ATAS certificate

An Academic Technology Approval Scheme (known as ATAS), is a certificate issued by the Foreign Commonwealth and Development Office (FCDO) which gives you security clearance to study certain subject areas in the UK.

These subject areas relate to where the knowledge gained may have an application in the development or delivery of weapons of mass destruction, for example, certain science subjects such as mathematics, engineering, technology or medicine.

An ATAS certificate will be required as part of your visa application if you intend to study one of these subjects. You might also need a new ATAS certificate if your circumstances change once you have started your course, for example, if your course duration is extended for more than 3 months, or, if the area of your research change during the course.

ATAS is not limited to just the Student visa route. You would also need ATAS if you are going to study your course using other time-limited visa such as Dependant visa, Skilled Worker visa and Standard Visitor visa. In these cases, you do not necessarily need the ATAS certificate to apply for the visa, but you will need the ATAS certificate to study on the course.

You do not require an ATAS if you are:

A UK national
An EU national
A Swiss national
A national of Australia, Canada, Japan, New Zealand, Singapore, South Korea, or the USA

New students

An ATAS clearance certificate is valid for up to six months. After six months, it can no longer be used in an immigration application.

Student route applicants can apply for entry clearance up to six months and permission to stay up to three months before the course start date, so the earliest a student can apply for ATAS clearance depends on where they apply for Student permission, but is well in advance of the date on which their course starts.

You can see if you need an ATAS certificate by checking the following:

Your offer letter from 麻w豆传媒 will state if your programme requires an ATAS certificate.
If you are applying for a Student visa, your CAS (Confirmation of Acceptance for Studies) statement will also state if you are required to obtain an ATAS certificate.

Current students

If you have already started your course and are changing to a different course that requires ATAS, or, if you have been given a period of extension which extends your course end date by more than 3 months, you will need to apply for a new ATAS certificate.

You may need to apply for a new ATAS if you have started your course but the course content or research proposal has since changed. If you are unsure, it is best to obtain a new ATAS certificate.

How do I apply for an ATAS?

ATAS applications are submitted and are free of charge.

You can apply for an ATAS certificate as soon as you have received a conditional or unconditional offer from 麻w豆传媒. As the application may take 20 - 30 working days to be processed, you are advised to apply in good time when you receive your offer for your course. It is recommended that you apply 4 - 6 months before your course start date where possible.

You will receive an email from the FCDO to confirm if your application has been approved or refused.

What information will I need to complete the online ATAS application?
