- **USCIS Processing Times:** Daily snapshots from [jzebedee/uscis](https://github.com/jzebedee/uscis) GitHub releases (primary), supplemented by direct USCIS API queries
- **Visa Bulletin:** Monthly State Department visa bulletin publications
- **DOL PERM:** Department of Labor FLAG system processing queue data

## Methodology

Processing time estimates are published by USCIS as ranges (lower and upper bounds in months). Each row represents one form–office–subtype–date combination. Values are normalized to months. Snapshots are captured daily when USCIS publishes new data (typically every 2–4 weeks).
