It is now possible to apply for Tier 4 (Child) or Tier 4 (General) student immigration permission in the UK using a faster priority service. The Home Office aims to make a decision within 10 days.
Before you make your online application, you must complete and submit a Tier 4 priority request form. Only the first 60 applications received each day can use this service.
If you are successful, the Home Office will send you an email to let you know and you should then make your online application within 24 hours. The fee is £823. Your documents must arrive with the Home Office no later than two days after you apply.
Before you apply, make sure you read the Home Office's full information for Tier 4 (General) student applicants and for Tier 4 (Child) student applicants.
