Many readers may be aware of or familiar with the Tier 2 sponsorship scheme. This scheme enables non-EEA migrants to work in skilled jobs for UK employers. Such migrants hold Tier 2 Skilled Worker visas – sometimes known under the older terminology as Work Permits. Employers who wish to employ Tier 2 migrants have to hold a Tier 2 sponsor licence. Sponsor licences are jealously guarded by the Home Office, and indeed the whole Tier 2 structure is very strictly governed.
