What Is Certificate of Sponsorship (CoS) UK? Sponsor Licence

A Certificate of Sponsorship (CoS) is a document issued by an employer in the UK to a foreign worker, which allows them to apply for a visa to work in the UK.

The CoS includes information about the job title, salary, and other details of the sponsored job, as well as the unique reference number that foreign workers need to include in their visa application. It is mandatory for most non-European Economic Area (EEA) nationals to have a valid CoS to be eligible to work in the UK as a skilled worker.

My Scotland based business's sponsor licencing application was handled by Mr Rasheed. They have their office in Manchester, and my case was handled remotely without requiring me to go to their office there. I received my sponsor licence in less than six weeks.

Muhammad handled my partners fiancée visa application then at deluxe law chambers also did her subsequent spouse visa application after our marriage. He was very informative and happy to help. Deluxe Law Chambers got us a positive result and I would recommend Muhammad for anyone wanting a lawyer for their immigration that is willing to contact you even outside of work hours to ensure you do not incur extra costs from application fee changes and ensures everything is covered to aid the application.
