Extend your visa
You may be able to apply to extend your stay in the UK under a Tier 4 (Child) visa.
You must:
- meet the eligibility requirements of this visa
- already be in the UK
- be sponsored by an independent school
When to apply
You must apply:
- within 6 months of getting a confirmation of acceptance for studies (CAS)
- before your current visa expires - but no more than 3 months before the course start date on your CAS
You can stay in the UK until you get your decision.
Ways to apply
If you want to get a decision more quickly than the standard 8 weeks, you can apply for priority service - there’s a limited number of places each day.
| Application type | Time for a decision | Cost per person |
|---|---|---|
| Standard | 8 weeks | £475 |
| Priority | 10 days | £952 |
You’ll also need to provide biometric information and pay the healthcare surcharge.
Apply for the standard service
You can apply online for the standard service.
Pay the appropriate fee at the same time.
Apply for the priority service
You must fill in a request form before you can use the priority service. Send it to the email address on the form.
Only the first 60 requests received each day after 8:30am (Monday to Friday) are accepted - you’ll get an email saying if you’ve been successful.
Once you’ve been accepted for the priority service you should apply online within 24 hours. Pay the fee at the same time.
Send your supporting documents by registered post or courier to the address given in the priority service acceptance email.
Make sure your documents get there within 2 days of when you apply.
Provide your biometric information
You must also pay £19.20 to have your biometric information (fingerprints and a photo) taken. You’ll be told how to do this after you’ve applied. You’ll have to do it within 2 working days if you’re using the priority service.
You’ll get a biometric residence permit if your application to extend your visa is successful.
Pay the healthcare surcharge
You must also pay the healthcare surcharge.
Check how much you’ll have to pay before you apply for your extension.
What happens next
You’ll be contacted if your application is complex and will take longer, for example because:
- your supporting documents need to be verified
- you need to attend an interview
- of your personal circumstances (for example if you have a criminal conviction)
