Tier 5 visas are part of the points-based system for temporary workers wanting to work in the UK
This Tier was first introduced to the UK in November 2008
If you meet the immigration rules of this visa route, a UK employer (sponsor) is required to issue you a Certificate of Sponsorship
Different rules apply for Charity Workers and the Youth Mobility Scheme to other Tier 5 visas
Tier 5 visas are only issued for 12 or 24 months and cannot be extended beyond their respective permission periods
