Overview
No place outside the Commonwealth has a closer or more complicated relationship with Britain than Hong Kong. A century and a half of British administration left institutions, a legal system and a language in common, and the connection has intensified rather than faded since 1997 — particularly following the introduction of the British National (Overseas) visa route in 2021, which brought a very large number of Hong Kong families to the UK.
Since January 2025 travel to Britain has required an Electronic Travel Authorisation for those using a Hong Kong SAR passport. Hong Kong remains a non-visa territory for UK purposes and nothing about what SAR passport holders may do in Britain has changed — the ETA is a digital pre-travel permission applied for online and attached to the passport number.
The essential thing to establish before anything else is which document you will travel on. Hong Kong SAR passport holders need an ETA. British National (Overseas) passport holders do not — the BNO passport is a British travel document, and its holders either travel as British nationals or use the BNO visa route, neither of which involves an ETA. Getting this distinction right is the single most important step for any Hong Kong traveller.
At a glance
Eligibility
If you travel on a Hong Kong SAR passport, you do not need a visa but you do need an ETA. Hong Kong is a non-visa territory for UK purposes, so SAR passport holders travel to Britain as visitors for tourism, family visits, business, conferences or short courses without a consular application. The ETA precedes that permission and does not reduce it — the six months Hong Kong visitors have always been allowed is unchanged.
If you travel on a British National (Overseas) passport, you do not need an ETA. The BNO passport is a British travel document and its holders are British nationals, so the ETA scheme does not apply to them. BNO status holders who have moved to the UK under the BNO visa route hold leave to remain, which carries its own permission to travel. This is the distinction that matters most on this page, and it is worth confirming which passport you will present before applying for anything.
Every traveller using an SAR passport needs their own ETA, at any age. Children and infants need one linked to their own passport and cannot be added to a parent's application. Mixed families are common in Hong Kong — some members on BNO passports, some on SAR passports — and each person's requirement follows the document they will actually travel on.
Hong Kong SAR passport holders are not in the ePassport gate cohort and will be seen by a Border Force officer at a staffed desk on arrival. BNO passport holders, as British nationals, use the British and Irish lane. Families travelling on a mix of documents should expect to be separated at the border and plan accordingly.
Stay & validity
An approved ETA is valid for two years from the date it is granted, or until your Hong Kong SAR passport expires, whichever comes first. Within that window there is no limit on entries, and each visit can last up to six months. For the many Hong Kong families with relatives now living in Britain, one application covering two years of visits is a genuine simplification.
The passport-expiry rule is the one to check first. The ETA is bound to the passport number you enter and ends when that document does. Hong Kong SAR passports are issued for ten years for adults and five for children under sixteen, so families applying together may find the children's authorisations expiring well before the parents'. Renewal does not transfer the ETA and there is no refund.
Britain does not require six months of onward passport validity, only that the passport covers your stay. Hong Kong travellers are used to stricter requirements across Asia and sometimes over-prepare, which is harmless — but the British rule is simply that the document remains valid while you are there.
Six months per visit is the maximum for a single entry rather than an annual allowance, and this matters more in Hong Kong than in most markets. Families visiting relatives who have settled in Britain sometimes stay for extended periods, and Border Force considers entries cumulatively. Repeated long stays that account for most of the year read as residence rather than visiting — where that is the real intention, the BNO route or another visa is the appropriate conversation.

Requirements
Everything Hong Kong SAR passport holders need before starting an application. The first five items apply to every applicant; the rest are specific to your nationality.
Passport bio-data page — a clear colour scan or photo showing your photograph, full name, date of birth, passport number and expiry date
Recent digital photograph — full face visible against a plain background, taken within the last six months, with no headwear other than for religious or medical reasons
A valid email address, which is where the approval is sent and which you should keep accessible while travelling
A credit or debit card to pay the Home Office ETA fee and our service fee together
Your travel and accommodation details — Border Force can ask about the purpose of your visit and where you are staying
Simple process
Four steps, entirely online, with our team checking every field before anything reaches the Home Office.
Enter your passport details exactly as printed, answer the suitability questions and upload your photograph. Most applicants finish in under ten minutes.
Our team checks your photo, passport number, name spelling and declarations against Home Office requirements before anything is submitted.
Your application goes to UK Visas and Immigration with the government fee paid, and we track its status until a decision is issued.
There is no sticker, label or document to print. The authorisation is held digitally against your passport number, and we explain exactly what to show at check-in.
