From 6 April 2015, the term 'Highly Trusted Sponsor' will be replaced by 'Tier 4 Sponsor' and 'A-rated sponsor' will be replaced by 'Probationary Sponsor'. We have been advised that these terms better reflect the nature of the different types of sponsor status. UKVI will be publishing further guidance (expected at the end of March 2015) which will reflect this change.
Tier 4 sponsors should note that at this stage this is a change in terminology only and UKVI has not indicated whether there will be changes to the HTS criteria itself. Sponsors should therefore continue to monitor their HTS statistics.
