When can I make my Tier 4 DES application?
You must apply for this extension within the 60 day period before your current PhD course end date to be eligible for this Scheme.
We recommend that you submit a Tier 4 DES CAS request form at the time of your thesis submission. Once you have undertaken your viva, IST will advise you on when you will be eligible to make a Tier 4 DES application.
