The University of Nottingham is licensed to issue Certificates of Sponsorship under Tiers 2, 4 and 5.
Investors, entrepreneurs and exceptionally talented people can apply to enter or stay in the UK without needing a job offer - but migrants will need to pass a points-based assessment.
Tier 2 is for migrants who have been offered a skilled job in the UK and the prospective employer is willing to sponsor - migrants can apply to come or remain here to do that job.
Tier 4 is part of the points-based system for immigration. It is for migrants who want to study in the UK.
If an employer in the UK is willing to sponsor you, you may be eligible to come and work in the UK for a short period.
