Post-Study Work Visa will be open to all students, on Tier 4 visas, who are accepted onto a course in the 2020 intake or later. Once you have successfully completed a course of study at the undergraduate level or above at an approved UK Higher Education Provider you would be able to stay and work (in any sector or at any level) for a maximum of two years.
The full details and requirements are yet to be announced by the UK Government, but will be updated here when made available.
