UK Visas & Immigration (UKVI) have advised that sponsors are now able to apply to renew their allocation of Certificates of Sponsorship (CoS) in Tier 2 (General) .
The present allocations will expire on 5th April 2017.
Some sponsors’ allocations will be "automatically renewed”, in which case nothing is required from the sponsor.
However, UKVI will contact other sponsors via email three months before 5th April 2017, and monthly thereafter, by way of reminder
