Sponsor Licence / Applying COS / SMS Management

UK employers must hold a valid Sponsor Licence to lawfully sponsor overseas workers under the Skilled Worker route. In addition, sponsors are required to correctly apply for Certificates of Sponsorship (CoS) and manage their licence through the Sponsor Management System (SMS) in line with strict Home Office compliance duties. Errors or non-compliance can lead to delays, refusals, suspensions, or licence revocation.
