You should contact a Visa and Immigration Adviser within the Student Immigration Team who will firstly assess if there is a basis to issue you a Confirmation of Acceptance for Studies (CAS) to extend your Student visa.
Please contact a Visa and Immigration Adviser by logging a query through Ask RGU. If a visa extension is required, the Visa and Immigration Adviser will guide you through the visa application process.
If you are required to extend your Student visa then please be aware that you must have cleared all student debt and have a valid passport.
Please make sure that you either leave the UK or submit a new visa application from within the UK before your current visa expires, to avoid becoming an overstayer. Being an overstayer is a serious breach in UK immigration rules and may impact any future visa applications made in your name.
