Case Study of a Family That Successfully Moved from Hong Kong to the UK Under the BNO Route

The number of Hong Kong residents applying for British National (Overseas) (BNO) visas surged past 200,000 total applications by early 2025, according to data published by the UK Home Office in its quarterly immigration statistics for Q1 2025. The BNO route, opened in January 2021, allows eligible Hong Kong BN(O) status holders and their dependants to live, work, and study in the United Kingdom. The pathway to Indefinite Leave to Remain (ILR) requires five years of continuous residence, followed by a further twelve months before an application for British citizenship can be made. For families planning this move, the process involves not only visa compliance but also practical relocation steps—school enrolment, housing, employment, and tax registration. This case study follows the fictional “Chan family,” a four-person household comprising two parents and two school-aged children, who completed their relocation to the UK under the BNO route between 2022 and 2024. The account is based on publicly available UK Home Office guidance and standard procedural timelines. The names and specific circumstances are illustrative only.

The Application Timeline and Key Deadlines

Step 1: Eligibility Verification and Document Collection

The Chan family’s process began in March 2022. The father, Mr. Chan, held a valid BN(O) passport issued before the 1997 handover. The mother, Mrs. Chan, was a Hong Kong permanent resident without BN(O) status. Their two children, aged 10 and 13, held Hong Kong permanent identity cards.

The UK Home Office requires the primary applicant—the BN(O) status holder—to submit the main application. Dependants (spouse and children under 18) apply on the same form. The legislation governing this route is the Immigration Rules, Part 7A, introduced by Statement of Changes in Immigration Rules HC 813 (October 2020). The key documentary requirements included: valid BN(O) passport, Hong Kong permanent identity card, proof of address in Hong Kong for the three years preceding the application, and tuberculosis test results for all applicants over 11 years old.

The Chan family prepared certified translations of all Hong Kong documents. The UK Home Office accepts documents in English or Welsh; any document in Chinese requires a certified translation. The family used a translation service accredited by the Hong Kong Institute of Translators.

Step 2: Online Application and Biometric Appointment

The family submitted their online application on 1 June 2022. The application fee for a family of four was £2,404 (primary applicant £1,208, each dependant £398). The Immigration Health Surcharge (IHS) was paid separately: £3,120 per adult for five years and £2,340 per child, totalling £10,920.

The biometric appointment was booked at the Hong Kong Visa Application Centre (VAC) in Admiralty. The appointment occurred on 10 June 2022. The UK Home Office processed the application within 12 weeks. The decision email arrived on 1 September 2022—all four applicants received approval.

Step 3: Entry Clearance and Travel

Entry clearance vignettes were issued in the family’s passports. The vignettes were valid for 90 days from the date of issue. The family booked flights for 15 October 2022. The UK Border Force at Heathrow Airport checked the vignettes and stamped the passports. The date of entry—15 October 2022—became the start date for the five-year ILR clock.

Housing and School Enrolment

Housing Strategy: Short-Term Rental Followed by Long-Term Lease

The Chan family used a short-term serviced apartment in Manchester for the first six weeks. The UK Home Office requires proof of accommodation for the visa application, but does not specify a minimum rental period. The family provided a booking confirmation for the serviced apartment as their initial accommodation evidence.

In November 2022, the family signed a 12-month assured shorthold tenancy (AST) for a three-bedroom flat in Sale, Greater Manchester. The monthly rent was £1,450. The tenancy agreement was registered with the Tenancy Deposit Scheme (TDS) as required by the Housing Act 2004. The family provided copies of the tenancy agreement and utility bills to the UK Home Office as part of their ongoing residence evidence.

School Placement: State School Admission Process

The children were enrolled in a local state primary school (Year 6) and a state secondary school (Year 9). The UK Department for Education’s School Admissions Code (2021) governs admission procedures. The family applied through the Trafford Council school admissions portal.

The primary school required proof of address, the child’s Hong Kong birth certificate, and immunisation records. The secondary school conducted a standard admissions interview. Both children started school on 31 October 2022, two weeks after arrival. The schools provided English as an Additional Language (EAL) support under the school’s EAL policy.

Employment and Tax Registration

Job Search and Employment Contracts

Mr. Chan, a chartered accountant with 15 years of experience, began job applications in September 2022, before travel. He secured a position as a financial controller at a Manchester-based manufacturing firm. The start date was 1 November 2022. His employment contract was governed by the Employment Rights Act 1996.

Mrs. Chan, a secondary school teacher, obtained Qualified Teacher Status (QTS) through the UK Department for Education’s international recognition process. She submitted her Hong Kong teaching qualifications via the Teacher Services portal in October 2022. QTS was granted in December 2022. She began supply teaching in January 2023, and secured a permanent post at a local academy in April 2023.

National Insurance Number and Tax Registration

Both adults applied for National Insurance (NI) numbers immediately after arrival. The application was made via the Department for Work and Pensions (DWP) online portal. NI numbers were issued within three weeks. HMRC registration for tax purposes was automatic upon employment. The family registered for the Marriage Allowance tax benefit, transferring £1,260 of Mr. Chan’s personal allowance to Mrs. Chan for the 2022/23 tax year.

Citizenship Application Pathway

ILR Application: The Five-Year Clock

The Chan family’s five-year continuous residence period began on 15 October 2022. The UK Home Office requires applicants to have spent no more than 180 days outside the UK in any 12-month period during those five years. The family kept a travel log and avoided any trips exceeding 10 days per year.

The ILR application is submitted online using the “Set (O)” form. The fee as of 2024 is £2,885 per person. The family will submit their ILR applications in October 2027, after completing five full years of residence.

British Citizenship: The Twelve-Month Wait

After ILR is granted, the family must wait 12 months before applying for British citizenship. The citizenship application uses the “AN” form. The fee as of 2024 is £1,580 per adult and £1,012 per child. The Life in the UK test must be passed by each adult applicant. The test is administered by the Home Office and costs £50 per attempt.

The family enrolled in a Life in the UK preparation course run by a local further education college. Mr. and Mrs. Chan passed the test on their first attempt in January 2028. The citizenship application is expected to be submitted in November 2028, with a decision within six months.

Key Takeaways for BNO Route Applicants

1. The BNO visa application requires the primary applicant to hold valid BN(O) status; dependants without BN(O) status can apply on the same form if they meet the relationship and dependency criteria.
2. The five-year ILR clock starts on the date of entry into the UK, not the date of visa issue—plan travel to maximise the residence period.
3. School placement in state schools is governed by the School Admissions Code 2021; apply through the local authority portal as soon as you have a confirmed address.
4. Employment rights under the Employment Rights Act 1996 apply from day one of employment; ensure your employment contract complies with minimum wage and working time regulations.
5. The Life in the UK test must be passed before applying for citizenship; book the test at least six months before your planned application date to allow for retakes if necessary.
