Sponsor Licence / Applying COS / SMS Management

A UK Sponsor Licence is required for employers who wish to lawfully sponsor overseas workers under routes such as the Skilled Worker visa. Once a licence is granted, employers must correctly apply for Certificates of Sponsorship (COS) and manage their ongoing duties through the Sponsor Management System (SMS). The Home Office applies strict compliance standards, and failure to meet reporting, record-keeping, or eligibility requirements may result in licence refusal, suspension, or revocation.
