You will need to contact the CAS Team as soon as possible (by creating an enquiry) if you're an international student arriving late and/or after your registration deadline. Late arrivals are not guaranteed visa approval and your faculty will decide if you get this.
If you do get faculty approval, our CAS Team will let both you and UK Visas and Immigration (UKVI) know. However, if not approved, you may be deferred to join us at a later date.
