The Doctorate Extension Scheme is designed for international PhD students.
If you are nearing the end of your PhD studies, you can apply to stay in the UK for a further year under the Doctorate Extension Scheme, which comes under the Tier 4 route. The Doctorate Extension Scheme (DES) aims to give PhD graduates from outside the EU the opportunity to work in the UK for a year once they have completed the PhD. Students who hold this visa can undertake most forms of work on a full or part-time basis, including self-employment, but cannot work as a doctor or dentist in training or a professional sportsperson or coach.
