Grove is a moderate H-1B market by national standards — #300 of 910 metros tracked. Volume of 22 filings sits in the upper half of U.S. cities, but most filings are concentrated among a smaller pool of large employers rather than spread broadly across the local economy.
Average offered wage in Buffalo Grove is $132,762 — well above the U.S. national average for full-time work. Most H-1B-sponsored roles in this metro are mid- to senior-level professional positions; the figure is heavily weighted by tech, healthcare practitioner, and engineering occupations.
Buffalo Grove's certification rate of 100.0% is at or above the national norm. The U.S. Department of Labor certifies LCAs that meet wage and notice requirements, so high rates typically reflect employers that file complete applications with prevailing wages set at or above the required level. Note that LCA certification by DOL is only the first step — the H-1B petition is then adjudicated separately by USCIS.
