Confirmation of Acceptance for Studies (CAS)
All full-time non-EU students in the University require a CAS in order to apply for or extend a student visa. When a CAS is issued then the University is 'sponsoring' a student under its Tier 4 Sponsor Licence which has a number of strict responsibilities associated with it including the requirement to monitor attendance.
Full-time Doctoral Researchers based at the University are expected to be physically present at the University and therefore will automatically receive a CAS from the University. This CAS is to cover a period of up to 4 years for thesis submission and a further period of up to 7 months for the viva and minor corrections to take place.
If a Doctoral Researcher has been issued a CAS for 4 years (which is the case for a small group of students) and wishes to extend their student visa, then the student can request that a further CAS be issued to incorporate up to a further 7 month period of time from the thesis submission date in order to include the viva examination and period of Corrections (up to 3 months). In the event that the viva outcome is a prescribed period of Major Corrections (up to 12 months) then a CAS will not normally be granted to cover more than 3 months of this period as a Doctoral Researcher is not required to be physically present at the University during the period of Major Corrections and as such cannot be 'sponsored' under the University's Tier 4 Sponsor Licence.
However, in the event that there is an academic case for the student to be physically present at the University for a period of Major Corrections, then there is a procedure by which a Doctoral Researcher can request a CAS for this period. For details of this procedure please see our flowchart (PDF - 41KB)
In the event that the viva outcome is 'Fail' then a CAS will not be granted to cover this period as a Doctoral Researcher is not required to be physically present at the University during the period of thesis re-submission (up to 3 years).
