The EU Settlement Scheme (EUSS) opened to EU, EEA and Swiss citizens and their eligible family members following Brexit. The aim was to grant permission to protect residency in the UK and therefore the right to study, work, and live within the UK after the post-Brexit transition and grace periods ended.
The test for qualifying was whether the individual was resident in the UK before 11pm on 31 December 2020 but the grace period allowed applications to be made up to the end of 30 June 2021. Millions of applications were made in that time frame and the vast majority have been successful.
The application is free and simple and can be completed using a suitable mobile phone.
