SponsorLens

About

The UK Home Office publishes a full list of every company licensed to sponsor a work visa. Public, free, updated regularly. Nobody checks it while browsing LinkedIn because it is buried on GOV.UK and completely unusable mid job search.
SponsorLens checks it for you. It reads the company name on a LinkedIn job listing and looks it up against the register in the background. No copy-pasting, no tab-switching, no applying to a company that cannot sponsor you and finding out in round three.
You get a small badge next to the company name. Green means the company holds a licence for your specific visa route. Amber means a licence exists but not for the route you care about. A neutral badge means a licence exists but you have not set a route preference yet. No badge means the company is not on the register.
Hover the info icon and you see every visa route that company holds, plus when the data was last updated. Click the badge and it takes you to the GOV.UK sponsor register so you can check with your own eyes.
Setup is one page, one time. After install, an onboarding page opens automatically. Confirm you are looking for UK roles, pick your preferred visa route from a dropdown, done. SponsorLens runs quietly after that. No account, no wizard, no emails.
Your data does not go anywhere. The sponsor register is downloaded once and cached locally in your browser. There is no backend, no analytics, no server receiving anything. The only external call the extension makes is fetching the public register from GitHub. If you want to verify that, the code is there to read.
A few honest limitations. Company name matching is not perfect. LinkedIn shows trading names; the register uses legal names. SponsorLens uses a five-strategy matching approach to bridge that gap and always shows you the matched legal name so you can sanity check it. Treat the badge as a fast signal, not a legal guarantee. The GOV.UK link is there for a reason.
The register covers Worker and Temporary Worker routes. Student sponsorship is not in scope. If SponsorLens cannot find a match, it shows nothing rather than a red badge. Silence means no match found, not that the company definitely has no licence.
Data comes from the UK Sponsor Data project, which processes the Home Office CSV. SponsorLens checks for updates every 24 hours.
Free. No ads. No upsell.
