A CAS (Confirmation of Acceptance for Studies) is an electronic document created by King's to evidence to the UK Visas & Immigration (UKVI) that you are a genuine student and that King’s will be your educational sponsor for your Student Visa application.

The CAS confirms:

  • The 14 digit CAS number (which you will use to submit your Student Visa application)
  • King’s Sponsor Licence number and address
  • Your personal details (e.g. Name, date of birth and nationality)
  • The passport number you will use when applying for your Student Visa
  • The programme of studies you will study at King’s
  • The start and end date of your programme of studies
  • The address of your primary site of studies
  • What qualifications King’s has used to assess your eligibility to join your programme with us, including that you have met English Language requirements
  • The total tuition fees owed for your first year of study
  • The total tuition fees paid so King’s so far
  • Whether your course represents Academic Progression if you have already studied in the UK on a Student Visa
  • Whether you will require ATAS clearance

The UKVI will access your CAS information via their digital systems and use this information to decide whether to issue you with a Student Visa as well as how long to grant the visa for and what conditions to place on your Student Visa.  Once your Student Visa is granted and you use this to travel to the UK, your stay in the UK is linked to the exact university and programme of studies listed on your CAS, any changes could impact your visa.
