To apply for ATAS you need a statement from the University confirming your research topic.
For new students this is usually sent with your offer letter. If you do not have this statement, and need an ATAS certificate, please contact your Admissions Officer, listed on your offer letter.
Continuing students need to request this from the University of Birmingham's Online Shop.
Once you have your statement from the University you can make your ATAS certificate application online to the Foreign Commonwealth Office (FCO). This should take no longer than 30 minutes to complete.
This site also contains information about the scheme and the list of designated subjects. If you are granted clearance, an ATAS certificate will be issued to you in an email. You must provide a copy of your ATAS clearance certificate with your application.
