U.S. Immigration Data · REST API
The Visa Bulletin, USCIS, and PERM timelines, as clean structured data.
Public immigration data is scattered across PDFs and form-by-form government portals. VisaVigil parses, archives, and serves it — visa bulletin history, live USCIS processing times, DOL PERM queues, employer-level sponsorship and wage data, and calculations no one else offers as an API: the priority-date estimate, the I-485 filing check and CSPA age.
What you can call
One key for every endpoint.
Every response is JSON, documented in an interactive OpenAPI spec, and served over authenticated HTTPS.
Visa Bulletin
Current cutoffs and the full monthly history since 2015 for every category and country — plus computed movement stats, like how many days a queue advanced over the past year. It also carries which chart USCIS accepts for I-485 filing each month, at /v1/visa-bulletin/aos-filing-chart.
USCIS Processing Times
Current processing ranges for 40+ forms across every service center and field office, snapshotted daily so you can show the trend, not just today's number.
PERM Processing Times
Where DOL's ETA 9089 queues stand — analyst review, audit, reconsideration — with six years of monthly history, movement rates, and an estimate of when the queue reaches your filing month. The history is what shows how far the average analyst-review time has moved since 2020.
Priority-Date Estimator
A transparent estimate of when a priority date becomes current, computed from real movement rates — with honest result types when a category is stalled or unavailable.
I-485 Filing Check
Whether an adjustment-of-status application may be filed this month for a priority date, by USCIS's own monthly choice of chart for family and employment cases. The designation history runs back to October 2015 at /v1/visa-bulletin/aos-filing-chart.
CSPA Age Calculator
Child Status Protection Act age, resolving visa availability straight from the bulletin history.
Employer Sponsorship Data
Search 480,000+ sponsoring employers. Per-company H-1B approvals and denials since 2009, LCA filings with real offered wages, PERM history, and wage percentiles by job, state, and year — 6.3 million case records from USCIS and DOL disclosures.

Why build on it
6.3 million records. One reliable layer over data that fights developers.
Parsed, not scraped by you
The State Department publishes the bulletin as HTML and PDF; USCIS hides processing times behind a form-by-form portal. We do that work once so you never write a parser.
A daily archive that compounds
Every day we snapshot USCIS processing times and DOL's PERM queues, building a trend history you can chart — the kind of longitudinal view a single lookup can never give.
Calculations, not just data
The estimator and CSPA endpoints answer the questions people actually ask — "when will I be current," "will my child age out" — computed on top of the raw history.
Honest by design
Every derived answer is clearly labeled informational, carries its policy date, and flags uncertainty. Built by immigration attorneys, for products that can't afford to mislead.
