If you have been issued with a Student Visa with an ATAS certificate you can only study within the field that you applied for. You must apply for a new ATAS certificate if any of the following changes:
the content of your course changes;
your primary supervisor changes;
your financial sponsor or conditions for financial sponsorship change at any time during your study or research.
Postgraduate researchers on a Student Visa should contact the Immigration Advice Service for further information.Â
