If your visa is expiring and you think you may need to extend it to complete your studies, we recommend to first check our webpages as to whether you will be eligible for a new CAS to extend your student visa, as there are a number of factors that we must take into account. The webpages also have instructions on how to apply for a new CAS to extend your visa.
Please make sure to do this in plenty of time before your visa expires as it can take up to 10 working days to process your request.
Once you have received your CAS, if you need any help with your student visa application please visit our International Student Advice Service webpage..
