If you are studying a longer course at Cambridge, you may find that your Biometric Residence Permit (BRP) does not cover the full length of your visa. This is because BRPs are currently only being issued with a validity until 31 December 2024, even if your course and immigration permission continue after this date. From 1 January 2025, UK Visas and Immigration (UKVI) intend for immigration permission to be evidenced as an online status and without a BRP. UKVI has advised that they will provide updated guidance in relation to this in early 2024. If this is relevant to your circumstances, you do not need to do anything and your immigration status will not be affected.
