A Certificate of sponsorship (CoS) is an electronic record generated on the Sponsor Management System (SMS). Each certificate has its own number which an applicant can use to apply for a visa.
The employer is required to request a CoS from the Home Office through the SMS, on approval it can be assigned to a migrant worker and used in the entry clearance applications.
Earlier the CoS were of two types
- Restricted CoS
- Unrestricted CoS
With effect from 1 Jan 2021, they are now rebranded as
- Defined CoS
- Undefined CoS

These certificates are required for migrants based outside the UK and applying for entry clearance as skilled worker. Earlier this was known as the Restricted CoS and the sponsors were required to apply for this by the 5th of each month and a decision on the same would be received by 11th of the same month.
These certificates are for Skilled Workers applying from inside the UK, and applicants on all other visas. When employers apply for licence they estimate the number of undefined certificates required for workers and temporary workers during the year. The annual allocation of undefined CoS runs from 6 April to 5 April each year.
