A Certificate of Sponsorship (CoS) is a crucial document required by non-UK workers seeking employment in the United Kingdom under the Skilled Worker Visa. This certificate is issued electronically by licensed UK employers, who act as sponsors for foreign workers. The CoS is necessary for workers applying for a Skilled Worker Visa or other work-related visas.

To obtain a Certificate of Sponsorship, the employer must first be registered with the Home Office as an approved sponsor. Once registered, the employer provides the foreign worker with a CoS, which contains a unique reference number. This number is essential for the visa application process and confirms that the job being offered meets the necessary skill level and salary threshold.

The Certificate of Sponsorship is valid for three months, during which time the worker must submit their visa application. It is important to note that the CoS alone does not guarantee a visa; applicants must also meet other visa requirements. The Certificate of Sponsorship is essential for any skilled worker wishing to work in the UK, ensuring that the UK’s immigration laws are followed.
