What is ATAS clearance?
Who needs ATAS?
You'll need to apply for ATAS clearance if the following apply:
- You're applying for a time-limited visa (a visa with a start and end date). This includes a Student visa.
- You're studying or conducting research in a sensitive subject area. A list of these subject areas is available in the ATAS section of the Immigration Rules.
- You're not a national from:
- UK/EU/EEA
- Australia
- Canada
- Japan
- New Zealand
- Singapore
- South Korea
- United States of America
Important to know: If you're a dual national/citizen of one of the countries listed above, you don't need an ATAS certificate. However, you must have a valid passport for the exempt country and your UK visa must be linked to this passport.
Do I need an ATAS certificate?
Your offer letter from King's will confirm whether you need an ATAS certificate as one of your offer conditions. Contact the Admissions team through the King's Apply portal if you're unsure.
If you're applying for a new visa (either in the UK or overseas) to continue a course you are currently studying, or to resume studies that you interrupted, you'll need to apply for a new ATAS certificate.
How do I apply for ATAS?
ATAS clearance applications are made on the Academic Technology Approval Scheme (ATAS) webpage. You'll need your offer letter and your CAH3 code (a code for classifying academic subjects), which will be stated in your offer letter.
What if I need help with completing my ATAS application?
Have a look at our article Making an ATAS application for guidance on completing your application.
When should I submit my application?
ATAS clearance is valid for 6 months, so if your course starts in September, you could make your ATAS application any time after April.
We would recommend applying as early as you can, to avoid delays in receiving your ATAS certificate. Please be advised that you can't apply for your visa until you have received your ATAS certificate.
When will I receive my ATAS certificate?
ATAS applications take at least 20 working days to be processed. Between April and September applications can take over 30 working days.
Each ATAS application is specific to the course you applied for. If you have applied for more than one course that requires ATAS, you would need to submit a separate ATAS application for each course.
What happens once I get my ATAS certificate?
What if 30 working days have passed and I haven't received my ATAS certificate?
Please contact the Visa & International Student Advice team and we can ask for an update on your application. We can't ask for an update unless 30 working days have passed and can't ask the ATAS team to expedite your application.
If your ATAS application is refused, you should contact the Visa & International Student Advice team so that you can discuss your options with them. You can request a review of the decision within 30 calendar days of receiving the decision email.
You can also submit a new application. However, if you want to make an application using the same CAH3 code, in the same area of research and at the same institution, you must wait 90 days from the date of your refusal. If you try to reapply before the 90 days has passed, your application will be blocked by the ATAS system.
We strongly recommend that you don't request a review or make a new application until you've contacted the Visa & International Student Advice team.
