From 22 February 2010, any student who applies by post or at one of the UKBA's public enquiry offices to study in the UK under Tier 4 of the points-based system must possess a confirmation of acceptance for studies (CAS) from their prospective sponsor.

Applicants will not be able to apply under Tier 4 using a visa letter from 22 February 2010, even if the visa letter was issued before that date.

Until 21 February 2010, applicants can continue to apply under Tier 4 using a visa letter, even if their course of study will start after 22 February 2010.

For more information about applying to study under Tier 4 of the points-based system, see the Studying in the UK section of the UKBA's website.
