Before you travel please make sure to link your passport to your Evisa. You do not need to update your UKVI account every time you travel out of the UK, but you must ensure your UKVI account information is up to date before any travel, especially if your passport or other personal details have changed.
If your passport number, name, nationality, or any other personal information has changed since you last updated your UKVI account, you must update those details before travelling.
Not doing so could lead to delays or problems when re-entering the UK, such as being unable to prove your right to enter or experiencing issues with airlines and border control. You can find more information or update your details on the UKVI website.
For more information on travel during term time, please read the guidance on the travelling in and out of the UK webpage.
