Frequently Asked Questions

A Certificate of Sponsorship is an electronic reference number issued by UK licensed sponsors to enable foreign workers to apply for UK work visas. It's not a physical document but a unique reference number that contains details about your job offer and sponsor.

A COS is valid for 3 months from the date it is assigned. You must submit your visa application within this 3-month period. The visa application must also be made within 3 months of the job start date stated on the COS.

The Health and Care Worker visa is for qualified doctors, nurses, health professionals, and adult social care workers coming to work in the UK. It offers reduced visa fees and exemption from the Immigration Health Surcharge. Eligible roles must be in specific SOC codes approved by the Home Office.

Contact your sponsor immediately if you notice any errors in your COS details. Your sponsor can withdraw the incorrect COS and assign a new one with the correct information. Do not submit a visa application with incorrect COS details.
