Dataset families
3
H1B, LCA, and PERM are the core data families used across the platform.
Data Sources
Official public datasets are the foundation.
All insights are derived from publicly available U.S. government datasets. WorkVisaInsights organizes those records into searchable employer, job, salary, location, and trend views.
Trust snapshot
Built for source transparency, clear boundaries, and fast research.
Primary source
U.S. Department of Labor
Additional source
USCIS where applicable
Use case
Transparent public-data research
Source statement
All insights are derived from publicly available U.S. government datasets. WorkVisaInsights normalizes and aggregates those disclosures for research, but users should verify critical decisions against the official source files.
Source type
Official
Records come from public government releases rather than private user submissions.
Data posture
Citeable
Pages expose source context so researchers and journalists can attribute carefully.

Field Context
How source fields become product context
The platform preserves the meaning of source fields while making them easier to navigate.
- Employer names
- Normalized for search and aggregation while preserving source-level context where possible.
- Roles and SOC codes
- Used to group related occupations, compare salaries, and build job intelligence pages.
- Locations
- Worksites and state/city fields power location and market comparison pages.
- Wages and salaries
- Reported wage fields are used for medians, ranges, and salary benchmark surfaces.
Public record basis
The platform does not create immigration outcomes; it indexes and summarizes public records.
Normalization layer
Names, locations, roles, wages, and dates are cleaned for better search and aggregation.
Clear limitations
Data may contain source-file omissions, amendments, duplicates, or publication delays.
