Recent developments will likely affect many areas including nationality, naturalisation, registration, access to benefits and more. The answer given below is therefore now out of date.

In the meantime, if you believe you are affected, please seek legal advice. If you have suffered loss because of past decisions where the Home Office said you did not meet the CSI requirement, please email us at .


If you are applying for British citizenship and you have short gaps (as a student or self-sufficient person) without CSI, this may not be a problem.

Realistically, you would support your application with evidence which is spaced out over the months of each year, rather than covering every single 2 week period, so such a short gap would not even feature. 

If you had a short gap without CSI when you were a student before obtaining CSI, it might be worth explaining the reason for that and asking for discretion for the gap. If your short gap is during a work period, this generally is not a problem as your work evidence should cover longer periods of time.

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.

CSI is not required to apply for pre-settled or settled status under the EU Settlement Scheme. Also, once pre-settled or settled status is granted, you are lawfully resident, and you do not need CSI.
