Introduction to Certificate of Sponsorship (CoS) in the UK
A Certificate of Sponsorship (CoS) is not an actual physical document but rather a unique reference number that holds details about the job and the prospective employee’s personal information. It is an essential part of the UK visa application process for Tier 2 and Tier 5 visas. Employers must first obtain this number from the UK government before an overseas employee applies for a work visa.
Who Needs a Certificate of Sponsorship (CoS)?
An employer in the UK who wishes to sponsor an overseas national for a Skilled worker visa, which was previously known as a Tier 2 visa or Tier 5 visa, must first obtain a CoS. Likewise, the prospective employee requires this certificate as part of their work visa application. The CoS is often divided into two categories:
1. Restricted CoS: Generally for new hires from outside the European Economic Area (EEA).
2. Unrestricted CoS: For employees already in the UK, perhaps switching from another visa type or extending their current work visa.
Essential Documents Required for CoS: Employer Checklist
To obtain a CoS, employers must supply the following documents:
Business and Sponsorship Licence Details
Before you can even think about the CoS, make sure your Sponsor Licence is in order. You'll need to provide:
- A copy of your Sponsor Licence approval letter
- Any correspondence related to your Sponsor Management System (SMS)
Job Description and Justification
- A comprehensive job description
- The details about the salary and whether it meets the appropriate rate
- Justification for hiring overseas, including recruitment history
Candidate Details
