International students aiming for postgraduate studies in fields like engineering or biotechnology in the UK must obtain an Academic Technology Approval Scheme (ATAS) certificate. This clearance ensures your studies meet UK security standards. Starting your application early in 2025 prevents delays in your Student visa process.
What is an ATAS Certificate?
The ATAS certificate is a UK government check run by the Foreign, Commonwealth & Development Office (FCDO). It applies to specific postgraduate courses or research that could involve sensitive technology, such as nuclear science or advanced materials. In 2025, it’s required for non-exempt international students before they can get a student visa. The certificate proves your studies are safe and won’t harm national security.
Who Needs an ATAS Certificate in 2025?
Not every student needs this certificate. It depends on your nationality and course.
Exempt Nationalities
You don’t need an ATAS certificate if you’re from:
- Australia, Canada, Japan, New Zealand, South Korea, Singapore, or the United States.
- EU/EEA countries, including Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, or Switzerland.
If you hold a valid passport from these countries or have dual nationality with one, you’re exempt. Postgraduate diplomas and PGCE courses don’t require ATAS either.
Eligible Courses
ATAS applies to postgraduate programs like Masters, PhDs, or integrated undergraduate Masters in fields such as:
- Aerospace engineering
- Biotechnology
- Physics or chemistry (specific areas)
- Materials science
- Nuclear technology
Ask your university for the Common Aggregate Hierarchy level 3 (CAH3) code to confirm if your course qualifies. For research programs, include project details; for taught courses, list all modules.
How to Apply for an ATAS Certificate: Step-by-Step
Follow these steps to apply for your ATAS certificate in 2025. Start after you receive your university offer, as you’ll need specific details.
- Check Eligibility and Collect Details
Confirm with your university if your course needs ATAS clearance. Get the CAH3 code from your offer letter. Visit the official ATAS guidance page for subject details. - Set Up an Account
Go to the ATAS application portal. Use a non-Gmail email address, as Gmail may not receive confirmation emails. - Fill Out the Application Form
Choose “Taught/research student” as your applicant type. Select “Taught” for structured courses (e.g., MSc, MEng) or “Research” for PhDs or research Masters. Enter:- Personal information: Full name, date of birth, passport number, current address.
- Education history: List all previous university studies.
- Job history: Include past roles and explain any gaps.
- Course or research details: Provide module lists for taught courses or a project summary for research.
- Referees: Give contact details for two people (one academic, one from your home country, known for 3+ years).
- Funding: Mention your funding source, like scholarships or government support.
- Personal statement: Explain why you’re studying and your plans after graduation.
If your spouse is joining you and studying a sensitive subject, note this—they’ll need their own certificate.
- Check and Submit
Review your form carefully. Mistakes, like wrong passport numbers, can delay your visa. Submit the form—you can’t change most details after this, except passport or referee information. - Track Your Application
Check your application status on the portal. If your course details change (e.g., modules, supervisor, or end date delayed by over three months), email ATAS@fcdo.gov.uk and reapply. - Get and Use Your Certificate
If approved, you’ll receive a PDF certificate by email, valid for six months. Include it in your UK student visa application.
Documents and Information Needed
Before applying, gather:
- University offer letter with CAH3 code.
- Passport details (current or expired if in the UK).
- Academic transcripts from past studies.
- CV with relevant work experience.
- Referee contact details.
- Funding information (or note if not confirmed).
You don’t upload documents; just type the details into the form.
Processing Times and Costs
| Detail | Information |
|---|---|
| Cost | Free—no application fee. |
| Processing Time | At least 30 working days (6 weeks); longer during April–August. |
| Fast-Track | Not available; apply 3–4 months before your visa deadline. |
If you don’t hear back after four months and your visa is expiring, email ATAS@fcdo.gov.uk with your reference number.
Common Application Mistakes to Avoid
- Using a Gmail address for registration, which may block emails—use another email provider.
- Sending multiple applications, which stops processing.
- Leaving out module lists or research details, which can lead to rejection.
- Misclassifying your course as taught or research—check with your university.
Rejections often happen due to unclear funding or incomplete research descriptions. If refused, appeal with a letter from your supervisor.
FAQs
What if my course changes after getting ATAS?
You must apply for a new certificate if your course content, supervisor, or end date changes significantly.
Do short-term courses need ATAS?
Yes, if the course involves sensitive subjects, even if under six months.
Can my spouse apply with me?
No, they need a separate application if studying an ATAS-relevant course.
Is ATAS required for visa extensions?
Yes, if extending for an ATAS-eligible course; apply before your current visa expires.
