British Citizenship for Hong Kong BN(O) Holders

What the Status Is, and What the Visa Is

British national (overseas) is a form of British nationality acquired by registration before 1 July 1997 by people connected to Hong Kong. It cannot be acquired now, and it is not passed to children. On its own it does not carry the right to live in the UK.

The British National (Overseas) visa, opened on 31 January 2021, is what gives that right. It is an immigration route, and it leads to settlement and then to naturalising in the ordinary way.

Who Can Apply

GOV.UK says you can apply if you are 18 or older and are either:

• a British national (overseas), or
• the child of a British national (overseas) born on or after 1 July 1979

The second limb is the one that has widened, and older articles still describe a narrower household-member route. An adult child in this position applies separately from their parent, and can bring their own family members with them.

Your permanent home must be:

• in Hong Kong, if you are applying from outside the UK; or
• in the UK, the Channel Islands, the Isle of Man or Hong Kong, if you are applying from inside the UK.

On a first application you must show you have enough money to support yourself and your family members for at least 6 months in the UK. GOV.UK says an offer of work does not usually count as evidence of this, unless you are transferring to a UK job with your current employer. You may also need a tuberculosis test certificate, depending on where you apply from.

Family Members

Family members apply for their own visas. They must usually apply at the same time as you, except a partner, a child under 18, or an adult dependent relative, who may apply later. If the main application is refused, the family applications are refused too.

Length, Fees and Conditions

You choose the length of the first grant:

• 2 years and 6 months — the visa fee is £206 per person
• 5 years — the visa fee is £285 per person

The immigration health surcharge is charged separately and is the larger cost. For each adult it is £2,587.50 over 2 years 6 months or £5,175 over 5 years; for each child under 18, £1,940 or £3,880. You can extend the visa as many times as you want.

On this visa you can:

• work — with one exception: not as a professional sportsperson or sports coach
• study, including at school, college or university

You cannot usually claim public funds. GOV.UK sets out financial circumstances in which access to benefits can be granted — having nowhere to live and being unable to afford it, being unable to afford essential living costs such as food or heating, being at risk of either, or having a very low income where the lack of benefits would harm a child's wellbeing. It states plainly that getting access to benefits does not stop you applying to settle after 5 years. Our guide to no recourse to public funds covers what counts as a public fund.

A decision usually takes 12 weeks from the date of application, or from the date you gave your fingerprints if you attended an appointment rather than using the identity app.

The Healthcare Surcharge Is Not Free Healthcare

Paying the surcharge lets you use the National Health Service on the same basis as someone who lives here. GOV.UK is explicit that you will still need to pay for some NHS care, such as prescriptions, dental care and eye tests. Those charges differ across the UK: prescriptions are free in Scotland, Wales and Northern Ireland, and charged in England.

Settlement After 5 Years

You can apply for settlement (indefinite leave to remain) after 5 continuous years in the UK, and the earliest application is 28 days before the 5 years are complete. The published conditions are:

• in most cases, no more than 180 days outside the UK in any 12-month period
• if you are aged 18 to 64, passing the Life in the UK test and meeting the English requirement at level B1 in speaking and listening, or holding a degree taught or researched in English — with published exemptions from each

Time on an earlier UK visa can count towards the 5 years if that visa was one that leads to settlement and your last visa was the BN(O) one. GOV.UK gives Skilled Worker, Family, Global Talent, UK Ancestry and others as examples. Time on a Student visa or the Youth Mobility Scheme does not count, and neither does time on permission granted outside the rules at the border.

Settlement costs £3,226 for each person applying and a decision usually takes 6 months. GOV.UK warns that you must not travel outside the UK, Ireland, the Channel Islands or the Isle of Man until you have the decision, because the application will be withdrawn if you do. If settlement is refused, the visa may be extended for 30 months instead.

Note the English level: B1 at settlement. An increase to B2 from 26 March 2027 has been announced for several settlement routes named in the March 2026 statement of changes, so check whether it reaches this one before relying on B1 for an application after that date. Our guide to the B2 change sets out what was announced.

Citizenship After Settlement

GOV.UK says a British national (overseas) can usually apply for British citizenship 1 year after settling. That is the ordinary naturalisation rule rather than a special one: the applicant must have been free of any immigration time restriction for the 12 months ending with the application. The other requirements apply as normal:

• in the UK on the day exactly 5 years before the application, and no more than 450 days outside it in those 5 years or 90 days in the final 12 — see our absences guide
• the good character requirement
• the Life in the UK test and English at B1, which will already have been met at settlement — a Life in the UK pass does not expire
• the fee, currently £1,709 plus a £130 ceremony fee. Our costs guide has the breakdown

The spouse or civil partner of a British citizen applies on the 3-year route instead, with no 12-month wait after settlement. Our naturalisation guide covers both.

Children

A child born outside the UK who came here with you is registered as a British citizen on form MN1 rather than naturalising. A child born in the UK while you were not settled may have their own route to registration. Neither happens automatically.

Section 4B: A Different Route Entirely

Separately from the visa, section 4B of the British Nationality Act 1981 gives an entitlement to register as a British citizen to a British national (overseas) who holds no other citizenship or nationality at all, and who has not, since 19 March 2009, renounced, voluntarily relinquished or lost through action or inaction any citizenship or nationality. British nationals (overseas) were brought within section 4B on 13 January 2010.

This reaches a small group — most British nationals (overseas) also hold Chinese nationality — and giving up another nationality in order to qualify does not work, because doing so is itself a bar. Our guide to the forms of British nationality sets out the conditions in full.

Two Things to Check With the Right Authority

• How your other nationality is affected. The UK does not require you to give up any other nationality and does not publish other countries' rules. How the Chinese and Hong Kong authorities treat British national (overseas) status, and what acquiring British citizenship means for a person's position with them, is a question for those authorities. Our guide on the effect on your other nationality sets out what to ask.
• Professional qualifications. Whether a Hong Kong qualification is recognised for practice in the UK is decided by the relevant UK regulator for that profession, not by the Home Office, and the answer differs by profession.

GOV.UK also publishes a Welcome Programme for British National (Overseas) visa holders in the UK, which sets out the support available. Our guide to choosing where to live covers the practical side, and our settlement requirements guide covers the stage before citizenship.