Applications from Hong Kong are decided automatically in the great majority of cases, and most applicants receive approval within minutes. The Home Office asks travellers to allow up to three working days, and a small proportion are referred for manual review, usually where a photograph fails the automated check.
Apply at least a week before travelling. The buffer exists so that a mistyped passport number or a rejected photograph can be corrected without a second payment, not because the decision itself is slow.
The most valuable thing you can do early is establish the correct route for every member of a travelling party. Mixed families — some on BNO passports, some on SAR passports, some already holding leave to remain under the BNO visa route — are common, and applying for an ETA that is not needed, or failing to apply for one that is, are both avoidable with a single check at the planning stage.
On arrival
An approved ETA gets you on the plane. This is what happens once you land, and how to make the arrival as quick as possible.
Your nationality is not currently in the ePassport gate cohort, so you join the queue for a staffed desk on arrival. Your ETA is exactly the same document and carries exactly the same permission — only the arrival process differs.
The officer may ask where you are staying, how long you intend to remain and how the trip is funded. Having your hotel booking, return ticket and, if you are visiting family, their address to hand makes this a thirty-second conversation.
Desk queues at Heathrow can be long at peak arrival banks, particularly early morning. If you are connecting onward to a domestic or European flight, allow more than the airline's minimum connection time.
Unlike the automated gates, a staffed desk stamps your passport with the date of entry. That stamp is your evidence of when your six-month permission began, so do not let it be obscured or removed.
Getting there
Hong Kong has one of the strongest links to Britain of any city in Asia, with Cathay Pacific, British Airways and Virgin Atlantic all operating the London route and direct service to Manchester as well. Since airlines began avoiding Russian airspace the flight has lengthened, but frequency remains high.
Best time to go
Hong Kong visitors arrive from a subtropical climate into a temperate one, and the contrast is sharpest in summer. A British July is dramatically cooler and less humid than a Hong Kong July, which is much of the appeal, and the long northern evening — daylight past ten at night in Scotland — is a genuine novelty.
May, June and September are the strongest months for weather and value together. All three sit below the July and August peak in British prices, and September benefits from the end of the British school holidays while the weather in the south often holds into October.
The Hong Kong calendar creates useful windows. Chinese New Year in January or February is a peak outbound period with high fares, but it lands in Britain's cheapest and quietest season — the two partly cancel out, and a February trip to London can still be very good value. Easter and the summer holiday overlap with the British peak in both price and crowds.
One practical note. Hong Kong is eight hours ahead of Britain in winter and seven during British Summer Time, since Hong Kong does not change its clocks. The difference therefore shifts twice a year, which catches out travellers with tight connections. Long-haul departures from Hong Kong leave in the small hours or late evening, when nothing can be resolved with the UK — another reason to have the ETA settled days rather than hours ahead.
Avoid these
Refusals are rare, and almost always technical rather than substantive. These are the problems that come up most often on applications from Hong Kong — we check for every one of them before submitting.
This is the defining issue for Hong Kong travellers. British National (Overseas) passport holders do not need an ETA — the BNO passport is a British travel document. Hong Kong SAR passport holders do. Applying for an ETA on a BNO passport wastes money; failing to apply on an SAR passport means being refused boarding. Confirm which document you will present before doing anything.
Mixed families are common in Hong Kong — some members on BNO passports, some on SAR passports, some already holding leave to remain under the BNO visa route. Each person's requirement follows the document they will actually travel on, so a family may need three different answers to the same question.
Hong Kong SAR passport holders are not currently in the ePassport gate cohort and will be seen at a staffed Border Force desk. BNO passport holders use the British and Irish lane. Families travelling on a mix of documents should expect to be separated at the border and agree a meeting point beyond it.
Hong Kong does not change its clocks, so the difference with the UK is eight hours in winter and seven during British Summer Time. Travellers who assume a constant offset misread connection times, particularly on itineraries continuing beyond London.
With so many Hong Kong families now split between the two countries, long visits are common. Six months is a per-visit maximum, not an annual budget, and Border Force considers entries cumulatively. A pattern of repeated long stays reads as residence and needs an appropriate visa route rather than successive ETAs.
The ETA must match the Roman-letter name in the machine-readable zone of the passport exactly, including the order and spacing of a romanised given name. Entering the Chinese characters, or a different romanisation you use professionally, creates a mismatch that can be flagged at check-in.
