All non-EEA students who need a student visa to study in the UK will be required to apply for ATAS clearance before applying for a Tier 4 (General) student visa.

PLEASE NOTE that an ATAS certificate is only valid for 6 months from the date of issue. You must make sure that you submit your visa application before the ATAS expires!

You should apply for ATAS clearance well in advance (at least one month) of your student visa application as the processing time for ATAS can be as long as 20 working days.

NB: In addition to the above, during the months of July, August and September, ATAS is extremely busy and so the processing time for ATAS applications can be as long as 30 working days.

CAH3 course code is CAH10-01-08

You will need to include a short description about the research work to be undertaken in your ATAS application. This has to be written by your supervisor. Please contact your supervisor for this. August is the main holiday month in the UK so if you are due to start in October we recommend that you contact your supervisor for the research statement before end July.

We receive many queries about how to complete sections of the ATAS application. Please refer to our ATAS FAQ [pdf] and FCO examples of proposed research [pdf] in the first instance as your query may easily be resolved.
