If you are already resident in the UK under a different visa category (e.g. Skilled Worker, PBS Dependant, ILR etc.) then it may be possible for you study part-time. As per the information above, there must be a validated part-time route available for the course you are hoping to join.
Study is restricted under the Graduate Route visa - you cannot study a course for which in theory a Student Route visa could be obtained. Study that is permitted on the Graduate Route include: evening classes or recreational courses, study at a college/provider that doesn’t hold a Student sponsor licence, some professional courses. Please check with the course provider.
You should also consider whether you have enough time within your current immigration leave to complete the course in its entirety. If you do not have enough time for the whole course, you will need to ensure that you are confident you can extend your current visa or "switch" into another visa category in order to complete. It is important to note that you would not normally be able to gain any subsequent Swansea University Student visa sponsorship for a part-time course, and should not presume that switching to a Part-Time Student visa would be a future option (though switching into the Student Route to continue your course on a full-time basis may be possible).
Please note: if you are coming as a Visiting Researcher/Academic, or for a short visit as part of an exchange programme, then the University will confirm the correct visa to apply for, though you may also like to look at our Visiting Academics and Researchers section.
If you need help verifying your immigration status, please send a copy of your visa to the VISA Advice team via email and they will check your options with you.
