About ImmigrationTimes.org

Who We Are

ImmigrationTimes.org has been collecting USCIS processing time data daily since March 2022, building one of the most comprehensive historical archives available. Our automated data pipelines gather processing time estimates from official government sources — including USCIS, the Department of Labor, and the State Department — and present them with historical trends, service center comparisons, and professional citation tools.

Our goal is to serve the immigration community: attorneys advising clients, applicants tracking their cases, university international student offices supporting students and scholars, and researchers and journalists studying immigration policy.

Independence & Transparency

ImmigrationTimes.org is editorially independent and accepts no advertising or sponsored content. All our data, tools, and citation features are free to use. Our historical dataset — over 39,426 data points spanning 4+ years — is the largest publicly accessible archive of USCIS processing time estimates. We believe immigration data should be a public good, not a product.

Data Sources

ImmigrationTimes.org aggregates processing time data from official U.S. government sources. Our primary data source is the USCIS Processing Times page, which publishes estimated processing time ranges for each immigration form at each service center.

Historical data is compiled from daily USCIS processing time snapshots collected since March 2022, providing over four years of continuous coverage. All data is cross-validated against direct USCIS API queries to ensure accuracy.

Dataset Overview

Coverage: Mar 21, 2022 to Apr 22, 2026.

Update Frequency

Data is updated automatically every day via an automated pipeline that:

1. Checks for new USCIS processing time releases
2. Downloads and validates new data
3. Merges into our historical database
4. Regenerates all site pages with current data
5. Detects changes and sends alerts to subscribers

USCIS typically updates processing times on their website approximately once per month per form, though the schedule varies. We check daily to capture updates as soon as they are published.

How Processing Times Are Calculated

USCIS processing times represent the time it takes to process a case from the date the case was received to the date the case was completed. USCIS publishes a range (minimum to maximum) for each form at each service center, based on 80% of adjudicated cases.

On ImmigrationTimes.org, processing times displayed at the form level are averages across all service centers that process that form. Individual service center times are shown in the comparison table on each form page. Status indicators (Fast, Normal, Slow, Very Slow) are based on percentile thresholds computed from historical data for each form.

Data Accuracy

We take data accuracy seriously. Every number on this site is verifiable against USCIS official data. Our pipeline includes:

• Automated validation on every data import
• Cross-referencing between multiple data sources
• Row count verification (alerts on unexpected decreases)
• Null/zero filtering to prevent display of invalid data

Citation Policy

All data on ImmigrationTimes.org is free to cite with attribution. We provide citation tools on every page — formatted text, embeddable charts, downloadable PNGs, and a JSON API.
