If you are thinking about applying for a British citizenship through naturalisation, it is important to understand the requirements before you apply. Taking the time to prepare can help you avoid delays, or a refused application.
Living in the UK
You must have lived in the UK for at least 5 years, or 3 years if you are married to or in a civil partnership with a British citizen.
You should also check that you have not spent too much time outside the UK during this period.
Immigration status
In most cases, you will need to hold indefinite leave to remain, settled status, or another form of permanent immigration status.
If you are not married to a British citizen, you normally need to have held this status for at least 12 months before applying.
Language skills and Life in the UK Test
As part of your application, you must show that you have sufficient knowledge of English, Welsh, or Scottish Gaelic, unless you qualify for an exemption.
You will also normally need to pass the Life in the UK Test, which assesses your knowledge of British history, culture, and society.
Good character Requirement
The Home Office will check whether you meet the "good character" requirement. This means they may look at:
Your criminal record
Your immigration history
How you have managed your finances
Whether you have followed UK laws
It is important to answer all questions honestly and provide correct information.
Your EUSS Settled Status already gives you the right to live and work in the UK. However, becoming a British citizen gives you some extra benefits:
A British Passport
A British passport can make international travel easier and provides permanent proof of your right to live and work in the UK.
Freedom to Live Abroad
Settled Status can be lost if you spend more than 5 years in a row outside the UK. British citizens can leave and return to the UK at any time without losing their status.
Full Voting Rights
British citizens can vote in all UK elections and can stand for public office.
Greater long-term certainty
Citizenship provides lifelong security and is not affected by future changes to UK immigration rules.
Citizenship for Future Children
Children born after you become a British citizen will automatically be British citizens from birth, even if they are born outside the UK.
