The register
The register lists Oaoa in London as a licensed sponsor on Skilled Worker, an entry that goes back to at least 2026. Rating on the current register: Worker (A rating).
Companies House lists it as Oaoa Ltd, number 08250133, incorporated 2012: 14 years of filings behind the name. Registered office: 67a Jeddo Road, London, W12 9ED, W12 9ED. Its filed activity puts it in professional and technical services.
A licence says an organisation may sponsor; it does not say it is hiring today. The way to find out is the same as for any employer: the careers page, the job boards, and a direct approach with a UK-style CV that says early that sponsorship would be needed.
