Student Visa extension for postgraduate research students

You will need a new CAS number to apply for a Student Visa extension. 

Please follow the steps on this page to request a new CAS number. 

On the same page, you can also request for our guide to help you prepare the Student Visa application. 

If your programme requires ATAS, you must apply for fresh ATAS clearance. You should do this immediately, as there are often significant delays with ATAS clearance and your clearance may take several weeks to be issued. We cannot issue a CAS without fresh ATAS clearance, but you should still submit your CAS request while you wait for your ATAS certificate to be issued.  

You should ensure that you apply for ATAS clearance as a postgraduate research student, not a researcher. Please use your research statement to help you to complete the ATAS application form. 

It is a UKVI requirement that the University holds evidence of a student’s right to study in the UK. We will require evidence of your visa application and then your new immigration permission to confirm your continuing right to study. 

Please see the Visa Support Team web pages for details of how to submit evidence of both your visa application and your new visa. You must submit evidence of your visa application or new visa before your current visa expires, even if you are changing your immigration permission. 

If we do not receive evidence of your ongoing right to study in the UK before your visa expires, we may suspend your access to some University facilities and, in some cases, remove your registration from your programme.
