The T5 category (formerly Tier 5) is for migrants who wish to come to the UK for temporary work. Migrant workers will usually be able to work in the UK for up to 12 months or less.

There are 6 types of T5 visas:

1. Creative and sporting visa: for sportspeople, entertainers or creative artists entering the UK for short-term engagements.
You can switch into this category if you are in the UK as a sports or entertainer visitor and you have a Certificate of Sponsorship assigned to you before you come to the UK.

2. Charity worker visa: for voluntary workers who wish to do unpaid work for a registered charity

3. Religious worker visa: for those who want to do religious work on a temporary basis. Those wishing to undertake permanent religious work can apply as Minister of Religion. You can come to the UK for up to 24 months

4. Government authorised exchange worker: is for those who are coming to the UK to share knowledge and experience i.e. through work experience and placements.
