Common questions about British citizenship
How long after settlement can you apply for British citizenship?
Most applicants wait 12 months after being granted Indefinite Leave to Remain before naturalising. The exception is the spouse or civil partner of a British citizen, who can apply as soon as they hold settled status, provided the residence requirement is met.
What are the main requirements to naturalise as British?
An adult applicant needs settled status, a qualifying period of UK residence, good character, and passes in the Life in the UK Test and the English language requirement. The residence period is generally five years, or three years for the spouse of a British citizen. Children usually apply by registration rather than naturalisation.
Can you hold British citizenship alongside another nationality?
The UK permits dual and multiple nationality, so becoming British does not by itself require giving up another citizenship. Whether the other country allows its citizens to hold a second nationality is a matter for that country's law, and should be checked before applying.
