British Citizenship: Country-Specific Guides Hub
While the requirements for British citizenship are the same for everyone, each nationality brings specific considerations around dual citizenship, document requirements, and community support. This hub connects you to country-specific guidance.

In short
- The naturalisation requirements are the same for almost everyone, with a few named exceptions.
- Irish citizens have their own route: section 4AA, in force since 2025.
- Nationals of countries on the majority English-speaking list take no English test.
- Whether you keep your first nationality is decided by that country's law, not the UK's.
The naturalisation requirements barely vary by nationality, but the exceptions that do exist are worth knowing: a separate route for Irish citizens, an English test exemption for some countries, and a registration route for people who hold a lesser form of British nationality and nothing else. Whether you keep your first nationality is the other country's decision, not the UK's.

Where the Requirements Actually Differ
The naturalisation requirements — residence, absences, settlement, English, the Life in the UK test, good character — apply the same way to nationals of almost every country. The exceptions are specific and named in law:
- Irish citizens. Section 4AA of the British Nationality Act 1981, introduced by the British Nationality (Irish Citizens) Act 2024, is a registration route for an Irish citizen of any age who was in the UK at the start of a 5-year period ending with the application, was not absent for more than 450 days in it or 90 days in the final 12 months, has no immigration breaches in that period, and is of good character. The Home Office published its caseworker guidance for it on GOV.UK. The registration fee for an Irish citizen is lower than the naturalisation fee.
- Nationals of majority English-speaking countries do not have to pass an English test. The Home Office keeps a fixed list of those countries. A country having English as an official language does not put it on the list, so check the list itself rather than assuming — see our English language guide.
- Holders of another form of British nationality. British overseas citizens, British subjects, British protected persons and British nationals (overseas) who hold no other citizenship or nationality have an entitlement to register under section 4B. Our guide to the forms of British nationality sets out the conditions.
- Commonwealth citizens with a UK-born grandparent are eligible for the UK Ancestry visa. That is a visa, not a nationality claim: it leads to settlement, and then to naturalising in the ordinary way. See citizenship through grandparents.
Keeping Your First Nationality
The UK does not require you to give up another nationality, and becoming British does not, from the UK side, affect any other citizenship you hold. Our dual citizenship guide covers the UK position.
Whether you keep your first nationality is decided entirely by that country's own law, which the UK does not publish and Rowan does not attempt to summarise country by country. The rules differ sharply — some countries allow more than one nationality outright, some withdraw theirs automatically when you take another, some require you to notify them, and several have changed their position in recent years.
The authoritative source is the country itself: its embassy or high commission in the UK, or its own government's nationality department. A country's consulate can tell you what its current law is; nobody else can tell you reliably. Our guide on how British citizenship affects your other nationality covers the questions worth asking them.
Common Considerations
- Document availability: Some countries are slower to issue documents like police clearance certificates or birth certificates. Start gathering documents early.
- Name discrepancies: If your name appears differently on documents from different countries, address this in your application. See our name change guide.
- Translation: Documents not in English must be professionally translated. Use a certified translation service.
- Community support: Country-specific community organisations across the UK can provide advice, language support, and help with applications.

Questions and answers
Does my home country affect my British citizenship application?
Mostly not, but there are real exceptions. Irish citizens have their own registration route under section 4AA of the British Nationality Act 1981. Nationals of the countries on the Home Office's majority English-speaking list do not have to take an English test. British overseas citizens, British subjects, British protected persons and British nationals (overseas) who hold no other nationality have a registration route under section 4B. For everyone else the naturalisation requirements are the same, and your own country's rules on dual nationality are a separate question with its own answer.
Will I lose my original citizenship if I become British?
Not because of anything the UK does. The UK does not require you to give up another nationality. Whether your first country lets you keep its citizenship is decided by that country's own law, and the rules differ sharply and change. Ask that country's embassy or high commission in the UK.
Are there special routes for Commonwealth citizens?
There is no shorter citizenship route for Commonwealth citizens as such. What Commonwealth citizenship can open is the UK Ancestry visa, for those with a grandparent born in the UK, the Channel Islands or the Isle of Man, or before 31 March 1922 in what is now Ireland, or on a UK-registered ship or aircraft. Separately, a qualifying Commonwealth citizen — one with permission to stay, or who does not need it — can register to vote in UK parliamentary elections, which is a voting rule rather than a nationality one.
Do I need to inform my home country when I become British?
That is a question for that country, not for the UK. Some countries require notification or registration of a new nationality, and some withdraw their own citizenship automatically. The country's embassy or high commission in the UK is the authoritative source.

It is not advice about an individual application under s.82 Immigration and Asylum Act 1999, and Rowan is not regulated by the Immigration Advice Authority. Immigration rules change several times a year. For advice on a particular situation, contact an adviser authorised by the Immigration Advice Authority or an immigration solicitor.