Passport number mistyped
By far the most common problem. The authorisation attaches to the number you enter, so a single wrong character produces an ETA that does not exist as far as the airline's check is concerned.
An undeclared conviction or refusal
The Home Office asks about criminal convictions and previous immigration refusals or removals. History found later is treated far more seriously than the original matter would have been if declared.
A photograph that fails the check
Shadows across the face, glasses, a patterned background or a cropped chin all cause the automated check to reject an image, which turns a routine approval into a manual review.
Conditions
These conditions are set by the UK Home Office and do not vary by nationality. The passport-linking rule in particular catches out a great many otherwise well-planned trips.
Your authorisation is held digitally against the passport number you enter. There is nothing placed in your passport and nothing to print for the border. If you renew or replace that passport, the ETA does not transfer — you must apply for a new one on the new document.
Every person travelling needs their own ETA, including babies and children. A child cannot be added to a parent's application, and each traveller needs their own valid passport to apply against.
An approved ETA lasts two years from the date it is granted, or until the expiry date of the passport it is linked to, whichever comes first. This is the single most misunderstood rule in the scheme — a passport with eight months left produces an ETA with eight months left.
Within its validity you can travel to the UK as many times as you like. Each individual visit can be up to six months. There is no formal annual cap, but repeated long stays that add up to the majority of the year will attract questions at the border.
One ETA covers England, Scotland, Wales and Northern Ireland, and it is also accepted for travel to Jersey, Guernsey and the Isle of Man. You do not need a separate authorisation for the Crown Dependencies.
An ETA lets you board your flight, train or ship. The decision to admit you is made by Border Force on arrival, who can ask about your funds, your accommodation, your onward plans and the purpose of your visit.
Consular services
The United Kingdom maintains a large consulate-general in Hong Kong, one of its biggest anywhere. It plays no part in issuing an ETA — the application is completed online and decided digitally, with no interview, no appointment and no passport submission. The consulate-general handles consular assistance, BNO and other visa services, and support for applicants whose circumstances require a human decision.
FAQs
The questions Hong Kong SAR passport holders ask most often about travelling to the United Kingdom.
No. Hong Kong SAR passport holders do not need a visa for tourism, business visits, short study or transit in the United Kingdom. Since January 2025 they do need an Electronic Travel Authorisation (ETA), a digital permission linked to the passport rather than a visa, applied for entirely online.
No. The British National (Overseas) passport is a British travel document and its holders are British nationals, so the ETA scheme does not apply to them. If you have moved to the UK under the BNO visa route you hold leave to remain, which carries its own permission to travel. Applying for an ETA on a BNO passport would be money spent unnecessarily.
Each person's requirement follows the document they will actually travel on. SAR passport holders need an ETA; BNO passport holders do not. A single family may therefore need different answers for different members. Confirm which passport each traveller will present at check-in, and apply only for those who need it.
No. Hong Kong SAR passport holders are not currently in the ePassport gate cohort and will be seen by a Border Force officer at a staffed desk. BNO passport holders use the British and Irish lane. Families travelling on a mix of documents should expect to be separated at the border.
Up to six months per visit. The ETA is valid for two years, or until your SAR passport expires if that is sooner, and permits unlimited entries within that period. Six months is a per-visit maximum rather than an annual allowance — repeated long stays will lead Border Force to ask whether you are living in Britain.
Eight hours in winter and seven during British Summer Time, because Hong Kong does not change its clocks. The difference therefore shifts twice a year. Check the actual local times on your itinerary rather than assuming a fixed offset, particularly if you have a connection beyond London.
Use the Roman-letter spelling exactly as printed in the machine-readable zone at the bottom of your passport photo page, including the order and spacing of a romanised given name. Do not enter the Chinese characters and do not use an alternative romanisation you may use professionally.
Yes, if travelling on an SAR passport. Every traveller needs an ETA regardless of age, including babies, and each is linked to that person's own passport. Hong Kong SAR passports for under-sixteens run for five years rather than ten, so check each expiry date — the ETA ends when the passport does.
Only for courses lasting up to six months, such as a summer school or a short language programme. An academic year, a full degree or a foundation programme requires a Student visa applied for from Hong Kong before travel. You cannot switch from within the UK after arriving on an ETA.
Yes. A single ETA covers the entire United Kingdom and is also accepted for Jersey, Guernsey and the Isle of Man. There are no internal immigration checks between the four nations, so a trip combining London, Manchester and Edinburgh needs only one authorisation.
