Plain-English overview

What is the Certificate of Sponsorship?

An electronic sponsorship record assigned by a licensed employer to an eligible worker.

UK immigration applications are decided under the rules and guidance in force when the decision is made. The exact application process can depend on where you apply, your current status and the evidence required for your circumstances.

Who this route is generally designed for

General answer

Licensed sponsors and workers preparing for a sponsored work application.

Being within the intended audience does not by itself mean a person meets every requirement. Definitions, exceptions and suitability rules may also affect an application.

Important points to understand

  • A Certificate of Sponsorship is an electronic record, not a paper certificate.
  • The correct route, occupation code, salary and work details must be recorded.
  • Assignment does not guarantee a successful visa application.
  • Sponsors must follow allocation, reporting and record-keeping requirements.

Application fees, healthcare charge and processing

We do not hard-code a fee or decision time here because those figures can change and may depend on the application location, permission length and dependant applications.

What to check before relying on this route

  1. 1
    Confirm the route is open

    Read the current official overview and eligibility pages.

  2. 2
    Check where you can apply

    Inside-UK switching rules and overseas applications can differ.

  3. 3
    Identify every required condition

    Do not rely on one headline requirement or an old fee table.

    Use regulated advice if your facts are complex

    Previous refusals, overstaying, criminal issues or unusual evidence may need individual advice.
