I am Sergey Maiko your personal immigration lawyer specializing in UK work visas. My main goal is to help clients legally and efficiently prepare employment documents, protecting their rights and interests. I specialize in work visas, sponsor licenses, and compliance with immigration requirements for companies and employees.
My experience allows me to guide the process from job preparation and obtaining a sponsor license to issuing a Certificate of Sponsorship Tier 2 UK and submitting a Skilled Worker visa or Tier 2 visa UK application. I help avoid bureaucratic errors and ensure full legal protection when employing foreign workers in the UK under proper UK employer sponsorship.
What is a Certificate of Sponsorship (CoS)?
A Certificate of Sponsorship Tier 2 UK is an electronic document that confirms the employer in the UK is authorized to hire a foreign worker and sponsor their work visa.
Without a valid sponsor license, a company cannot issue a CoS or legally operate in employing foreign workers in the UK.
Main Steps for Hiring a Foreign Worker via CoS
Job Verification
A lawyer checks whether the position meets Home Office requirements for:
- required qualification level;
- minimum salary;
- occupation code (SOC code).
Obtaining a Sponsor License
If the company does not have a license, a document package is prepared for the Home Office, which includes:
- corporate documents;
- HR policies;
- proof of active business operations for UK employer sponsorship.
Compliance with Immigration Procedures
The lawyer advises on labor market requirements, legal exemptions, and procedures required by the Home Office when employing foreign workers in the UK.
Issuing the Certificate of Sponsorship
After receiving the license, the employer issues a Certificate of Sponsorship Tier 2 UK to the specific candidate.
Submitting a Work Visa Application
The foreign worker applies for a Skilled Worker visa or Tier 2 visa UK from outside the UK or from within the UK.
Question
What documents and steps are required for legally employing foreign workers in the UK via CoS?
