How to complete your ATAS application form, what you need to prepare and what to do if your application is delayed or refused.

An overview of the application process 

  1. Check your offer letter from the University to see if you need ATAS clearance for your programme.
  2. Get the CAH3 code from your offer letter. 
  3. Create an account on the ATAS website with your email address. We recommend you use an internationally recognised email server, for example Outlook, Hotmail, Yahoo, Gmail or similar (ATAS have experienced difficulties with firewalls for local servers).
  4. Complete and submit the online application form on the ATAS website.
  5. Wait for a decision.
  6. Receive an email about your application (If your ATAS application is successful, you will receive a PDF file with your ATAS certificate in the email).
