Biometric Residence Permits (BRPs) are being phased out by UK Visa and Immigration (UKVI) and replaced by a digital immigration status known as the eVisa. An eVisa is your visa status viewable online, and it's replacing physical visa documents like BRPs.
If you have a BRP that expires on 31 December 2024, but your overall permission to stay in the UK is longer, then you'll have the remainder of your immigration permission shown on your eVisa. This change means that visa holders will need to register an account with UKVI.
To set up your eVisa, you must take action before your BRP expires.
