What is a Sponsor License?

A Sponsor License is necessary for any company that wishes to employ a non-EEA national for their UK-based business. These workers will need a Certificate of Sponsorship before they apply for their Tier 2 or Tier 5 Work Visa. The Sponsor License allows a company to apply for a Certificate of Sponsorship to be issued to a person they have offered a job in the UK.

UK sponsors will need to follow their duties outlined by the Home Office to keep their Sponsor License. These include undertaking the RLMT and making sure their employees meet the requirements of their visa.

What is an illegal worker in the UK?

An illegal worker is anyone from outside the EEA who is currently working in the UK without a visa or work permit which allows them to do so.
