The dataset generation failed because of a cast error
Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 1 new columns ({'fiscal_year'}) and 10 missing columns ({'first_fy', 'cert_withdrawn_pct', 'top_soc_title', 'employer_slug', 'employer_state', 'denied_pct', 'top_soc_code', 'withdrawn_pct', 'last_fy', 'employer_name'}).

This happened while the csv dataset builder was generating data using

H-1B / LCA Open Data — aggregate tables (FY2010–FY2026)

Aggregate statistics on 9,331,644 US Labor Condition Applications (LCAs) — the wage-and-worksite filing every employer must submit to the Department of Labor before sponsoring an H-1B, H-1B1, or E-3 worker. Covers 126,466 employers and 782 occupations across fiscal years 2010–2026.

This is a mirror. The canonical home of this dataset — always the newest release, with the data dictionary and license — is https://h1b.report/open-data. Mirrors are refreshed at least one quarterly release behind the canonical page. The same data is also served interactively (charts, rankings, per-employer analytics) at https://h1b.report.

What's here

File Rows Grain
national_by_year.csv 17 fiscal year
occupation_by_year.csv 4,477 SOC × fiscal year
occupation_by_state.csv 6,578 SOC × worksite state
occupation_wage_by_level.csv 1,132 SOC × prevailing-wage level
state_by_year.csv 931 state × fiscal year
sector_by_year.csv 425 NAICS-2 sector × fiscal year
employers_summary.csv 18,927 canonical employer
soc_coverage_by_year.csv 17 fiscal year (coverage diagnostic)

sample_occupation_by_state.csv is a 100-row preview. Column-level definitions are in data_dictionary.md.

How it's cleaned

Raw OFLC files are inconsistent across years — the schema changed in FY2020 (the FLAG release), employer names are free text, and wages are quoted hourly, weekly, bi-weekly, monthly, or yearly. This release is derived from a normalised corpus:

  • Canonical employers. Name variants ("IBM Corp.", "I.B.M. Corporation", "International Business Machines") are resolved to a single canonical employer, so an employer's filings aren't scattered across spellings. Aggregates key on the canonical employer; the underlying name-variant mapping is not published.
  • SOC occupation codes are normalised to a single taxonomy, with job titles matched against the BLS Direct Match Title File and a classifier for the rest.
  • Annualised wages. WAGE_RATE_OF_PAY_FROM is converted to annual USD (hourly × 2080, weekly × 52, bi-weekly × 26, monthly × 12).

Caveats — please read before citing

  • An LCA is not a visa. It is a prerequisite filing. It is not an H-1B petition, not an approval, and not a hire. One filing can cover multiple positions, and many filings never become petitions. Filing counts are not visa counts.
  • Wages are offered wages, not take-home pay. WAGE_RATE_OF_PAY_FROM is the bottom of the offered range on the filing. It excludes bonus and equity, and it is not verified against what was actually paid.
  • FY2026 is partially reported. It currently holds 210,387 filings against 596,552 in FY2025 (65% lower), which reflects reporting lag, not a real drop. DOL publishes quarterly, so the most recent fiscal year is the least complete and its totals will rise in later releases. It is left uncorrected here — do not read it as a real decline.
  • A small share of filings carry no occupation code. 4.7% of filings (443,000) carry no SOC code. This is a flat background rate, not a gap in particular years: per-year coverage runs 94.5%-95.9%, so years remain comparable with each other. The three occupation_* files only include filings that carry a SOC code. The national, state, and sector files are unaffected — they count every filing. Per-year coverage is published in soc_coverage_by_year.csv.
  • Small cells are suppressed. Any row backed by fewer than 25 filings is omitted, so columns do not sum exactly to national totals.
  • Wage outliers are excluded. Only wages between $20,000 and $1,000,000 annualised are counted, dropping data-entry errors.
  • Percentages are of all filings for that entity, including still-pending ones.
