The British Home Office is urging holders of biometric residence permits (BRP), biometric residence cards (BRC) and passports with a sticker or stamp granting residence to create accounts in the electronic visa system.
More than six million European immigrants who are part of the European Union Citizen Registration Scheme [EUSS] opened after Brexit are already subject to this policy.
While a card or paper can be lost, stolen or tampered with, an electronic visa allows visa holders to instantly and securely prove their residency rights, the Home Office explains.
This is done via a webpage, after entering their identity document number and answering several security questions.
From next year, immigrants will simply need to present their passport when entering the UK, which will be cross-referenced with information about their residence status to be granted entry.
The eVisa is also used for employment, study or housing rental purposes, access to the public health system or to receive social benefits.
However, immigrant support organisations such as 3 million have highlighted the weaknesses of the digital system and the lack of literacy of many of these immigrants in using electronic means as problems.
To facilitate the transition, the Home Office has made up to four million pounds (4.8 million euros) available to fund the work of these organisations.
This process is taking place as part of the digitalisation of the UK's borders.
Last week, the Government announced that European tourists will need an Electronic Travel Authorisation from April 2025 to enter the country.
