Extending your submission date

Your submission date

For PhD, EdD, MSc and MLitt students
your submission date is set at four years from your admission date for full-time students and seven years from your admission date for part-time students. You can find your submission date under 'Thesis Submission Details' on the academic tile in your CamSIS self-service. All applications to extend the submission date for these programmes must be made via your CamSIS self-service account (please see below under 'Submitting your application').

For MPhil and MEd students, your submission date is set within one year for full-time students and within two years for part-time students. You can find the submission date for your course on the submitting and examination page of the Cambridge Students website.

Students on the MPhil by Advanced Study, Master of Education (MEd) and Master of Research (MRes) who need to apply for an extension to a submission deadline for assessed work, should contact the programme administrator in the first instance.  Short deadlines which would not impact on the dates on which the student’s marks would be considered by the Exam Board and Degree Committee can normally be considered locally.  For longer extensions, students should initiate an application for an extension via their CamSIS self-service account (please see below). For the MPhil by Thesis and Oral all applications must be made via your CamSIS self-service account regardless of the length of the extension.

For applications made via CamSIS self-service, each case is considered in line with the policy of Board of Graduate Studies, which is set out in the guidance on this page. 

If you don’t submit your thesis by your submission date and you do not have an extension approved, you will be removed from the Register of Graduate Students, and would only be re-instated upon submission of your thesis. You can find more information about the effects of this on the Removal from the Register page.

Submitting your application

Instructions on how to submit an application can be found on the 'Applying for a change in your student status' page.

Please be aware that if your submission deadline falls over a weekend you will be required to submit by 5.30pm on the Friday before. You are therefore advised to request an extension date that falls on a weekday. You can check this using this tool.

Your application will be considered by your supervisor, department, College and Degree Committee before arriving at the Student Registry for the final decision.

All requests for an extension must address two key questions:

1. Why have you been delayed in submitting your thesis?

2. Why is it essential that you remain on the register beyond your current submission date?

For an application to be approved, valid responses must be provided to these questions.  


Please note that applications submitted after your submission deadline will be declined.

Valid reasons for an extension

  • Unavoidable delay: 

    Examples of this might be a lab move, equipment failure or political unrest in a fieldwork area. The delay must be caused by something out of your own control.

  • Academic reasons: 

    Where there is a strong academic case that you are actively working on the final stages of your thesis and need a short extension to enable you to submit. You must provide a clear timeline for your submission and explain why it is essential for you to remain registered as a graduate student at this stage. If you need to keep access to University resources, you must be specific about which resources these are and why they are essential to the completion of your thesis. Your department and Degree Committee will need to provide the Student Registry with a detailed case if they wish to support your application.

  • A short delay of no more than one month due to medical issues or grave cause: 

    Students who find themselves unable to study because of medical reasons or family emergencies should apply for intermission. For this reason, applications for extensions based on medical grounds or grave cause are limited to one month.

    If your application is for medical reasons, you will need to include supporting medical documents from your medical practitioner or from the University’s Counselling Service.

  • Extension due to disability:

    If you will be unable to submit your thesis by your submission deadline for disability-related reasons, you may apply, in advance, for an extension to your final registration date. If you intend to apply for an extension, you may find it helpful to discuss the timing of this and the impact of your disability on your academic work, with the Disability Resource Centre. You will need to provide clear specialist evidence in support of an application for an extension, for example a report by a medical professional. If you receive support from the Disability Resource Centre, a Student Support Document or a supporting statement from them, will also be taken into account when your application is considered.

Invalid reasons for an extension

  • Visa issues
  • Medical issues or family circumstances, where a period of intermission should have been requested
  • Attending conferences
  • Writing papers
  • Undertaking further research, unless your supervisor, department or Degree Committee make a very strong academic case for this
  • Employment
  • Not wishing to leave Cambridge
  • Continued funding


Information for students studying on a Tier 4 sponsored visa

If your application to extend your submission date is approved, but you will still be able to submit your thesis and complete your examination within the validity of your current visa, there will be no further implications. 

If your application to extend your submission deadline is approved and your new submission deadline means you need to extend your Tier 4 visa, you must contact the International Student Office for guidance on the application process and requirements as soon as possible.

If your application to extend your submission deadline is not approved, and you submit your thesis before your submission deadline, there are no implications for your Tier 4 visa. If however you do not submit your thesis by your submission deadline and are removed from the Register of Graduate students, this will have implications for your Tier 4 visa. You should contact the International Student Office to discuss this.

It is advisable to contact the International Student Office to check the implications of any change of circumstances on your visa status: (
