Certificate of Sponsorship UK Jobs

Once you’ve confirmed your occupation is listed on the relevant visa occupation list and you’re eligible for sponsorship, the next step is finding an employer willing to sponsor you.

You can utilise websites such as Hays, Indeed, and NHS Recruitment to discover advertised jobs. To narrow your search, include “Sponsorship” in the search criteria to find roles from employers currently offering sponsorship opportunities. Reach out to companies you’re interested in by sending your CV and inquiring directly about potential sponsorship options. Additionally, many employers have a “Careers” section on their websites, enabling you to submit your CV proactively. This ensures your details are accessible in their candidate database, ready for consideration when suitable positions arise.

Another effective method is to look for international companies operating in both your home country and the UK. You can initially join the company in your home country and subsequently seek internal transfer opportunities to a UK-based office.

Common Mistakes to Avoid

  • Expired CoS – must be used within 3 months of issue
  • Incorrect job code – must match the Skilled Worker eligible roles list
  • Salary too low – below the threshold, your visa will be refused
  • Wrong type of CoS – defined vs undefined must match your application route
