A Graduate visa gives you permission to stay in the UK for at least 2 years after successfully completing a course in the UK. You must be in the UK when you apply.
You can apply for a Graduate visa if all of the following are true:
you’re in the UK
your current visa is a Student visa or Tier 4 (General) student visa
you studied a UK bachelor’s degree, postgraduate degree or other eligible course for a minimum period of time with your Student visa or Tier 4 (General) student visa
your education provider (such as your university or college) has told the Home Office you’ve successfully completed your course
You can ask your education provider if you’re not sure whether they’ve told the Home Office you’ve successfully completed your course.
A Graduate visa lasts for 2 years. If you have a PHD or other doctoral qualification, it will last for 3 years. Your visa will start from the day your application is approved.
You cannot extend your Graduate visa. However, you may be able to switch to a different visa, for example a Skilled Worker Visa.
