Student Immigration Service

New students

You can request a CAS as soon as you have accepted an unconditional offer. How long it takes to receive your CAS number depends on your level of study and the time of year.

When to request a CAS 

You can request a CAS as soon as you have accepted an unconditional offer. You cannot request a CAS if you only have a conditional offer. 

There will be a waiting period after you request your CAS. Usually, we will not issue your CAS number until: 

  • 6 months before your programme start date if applying outside the UK  

  • 3 months before your programme start date if applying inside the UK 

However, if you applied through UCAS, your CAS number won't be issued until July at the earliest.
