Hi thank you for your question. Please remember to RATE my answer OK SERVICE, GOOD SERVICE OR EXCELLENT SERVICE so I can get credited for my time.
You do not need to get the UKBA's permission if you want to do a different course of study with your Tier 4 sponsor and the new course will finish before your current permission to stay expires. Your Tier 4 sponsor will tell the UKBA that you have changed course.
If your new course will end before your permission to stay expires, you must tell the UKBA by sending an email message to [email protected].
If your new course will end after your current permission to stay expires, you will need to make a new Tier 4 application to the UKBA. You will therefore need a new confirmation of acceptance for studies from your Tier 4 sponsor.
You can make this new application at any time before your current permission to stay expires, but I recommend that you do this as soon as possible.
The UKBA usually inform you by letter if your visa has been curtailed but I suggest you do the above and inform your Tier 4 Sponsor to inform the UKBA of your change of course, or if your leave to remain expires before your course ends, send them an email.
I hope this answers your question, if so kindly rate my answer positively so I can get credited for my time.
