Becoming a British citizen through Naturalization is how a foreign national can gain citizenship after fulfilling the UK government's criteria. Usually, adults who have resided in the UK for a period and have Indefinite Leave to Remain (ILR) or Settled Status under the EU Settlement Scheme take this route. Naturalization gives individuals complete citizenship rights, such as the ability to apply for a British passport, vote in UK elections, and reside and be employed in the UK without immigration limits.
To qualify, applicants generally need to have resided in the UK for at least five years (or three years if married to a British citizen) and have had ILR or Settled Status for a minimum of one year before applying. Besides residency, they also should meet the good character demand, prove English language skills, and pass the Life in the UK Test. Naturalization is the usual path for most adult applicants, unlike registration, which applies to children and some special situations. Once granted, British citizenship is permanent.
To apply for British Naturalization, you must meet certain requirements. You must:
Gaining British citizenship offers several lasting benefits, such as:
British citizenship applications vary with individual situations. Adult naturalization is standard for those over 18 meeting residency and legal standards, like having Indefinite Leave to Remain. Registration is for children born to British parents or those with citizenship rights through ancestry. Special cases exist for those from British Overseas Territories, Crown service, or with statuses like British Nationals (Overseas) from Hong Kong. Each path has criteria based on age, status, family, and background.
For adults, becoming a British citizen usually means going through naturalization. People 18 and older can apply if they've legally lived in the UK for at least five years. They also need to have Indefinite Leave to Remain or Settled Status for at least a year before applying.
If someone is married to a British citizen, they only need to have lived in the UK for three years. Plus, they don't have to wait a year after getting Indefinite Leave to Remain or Settled Status.
Individuals applying also need to pass the Life in the UK Test, show they know English, Welsh, or Scottish Gaelic, and prove they are of good character. Doing all this means they can become a full British citizen, get a British passport, and have all the same rights as any other UK national.
British citizenship registration, primarily for children, is a legal path based on entitlement, unlike discretionary naturalization. Eligibility often stems from birth, descent, or specific criteria. Children born in the UK to non-British parents could qualify if the parents later get citizenship or settled status. Children born abroad to British citizens may also be eligible under certain situations. Some adults with ties to former British territories or those who are stateless may register. Each route needs specific documents proving UK links or British parentage. Registration is usually simpler for those under 18 to become British citizens.
Individuals having ties to a British Overseas Territory might be able to get British citizenship if they meet specific criteria that recognize their past or legal ties to the UK. British Overseas Territories citizens (BOTCs) can apply to become British citizens, especially if they've lived in the UK for a while or have BOTC status through birth, ancestry, or naturalization. Other ways to apply exist for those who have worked for the Crown, were born to British mothers before 1983, or have older family ties that allow them to claim British nationality. Specific rules apply to groups like British Nationals from Hong Kong and those affected by nationality law changes. These applications need legal proof of eligibility based on history or family links to Britain or its past territories.

Becoming a British citizen involves a legal process called Naturalization, where an adult who isn't already British can gain citizenship if they meet specific requirements. This grants complete rights in the UK, such as the ability to vote, work, reside permanently, and get a British passport. Typically, people can apply after having Indefinite Leave to Remain (ILR) or Settled Status and living in the UK for a minimum of five years (or three years if married to a British citizen). Applicants need to show they are of good character, pass the Life in the UK test, meet certain residency rules, and meet an English language standard.

For British naturalization, most people need to pass a B1-level English speaking and listening test from a Home Office-approved center. Instead of a test, applicants can use a degree taught in English, citizenship from a majority English-speaking country, or being 65 or older to meet this requirement. If you don't meet the English standard, your application will be denied, so you need to have proper documentation.
To be eligible for British naturalization, you need to have resided in the UK for a minimum of 5 continuous years before your application. Within this period, absences from the UK should not exceed 450 days total, with no more than 90 days spent outside the country in the last year. A 12-month period holding Indefinite Leave to Remain (ILR) or Settled Status is also a requirement unless you’re married to a British citizen. If married to a British citizen, the residency requirement is reduced to 3 years, and you can apply for naturalization as soon as you get ILR or Settled Status.
An applicant can leave the UK while a UK Naturalisation citizenship application is being processed, provided you have kept the original passport. For the citizenship application, they should submit a fully certified copy of your passport and keep your original passport for travel purposes.
You can be eligible to apply for British citizenship after five years with UK settled status if you have an entire settled EU status or Indefinite Leave to Remain or become a British citizen through marriage. If you are married to a British citizen or a UK-settled person, you can apply to naturalize as a British citizen after three years of living in the UK and as soon as you are granted ILR, ILE, or EU-settled status.
The application fee for UK Naturalisation is £1,500.
