ATAS (Academic Technology Approval Scheme) is a free security clearance certificate that some international students need before studying certain sensitive subjects at postgraduate level in the UK. Nigerian students usually need one for those courses. If your course requires it, you apply online and the university cannot confirm your place for visa purposes until you have the certificate.
What is an ATAS certificate?
ATAS is run by the UK government to protect sensitive technology and knowledge. It applies to some postgraduate courses (mostly Master’s and research degrees) in areas such as certain sciences, engineering and technology subjects. The certificate confirms that you have been cleared to study that course at that university.
Do Nigerian students need ATAS?
ATAS applies to students who are not from the UK, the EEA, Switzerland or a small list of exempt countries. Nigerian citizens are generally not exempt, so if your course is covered, you need ATAS. Check the list of exemptions on gov.uk, since it can change.
Which courses need ATAS?
The requirement depends on the subject code of the specific course, not the course name alone. Examples of subject areas that have been covered include some engineering, advanced computing, physical sciences and biology-related areas. Your university will tell you in the offer or on the course page whether your course needs ATAS. Do not guess from the title.
| Step | What to do |
|---|---|
| 1. Ask the university | Confirm if your course needs ATAS and ask for the course code and research details if needed |
| 2. Gather details | Passport details, university name, course details and a short description of the research or modules (for research degrees) |
| 3. Apply online | Use the official gov.uk ATAS application; it is free |
| 4. Wait for the decision | Processing can take several weeks. Apply as soon as you have the details |
| 5. Send the certificate | Give the ATAS number to the university so it can issue your CAS |
Timing: why you should apply early
Processing time varies, and busy periods are longer. Delays can push back your CAS, your visa application and even your start date. See our September 2027 application timeline and plan ATAS inside it.
Important points about ATAS

- Applying for ATAS is free on the official gov.uk site. Be careful with websites asking for payment.
- Do not wait until you get a CAS to start; many universities want the certificate before issuing a CAS.
- Keep the certificate with your visa documents. See how to prepare documents for a UK visa.
