How does CSI (Comprehensive Sickness Insurance) relate to being lawfully resident?
CSI stands for Comprehensive Sickness Insurance and it is a requirement for certain people to have it to be considered lawfully resident in the UK.
EU citizens have been living in the UK under freedom of movement rules. These rules have allowed people of EU countries to live and work around the European Union.
To be able to live in another EU country, after an initial period of 3 months, EU citizens need to be a ‘qualified person’ under these freedom of movement rules to reside in the UK lawfully. The main categories are worker, self-employed, jobseeker, student or self-sufficient.
The latter two categories (student and self-sufficient) need to be financially self-sufficient and have this ‘CSI’ to exercise to be considered lawfully resident.
Note: this question, like other FAQs on Comprehensive Sickness Insurance (CSI), relates to applications for British citizenship, when considering whether periods of past residence were lawful.
