How to process the expiry date of visa in the application form? I haven't yet applied for tire4 student visa.

Hi Nan - thanks for your question - you can find out more about working visas from the UK Border Agency website, at https://www.gov.uk/government/organisations/uk-visas-and-immigration

Then, depending on the start date of the programme you want to apply for, you’ll need to submit your application to us before the following dates:

For programmes with an April 2021 intake, your application must be received by 2 October 2020.
For programmes with an August or September 2021 intake, your application must be received by 5th February 2021 or 8th March 2021 respectively.
These deadlines give us plenty of time to meet with you during the recruitment process and, if you’re successful, for us to apply for your visa.
