The University of Iowa's H-1B petition approval rate

Not the LCA certification rate every site quotes (the Department of Labor certifies ~99% of LCAs) — this is the USCIS first-decision approval rate on the actual H-1B petitions, where denials are real. Across 539 new (initial) petitions, FY2019–FY2024.

Initial approval rate
98.5%
new petitions (FY2019–FY2024)
Initial approvals
531
of 539 decided
Overall approval rate
97.3%
incl. continuing (renewals)

Continuing (renewal) petitions approve at near-100% for almost every employer, so the initial rate is the meaningful signal. Counts cover FY2019–FY2024. Source: USCIS H-1B Employer Data Hub.
