You should plan to leave the UK or make an application to extend/switch your visa before your visa expiry date. If you stay in the UK after your visa has expired and you have not made a new application, you will be classed as an ‘overstayer’. You will not have legal permission to be in the UK, which means that you will not be allowed to study or work, and you may not be able to access other services, such as healthcare. You will also not be allowed to have a bank account. If you are living in private rented accommodation, your landlord must report this to the Home Office, which may result in action being taken against you.
You are also liable to be removed from the UK by the Home Office.
If you stay in the UK for longer than 30 days after your visa has expired, you will not be allowed to make an application to return to the UK for at least one year after you leave.
Students often wrongly believe there is a ‘14-day grace period’. There is no grace period. Although you are permitted to make an application up to 14 days after your visa has expired, you will still be classed as an ‘overstayer’ with no legal permission to be in the UK until you have received a positive decision about your application.
Once you have left the University you should provide the Student Immigration Team (Compliance) of evidence to show that you either transferred to/studying at a different UK institution, switched to another immigration category or that you have returned to your home country. This will show as evidence to the Home Office that the University is no longer acting as your Student Sponsor.
