Do you need an ATAS certificate?
It is free and the form is short. The problem is the six week wait sitting in front of your visa application, which people routinely discover far too late.

Dual nationals can use an exempt country's passport if they hold a valid one.
Answer
Possibly, and your CAS will say
Nigeria is not on the exemption list and your course level is in scope, so it comes down to your subject. Your university assesses this and records the answer on your CAS. Check there before assuming either way.
If it does apply: it is free, and it takes at least 30 working days, longer between April and August.
That wait sits in front of your visa application, not alongside it. Anyone charging you to submit an ATAS application is charging for form filling.
What this can and cannot tell you
It can rule you out, on nationality or course level, and those two account for most people asking.
It cannot rule you in. The requirement turns on your exact subject, and your university makes that assessment and records it on your CAS. Read that rather than guessing from a course title.
Why the timing matters so much
Six weeks sits before your visa application, not alongside it. Add the three weeks a decision usually takes and you are looking at more than two months between needing ATAS and holding a visa, assuming nothing slips.
The busiest period is April to August, which is exactly when September intake applicants arrive at once. If it applies to you, start it first, not last. How it fits the rest of the timeline.
Common questions
- Do Nigerian students need ATAS?
- Nigeria is not on the exemption list, so if your course is one of the sensitive technology subjects the scheme covers at master's or PhD level, yes. Your CAS states whether it applies.
- How much does ATAS cost?
- Nothing. The application is free, so anyone charging you for it is charging for form filling.
- How long does ATAS take?
- At least 30 working days, roughly six weeks, and longer between April and August when volumes peak.
- How do I know for certain?
- Your CAS. Your university assesses whether your specific course and nationality trigger the requirement and records the answer there.
