When to apply
You can apply for your Student visa up to six months before the start date of your course if outside of the UK or three months before if you are extending in the UK.
The time required to process your visa will depend on the country where you are making your application, but is likely to take around two months. The GOV.UK website lists recent processing times for visa applications from different countries.
You should wait until you have obtained your successful visa decision letter and vignette in your passport before you book any non-refundable travel tickets.
It is advisable to start the process early.
You must use the information on your Confirmation of Acceptance for Study (CAS) email, sent to you by us to apply for your Student visa.
Your CAS must not be more than six months old when you apply for your Student visa. If you use it after this date, your application will be refused.
