The Academic Technology Approval Scheme

The Academic Technology Approval Scheme (ATAS) applies to certain foreign students and researchers who want to study or conduct research in specific sensitive technology-related fields in the UK. The Foreign, Commonwealth & Development Office (FCDO) administers the scheme and issues ATAS certificates.

ATAS only applies to employers who are also holders of a student sponsor licence. For further guidance read: UK visa sponsorship for employers: check whether your worker needs an ATAS certificate

Common terms

We use the following terms in this guidance:

Higher Education Institution (HEI) refers to the university offering a postgraduate programme of study, research or contractual employment.

Research institutionInstitution is an organisation where an individual is employed to conduct research.

Student refers to those undertaking taught courses or research at a Masters or PhD level.

Contracted researcher refers to individuals who are contractually employed by an HEI or Research Institution.

Visiting academic researcher is someone visiting a HEI or Research Institution temporarily (for up to 12 months) to teach or participate in research that doesn’t lead to a UK qualification for them.

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

Standard Occupational Classification (SOC) is a four-digit employment code used to group jobs by the skills and qualifications needed for the role.

Financial sponsor is the person or institution funding your studies or research.

Duplicate application is when an individual tries to submit a new ATAS application, but they already have an existing application in the system in a state of ‘submitted’, ‘accepted’, ‘changes required’ and the:

• date of birth is identical

• passport number is identical

• the CAH 3 Code is identical

• HEI or Research Institution details are identical

Other common terms related to the status and outcome of an ATAS application:

• Submitted is the status of an application when it is received into the ATAS IT system for assessment. You can choose to withdraw your application at this stage.

• Requires Changes is when an error is identified within the ATAS application. You can correct the mistake and resubmit your application or withdraw it at this stage.

• Part-complete is when the application is still being edited and has not been submitted.

You need your ATAS certificate to apply for some UK visas.

Read about how to apply for a visa to come to the UK.

Your ATAS certificate is valid for 6 months for use as part of a visa application from the ATAS certificate’s date of issue. For some visas your ATAS certificate will be checked as part of the visa application process.

Some visas have particular timeframes for when you can apply, for example based on your course start date for a Student visa. You should check the visa requirements on GOV.UK for details before making your visa application.

If you need an ATAS certificate it must be approved before you can start in the UK as a student or contracted researcher. 

The ATAS certificate is valid for the duration of your course or research, as long as you have a valid UK visa.

If your visa expires during your course or research period, you must reapply for a new ATAS certificate and a new UK visa.

If you apply to extend your UK visa before it expires, your current visa conditions will continue while you are waiting for a decision, even if the expiry date passes while you are waiting.

Check when your current visa is due to expire and allow enough time to complete the ATAS application and visa renewal processes.

If you are applying for asylum in the UK, you must also apply for an ATAS certificate for any course or employment that requires one.

If you are already in the UK

If you are already in the UK on a valid UK visa and are changing course or research project, you will still need an ATAS certificate if your new course, research project or employment requires it.

You must provide the HEI or Research Institution with a valid ATAS certificate before starting your new course or area of research.
