ATAS - Academic Technology Approval Scheme

What is ATAS  

ATAS is a certificate issued by the Foreign Commonwealth and Development Office (FCDO), which gives international students and researchers security clearance to study or carry out research in certain sensitive, technology-related areas (e.g. mathematics, engineering, technology, subjects allied to medicine, biological or physical sciences) at postgraduate level or above.  

ATAS certificate is valid for 6 months and it is specific to an institution you are applying to study at and for the study/research declared in your application form.

Your ATAS certificate must accurately reflect your personal details, course dates, programme title and content of your course. 

ATAS requirement depends on the following: 

  • nationality 

  • level of studies 

  • field of studies, which is regulated by the CAH3 code 

CAH3 code (Common Aggregate Hierarchy code) is a subject code linked to courses or research areas offered by Higher Education Institutions (HEIs) or Research Institutions in the UK. 

You only need an ATAS certificate for specific types of study and research at postgraduate level and above. This includes taught or research course at Master’s level (MSci/MEng/MRes) and research at PhD level.  

Those applying for an undergraduate course with an integrated Master's year may also need ATAS clearance. 

If you’re studying for a postgraduate diploma or PGCE, you do not need an ATAS certificate. 

Some nationalities are exempt from the ATAS requirement. 

New Students

If you are studying a research course that requires ATAS clearance, you will receive an ATAS statement from the Admissions team. Your ATAS statement will be at the bottom of the offer letter. The statement should be copied and pasted into your ATAS application as it is. You must not make amendments to it.  

Taught students studying a course that requires ATAS should refer to the Programmes and Modules Handbook for the list of modules from their Master's level year to include in their ATAS application. 

If you have questions or concerns about your ATAS statement, you should contact the Admissions office for further information. 

Continuing Students 

You will need to apply for a new ATAS certificate if you are changing course, research area or modules and the new course or research area is ATAS-attracting.  

You will also need a new ATAS if the completion date of your course of study has changed and will be delayed by more than 3 months. 

Continuing students under the Student visa route, may find additional information on this webpage. Valid ATAS clearance will be required for the purpose of CAS application for a Student visa extension.

You should aim to make your ATAS application 4 months before your current Student visa expires. ATAS applications can take at least 30 working days to process, and even longer during busy periods. 

Student visa 

An ATAS certificate will be required as part of your Student visa route application (both entry clearance and leave to remain application) if you intend to study or research a subject area in the UK that is ATAS attracting. Without this certificate, your visa application will be refused.  

Your ATAS certificate must be valid at the time of making your visa application. You must submit your Student visa application before your ATAS certificate expires. An expired certificate must not be used for any visa applications. If you submit an expired ATAS certificate as part of your Student visa application, your visa application will be refused.  

Standard Visitor route (study for less than 6 months)

Students on a study exchange programme or visiting students studying at the University for less than 6 months may also require ATAS clearance. Even if this short period of study forms part of an overseas postgraduate qualification, you will be required to hold a valid ATAS certificate to study sensitive subjects at the University of Birmingham.  

If an ATAS certificate is required, it must cover the period of any planned study taking place in the UK. 

Short-term students can apply for a Standard Visitor visa before they get an ATAS certificate, however, an ATAS certificate will need to be obtained before any study or research activity begins. 

If you do not require a visa to enter the UK and your programme is ATAS attracting, you will need ATAS before commencing your study or research (unless you are exempt by nationality).  

You should already have a valid ATAS certificate before travelling to the UK to be able to commence your study/research without delay.  

UK residents 

If you are going to study on a non-Student visa (e.g. Skilled worker, Dependent visa), you may still require ATAS clearance to study.  

You do not need to apply for an ATAS certificate if: 

  • you are a British or Irish citizen 

  • you have Indefinite Leave to Remain (ILR) in the UK 

  • you are exempt from UK Immigration Control (e.g. diplomatic visa) 

  • you have pre-settled or settled status granted under the EU Settlement Scheme 

Changes to your course

You will need a new ATAS certificate if your course end date is delayed by 3 months or more. In this situation, you must contact University for further guidance. 

You will also need to apply for a new ATAS certificate in the following circumstances: 

  • the content of your current course changes 

  • your primary supervisor changes 

  • your financial sponsor or conditions for financial sponsorship change at any time during your study or research 

  • you choose to apply for a programme transfer and your new programme requires ATAS (you need to do this even if you already have an ATAS certificate for your current course)

  • you want to move to another university.
