BN(O) Visa to ILR 2026: 5-Year Settlement Timeline for Hong Kong

Overview: the BN(O) visa route to settlement

The British National (Overseas) visa — usually written BN(O) visa — opened on 31 January 2021 for Hong Kong residents with BN(O) status and their close family members. It gives the right to live, work, and study in the UK and, critically, a clear path to indefinite leave to remain (ILR) after 5 years of continuous residence, followed by British citizenship 12 months later.

Because the route opened in early 2021, the first wave of BN(O) holders reached the 5-year mark in 2026. If you arrived in the first year of the scheme, you are likely eligible to apply for settlement now. This guide covers exactly what ILR requires, the absence rules that most often catch people out, the tests, the documents, and the full cost.

The rules are set out in the GOV.UK BN(O) visa guidance. Always check the latest official guidance or consult an immigration adviser for your specific situation.

Eligibility requirements for ILR

To qualify for indefinite leave to remain as a BN(O) visa holder, you must:

• Have completed 5 years of continuous residence in the UK on the BN(O) route.
• Not have been absent for more than 180 days in any rolling 12-month period.
• Pass the Life in the UK test.
• Meet the English language requirement at level B1 or above (unless exempt).
• Not fall foul of the general grounds for refusal (e.g. serious criminality).

There is no minimum salary, no sponsor, and no financial threshold — one of the key differences from work routes like Skilled Worker.

The 5-year route (and the 2.5-year option)

BN(O) visas are usually granted for either 5 years in one go, or 2 years and 6 months at a time (which you then extend). Either way, the settlement clock is the same: you need 5 years of continuous residence before you can apply for ILR. If you chose the shorter grant, you simply extend before it expires so your residence is unbroken.

Timeline: BN(O) visa to ILR to citizenship

• Year 0: Arrive in the UK on the BN(O) visa; your continuous-residence clock starts.
• Year 5 (minus 28 days): Earliest date you can apply for indefinite leave to remain.
• ILR + 12 months: Earliest date you can apply for British citizenship (naturalisation), provided you meet the residence and absence rules for citizenship.

You can track your exact ILR and citizenship dates — accounting for every trip — with the ILR eligibility calculator.

Absence rules

The single most important rule for BN(O) settlement is the absence limit: you must not spend more than 180 days outside the UK in any rolling 12-month period during the 5-year qualifying period. This is assessed on a rolling basis, not per calendar year, so a long trip that straddles two years can still breach the limit. Use the absence calculator to check every window.

English language requirement

At the ILR stage you must demonstrate English at CEFR level B1 or above, usually through an approved Secure English Language Test (SELT), a degree taught in English, or by being a national of a majority-English-speaking country. Many BN(O) applicants satisfy this through prior qualifications; check whether your evidence is accepted before booking a test.

Life in the UK test

You must pass the Life in the UK test — 24 multiple-choice questions in 45 minutes, pass mark 75% (18 correct). It costs £50 and can be retaken as many times as needed. You can prepare with the free Life in the UK practice tests.

Required documents

• Current passport and BRP, plus your BN(O) passport or Home Office confirmation of BN(O) status (an expired BN(O) passport is still accepted as proof of status).
• Evidence of 5 years continuous residence — tenancy agreements, council tax, utility bills, bank statements, employer or study letters, spread across each year.
• Life in the UK test pass certificate.
• English language evidence (test certificate, degree, or nationality).
• Travel history / dates of absence for the qualifying period.

Costs breakdown

The IHS is the largest ongoing cost — over 5 years that is £5,175 per person. Estimate your full journey with the UK visa cost calculator.

Dependants

Family members on your BN(O) visa (partner and children) follow the same 5-year qualifying period and the same absence, test, and language rules, each applying for ILR in their own right. Each dependant pays their own IHS and application fees.
