The first thing we advise here for anyone considering staying in the UK after graduation is to start researching this option early and to use the sources of information and services around you to get an accurate picture of what you can and cannot do, based on your own personal circumstances.
Additionally you should, in conjunction with this, address the wider issues around making Careers choices (using the Careers service and other main sections of this site).
The Tier 1 (Post-Study Work) scheme enables non-EEA students who have recently successfully completed and obtained a degree, Master’s degree, PhD, or postgraduate certificate or diploma to work in the UK for up to two years upon completion of their studies.
You can find details on how to apply for Tier 1 (Post-Study Work) and other work schemes from the Working in the UK website and UKCISA Working in the UK after your studies website and the Oxford Brookes University's website.
We do recommend that once you have done some basic research from the above source you should then get expert support in interpreting how this information affects you by accessing the University’s International Student Advisory Service.
Remember that you can also visit other useful websites for International Students via the "useful links" section of the UKCISA website.
See the International Graduate Jobs section of the Graduate Prospects website to explore options for work in the UK and abroad.
