Who is this page for?

This page is for current University of Hertfordshire students who need a CAS to extend their Student visa.

If you are a new applicant, your CAS will be issued by the International Admissions team. Contact international@herts.ac.uk for queries about your application.

CAS fee and important updates

From 1 October 2026, a £55 CAS fee applies when a new CAS is issued for a visa extension for repeating students.

What this means

• The £55 fee must be paid before your CAS is issued.
• Payment instructions will be sent when your CAS is ready to be issued.
• The fee is non-refundable, even if your visa application is unsuccessful or you decide not to proceed.

Who does not pay the fee?

You are exempt from the CAS fee if you are extending your visa because you are:

• Taking a placement year
• Taking a Study Abroad year
• Serving as a Sabbatical Officer

Thank you for your understanding, and we remain committed to supporting you throughout your studies at the University of Hertfordshire. 

Can I request a CAS?

Important

We cannot issue a CAS if you have:

• Outstanding tuition fee debt
• Any other debt to the University, including a graduation ceremony block

Before issuing a CAS, we will carry out sponsorship and immigration checks. These checks can take several weeks, particularly where UKVI verification is required.

Requests received less than one month before your visa expires may not be processed.

By requesting a CAS, you confirm that you understand and will comply with the conditions of your Student visa.

The University reserves the right not to issue, or to withdraw, a CAS if:

• You have already received a CAS to extend the same course.
• You are not required to attend your course.
• You have completed your course and are waiting for results.
• You have become an overstayer.
• You have breached the conditions of your visa, including work restrictions.
• You do not meet Student visa eligibility requirements.
• There is reason to believe your visa application will be refused.
• You already have a pending UKVI application, such as an asylum, FLR or fee waiver application.

If your visa application is refused

You must inform the Student Immigration Team (Compliance) at sitcompliance@herts.ac.uk.

A CAS can only be used once. Do not reuse a CAS reference, as this may result in a further visa refusal.

How do I request a CAS?

If you need more time to complete your current course

Complete the online CAS request form at least two months before your visa expires if you are applying from within the UK.

You may need to pay additional tuition fees if you are repeating modules. Check with your School and contact Student Finance  at finance-tuition@herts.ac.uk if you are unsure about your fees.

A CAS cannot be issued while tuition fee debt remains outstanding. This includes where you have a ceremony (graduation) block.

CAS deadlines

Applying from within the UK

Submit your CAS request form at least one month before your visa expires.

Applying from overseas for Semester A 2026/27

Applying from overseas for Semester B 2026/27

Applying from overseas for Semester C 2026/27

Late applications

Late CAS requests may not be considered.

If there is insufficient time for a visa application to be processed before teaching starts, you may need to defer your studies.

Does my course require an ATAS certificate?

If your course requires an ATAS certificate, you must obtain a new certificate before a new CAS can be issued.

See the ATAS guidance page for further information.

What if I am progressing to a new course at Hertfordshire?

For example:

• Undergraduate to Master's
• Pre-sessional course to undergraduate degree

Do not complete the online CAS request form.

Your CAS will be issued by the International Admissions team once you have met all offer conditions.

For questions about your offer, contact international@herts.ac.uk

Do I meet the 12-month UK residency requirement?

If you have lived in the UK for 12 months with valid immigration permission and are applying for a visa extension in the UK, you normally meet the financial requirement and do not need to provide evidence of funds.

Short holidays and temporary absences do not normally break the 12-month period.

However, you will need to show funds and provide financial documents if:

• You have not been based in the UK for a significant part of the previous 12 months (for example, three months or more).
• You have completed an overseas placement or Study Abroad year and are returning to the UK to apply for a visa extension.

See the supporting documents guidance for details.

What if I pay more tuition fees after receiving my CAS?

You should inform the Student Immigration Team (Advice) as soon as possible.

Your CAS may need to be updated on the Home Office system.
