Certificates of Sponsorship

Having been granted a sponsor licence, the next step in employing a migrant worker is often an application for a Certificate of Sponsorship (“CoS”). However, before you can do this, you must be sure you have checked the eligibility of the job you want to sponsor.

Only businesses with a sponsorship licence can obtain a CoS.

What is a Certificate of Sponsorship? 

A CoS is an electronic document issued by a sponsor to enable an applicant to apply for a visa under a category of the Points-Based System, such as the Skilled Worker, Intra Company Worker or Temporary Worker route.

There are two types of Skilled Worker CoS: Defined Certificates of Sponsorship (“DCoS”) and Undefined Certificates of Sponsorship. The type of CoS that a company requires depends on the migrant worker’s circumstances and the vacancy that the migrant will fill.

Under the changes introduced in December 2020 an application for a DCoS can be submitted at any time, and will usually be assessed within 48 hours. However, UKVI are increasingly requesting additional information following a DCoS request, and it is therefore vital to be prepared to provide this information on request. This is likely to include details of how the candidate was identified or recruited.

Applications for a CoS are made via the Home Office’s Sponsor Management System. Once a CoS is approved, it needs to be allocated to the migrant it is intended for before the migrant is able to apply for their visa.

Annual CoS Allocation

Every year the Home Office allows companies holding a sponsor licence to apply for an allocation of Unrestricted Certificates of Sponsorship. The application requires the company to justify the number of CoSs they apply for.

Gherson is able to advise and assist with all aspects of the CoS application process.
