The Skilled Worker visa is the main UK route for foreign nationals with a job offer from a British employer. Its logic is simple and strict: a UK employer that holds a sponsor licence offers you an eligible job, assigns you a Certificate of Sponsorship (CoS), and you apply for the visa using that certificate. No licensed sponsor, no CoS, no visa — the job offer from a licensed sponsor comes first, and everything else follows from it.
This guide introduces the UK work and sponsorship routes in general terms — licensed sponsors, the Certificate of Sponsorship, and the broad shape of eligibility. Category names and the sponsorship mechanics change slowly, but salary thresholds, fees, and processing times change often, so this guide points you to the official pages wherever a number matters. Always confirm current requirements on the official GOV.UK pages named in the Sources line before you make plans.
Key routes and visa types
Licensed sponsors, the Certificate of Sponsorship, and the main routes.
Licensed sponsors — the register on GOV.UK. A UK employer can only sponsor a Skilled Worker visa if it holds a sponsor licence from UK Visas and Immigration. The official register of licensed sponsors is published on GOV.UK, and anyone can search it — before you invest hope in a job lead, check whether the employer is on the list. Applying to unlicensed employers for sponsored roles wastes your time and theirs.
The Certificate of Sponsorship (CoS). The CoS is not a paper certificate — it is an electronic reference number your sponsor assigns to you through the Home Office system, confirming the job details and that the role meets the route’s requirements. You enter the CoS number in your visa application. Each certificate is unique to one worker and one role.
Skilled Worker — the main route. With a CoS from a licensed sponsor, you apply for the Skilled Worker visa. In general terms, the role must be at an eligible skill level, you must meet an English language requirement, and the salary must meet the route’s thresholds — which are updated from time to time. Check the official pages for the current thresholds, fees, and processing times rather than relying on any figure quoted elsewhere.
Other work routes, in general terms. Beyond Skilled Worker, the UK system includes routes such as the Health and Care Worker visa for eligible medical roles with a licensed sponsor, and the Global Talent route for leaders and potential leaders in academia, research, arts, and digital technology (which does not require a job offer in the same way). These are specialist routes with their own detailed rules — the official pages describe each one.
How sponsorship works, in general. The shape is consistent: you secure a job offer from a licensed sponsor, the sponsor assigns your CoS, and you apply for the visa with the CoS number plus evidence on identity, funds, and English language as the rules require. Because the sponsor starts the process, your first practical step is always the job search — targeted at licensed sponsors, and with sponsorship needs stated upfront.
For current salary thresholds, application fees, and processing times, check the official pages — these change, and an old number can mislead. The Sources line below names the official starting point.
