H1B Sponsor Checker: sources, changelog, reviews
Where the numbers come from
| What the panel shows | Source | Data through |
|---|---|---|
| H-1B approvals and denials by employer, FY2024–FY2026 | USCIS H-1B Employer Data Hub | 2026-09-30 (end of FY2026) |
| Certified LCAs and filed wages (median and range for similar titles) | U.S. Department of Labor, OFLC LCA disclosure data (FY2024 Q1 – FY2026 Q3) | 2026-06-30 (latest quarter DOL had released when we built the data) |
| Employer records in the bundled data: 117,330 (name variants grouped) | Counted by us from the two files above (extension file data/meta.json) | Built 2026-10-29 |
| "No sponsorship" note on a job page | That job page's own text, read on your computer | Whenever you open the page |
USCIS counts first decisions for beneficiaries. LCAs are wage filings, not petitions, so an LCA doesn't mean anyone got a visa. We match employer names automatically, and the match can be wrong. Use "Wrong company?" in the panel or email us. Past filings show what an employer did before. They aren't a promise to sponsor you, and none of this is legal advice. We're not affiliated with USCIS or the Department of Labor.
Why we built this
If you're on F-1/OPT or an H-1B, a job post rarely tells you whether the employer has sponsored anyone before, so you end up checking government files by hand for each job. The data is public, but it's spread across two agencies and lists employers under legal names that often don't match the name on the job board. We built a small panel that brings both records onto the job page you're already reading. It runs on your computer, with no account and no tracking. We're a small studio. Report a problem to media@autoquantix.com and we'll reply.
Changelog
| Version | Date | What changed |
|---|---|---|
| 0.1.7 | Chrome Web Store: updated Oct 30, 2026 · Firefox Add-ons: Nov 1, 2026 | The footnote now gives each data source's exact date range. The "No match found" message names the date ranges it searched. The short description mentions Resume Match. No data or permission changes. |
| 0.1.6 | Built Oct 29, 2026 | Security cleanup: the panel and popup are built from DOM nodes instead of HTML strings (fixes the Firefox reviewer warnings). No feature changes. |
| 0.1.5 | Firefox Add-ons: Oct 29, 2026 | USCIS FY2026 full fiscal year (data as of 2026-09-30). Fixed a bug where some employers showed the wrong filer or 0 approvals because of ID collisions. Display names now use each employer's most common spelling. |
| 0.1.4 | Built Oct 27, 2026 | Resume Match: paste your resume once (it's stored only on your device) and see which skills in the posting it covers. Free: the score on every job plus one full view a day. |
| 0.1.3 | Built Oct 27, 2026 | Flags postings that say they don't sponsor visas and quotes that sentence. Adds a "Hide on this site" button, short company names in search (BCG, AWS…), and the data years and sources at the top of the panel. Uses less CPU on job pages. |
| 0.1.2 | Built Oct 27, 2026 | Pro data now comes from the snapshot bundled in the extension. Removed the server fetch and its host permission. |

Reviews
We only show reviews that real users posted on a browser store, quoted word for word with a link to the review. We don't write, buy, swap or ask for reviews in exchange for anything, and we don't use testimonials, star ratings or user counts from anywhere else.
Right now there are none to show. As of 2026-11-01, H1B Sponsor Checker has no ratings or reviews on the Chrome Web Store or Firefox Add-ons. Our policy: we only quote real store reviews, good or bad, with a link.
