What Is a Certificate of Sponsorship Tier 2?
A Certificate of Sponsorship (CoS) is an electronic document confirming that the employer is authorised to hire a foreign worker and sponsor their work visa. Without a valid sponsor licence, a company cannot issue a CoS or legally employ overseas specialists in the UK.
Key Stages of Employing a Foreign Worker
1. Vacancy Assessment
A lawyer checks whether the role meets Home Office requirements regarding:
- skill level
- minimum salary threshold
- correct SOC occupation code
2. Obtaining a Sponsor Licence
If the company does not already hold a licence, a full application package is prepared and submitted to the Home Office, including:
- corporate documents
- HR and compliance policies
- evidence of genuine business activity
3. Immigration Compliance
Where required, the lawyer advises on labour market requirements and applicable exemptions.
4. Issuing the Certificate of Sponsorship
Once the sponsor licence is granted, the employer assigns a CoS to the selected candidate.
5. Skilled Worker Visa Application
The foreign employee applies for a Skilled Worker (Tier 2) visa from abroad or within the UK.
