How this index is built

Every sponsorship claim we make traces to a government release you can open yourself. We do not copy community spreadsheets, and we do not ask you to take our word for anything.

Where the sponsorship data comes from

United Kingdom — Register of Licensed Sponsors

The Home Office republishes the full register as a CSV most working days. We discover the current file from the gov.uk Content API rather than hardcoding a URL, so we are never serving a stale snapshot. We keep the A/B licence rating: a B-rating means the licence is on a Home Office action plan, which is a materially riskier bet for a candidate, so we show it rather than flattening it to “sponsor”.

Licensed under the Open Government Licence v3.0, which permits commercial re-use with attribution.

United States — USCIS H-1B Employer Data Hub

This gives us approval counts per employer, not just names. A company with 400 approvals in a year and one with a single approval are both technically sponsors; only one is a realistic target. We show you the number. USCIS publishes by federal fiscal year, so this data trails the present — we label the year on every US role instead of implying it is live.

Netherlands — IND Public Register of Recognised Sponsors

In the Netherlands this is a hard legal gate: only a recognised sponsor may hire a highly skilled migrant, so absence from this register means a company cannot sponsor you however much it wants to. Each entry carries a Chamber of Commerce (KvK) number, which is an exact government-issued identifier — better than any name matching can achieve.

Japan — and why we treat it differently

Japan publishes no register of companies permitted to sponsor. Eligibility for the Engineer / Specialist in Humanities and Highly Skilled Professional routes is assessed per applicant, and any solvent employer may act as the sponsor. There is therefore no registry fact to ingest, and any list claiming to be a verified Japanese sponsor list is someone’s guess.

For Japanese roles we score the posting itself — explicit visa-support language, Certificate of Eligibility mentions, English-language requirements — and label the result as posting-derived rather than government-verified.

How roles get attached to sponsors

Job postings come from companies’ own public applicant-tracking feeds — Greenhouse, Lever, Ashby, SmartRecruiters — so what you see is what the employer is advertising right now, linking straight to their own apply page. We then match each employer to its registry entries.

That matching is the hardest part, and we are deliberately conservative about it. Government registers list legal entities: the UK register calls Deliveroo “Roofoods Ltd t/a Deliveroo”. We resolve trade names, legal-form suffixes and domain-style names, but where one normalised name could refer to two different companies we refuse to guess and leave the role unattributed until a human confirms the match. Telling you a company sponsors when it does not would cost you a real application, and that is the one error we are least willing to make.

What the confidence score means

Strong evidence (72+): A government record for the role’s country and the posting itself mentions sponsorship.
Likely sponsors (45–71): A government record covering the country this role is in.
Weak signal (20–44): Evidence exists but something is off — low sponsorship volume, or a posting that does not state its location.
No evidence (under 20): No registry record and the posting says nothing. We say so.

A posting that rules sponsorship out in its own words overrides everything else, however strong the company’s record. This is the single most useful thing we do: a company can be a major sponsor and still post roles requiring existing work authorisation, and those roles are where people lose weeks.

The index grows as we vet more company job boards. If an employer you care about is missing, tell us and we will add their board.

Limitations, stated plainly

A licence is not an offer. Holding a sponsor licence means a company can sponsor, not that it will sponsor you for a particular role.
US data lags. USCIS publishes annually, so approval counts are historical.
We do not cover every employer. We index companies whose job boards we poll, which is a fraction of every licensed sponsor.
We are not immigration advisers. Nothing here is legal advice. For advice on your own case, consult a regulated adviser.
