A. Recent Proposals Affecting the Route to Citizenship
Proposals in 2025 would lengthen the usual qualifying period for settlement from five to ten years for many routes, delaying when people can apply for citizenship. The trend is toward a contribution‑based pathway. Current rules still apply until changes take effect.
B. Ways People Become British Citizens
Citizenship may be acquired by naturalisation, birth, descent, marriage/civil partnership, or registration.

1) Naturalisation (most common)
Applicants must be 18+, meet residence limits, show English ability, pass the Life in the UK Test, and meet the good character requirement. Those married to a British citizen may apply as soon as they have settled status; others usually need to hold it for 12 months first.

2) Citizenship by Birth
Automatic citizenship at birth depends on a parent being British or settled at the time of birth. Children may later register if a parent becomes British/settled or if the child meets the age‑10 residence rule.

3) Citizenship by Descent
Those born abroad to a British parent may be British by descent, but this normally does not pass automatically to children born overseas, subject to limited exceptions.

4) Citizenship via Marriage/Civil Partnership
Spouses/civil partners of British citizens can apply after three years’ residence and must hold settled status on the application date, as well as meet language, Life in the UK, and good character requirements.

5) Registration Routes
Some adults and many children qualify to register, including UK‑born children who lived in the UK until age 10 or where a parent became British/settled after the child’s birth.

C. Eligibility Checklist (at a glance)

  • Age 18+.
  • Residence: normally 5 years (3 if married to a British citizen), within absence limits.
  • Status: settled status held; usually 12 months unless applying as a spouse.
  • English: degree taught in English or approved SELT (unless exempt).
  • Life in the UK Test: pass required (unless already used for settlement).
