British citizenship

Am I eligible for British citizenship?

Written by Bill Zahr  |  Noble Rose Immigration Service  |  IAA Regulated Level 1  |  Last updated June 2026

Overview

British citizenship by naturalisation under Section 6 of the British Nationality Act 1981 is the highest form of immigration status in the United Kingdom. It provides absolute protection from deportation, the right to a British passport, and the right to vote in all UK elections. This page sets out the eligibility requirements for the two naturalisation routes, Section 6(1) for ILR holders and Section 6(2) for spouses of British citizens and the key registration routes for children.

What you need to know

Section 6(1) vs Section 6(2): which route applies

Section 6(1) is the standard naturalisation route for ILR holders who are not married to a British citizen requiring 5 years of qualifying residence and 12 months of holding ILR before application. Section 6(2) applies to spouses and civil partners of British citizens — requiring only 3 years of qualifying residence and permitting an application as soon as ILR is granted with no 12-month waiting period. The absence limits also differ: 450 days maximum across 5 years for Section 6(1) versus 270 days across 3 years for Section 6(2). In both cases absences in the final 12 months must not exceed 90 days.

The physical presence test: a common trap

The applicant must have been physically present in the United Kingdom on the exact day that falls 5 years (Section 6(1)) or 3 years (Section 6(2)) before the application submission date. If the applicant was travelling on that specific date even arriving back the same evening, they may fail this test. The date of application is the date the online form is submitted and payment is made, not the date of the biometric appointment.

The illegal entry bar: February 2025 update

From 10 February 2025, Home Office guidance states that applications will normally be refused where the applicant previously entered the UK illegally, regardless of how long ago the illegal entry occurred. The previous 10-year buffer has been effectively removed. Arguments based on Article 31 of the Refugee Convention (for refugees coming directly from territories where their life was at risk) or trafficking victim status may still succeed but require detailed legal submissions.

British citizenship for children

Children have separate registration routes under the British Nationality Act 1981. Section 1(3) entitles a child born in the UK to register once a parent obtains ILR or Settled Status. Section 1(4) entitles a child born in the UK who has lived here continuously for 10 years to register regardless of parental status. Section 3(5) provides a residence route for children born abroad to British by descent parents. The child registration fee was reduced from £1,214 to £1,000 from 8 April 2026.
