UK ETA for Hong Kong BN(O) Passport Holders: What the Rules Say

If you hold a British National (Overseas) passport from Hong Kong, you might be wondering whether you can use the new UK Electronic Travel Authorisation (ETA) scheme. The short answer is yes — but there are important details to get right. This guide explains everything you need to know about the UK ETA for BN(O) passport holders, including who qualifies, how to apply, and how it differs from the BN(O) visa route.

The UK ETA is a digital permission to travel to the UK for short stays. It's not a visa — it's an electronic authorisation linked to your passport. For BN(O) passport holders, the ETA offers a straightforward way to visit the UK for tourism, business, or transit without needing a full visa.

But you must use your BN(O) passport when applying, and you must meet the standard eligibility criteria.

This article covers the rules, fees, and application steps, plus common questions BN(O) holders have about the ETA. Remember, this is general guidance — always check official sources before you travel.

Can BN(O) Passport Holders Apply for a UK ETA?

Yes. The UK government allows BN(O) passport holders to apply for an ETA, just like any other non-visa national. The ETA is designed for nationals of countries that do not normally need a visa for short visits to the UK.

Hong Kong BN(O) passport holders fall into this category.

However, there's a catch: you must apply using your BN(O) passport. If you also hold a Hong Kong Special Administrative Region (HKSAR) passport or another nationality, you cannot use that passport for the ETA application. The ETA is linked to the passport you use to apply, and you must travel with that same passport.

If you have multiple passports, always use your BN(O) passport when applying for the ETA and when entering the UK. Using a different passport could cause delays or refusal at the border.

UK ETA vs BN(O) Visa: What's the Difference?

This is the most common source of confusion. The UK ETA and the BN(O) visa are two completely different things. Here's a quick breakdown:

If you're planning a holiday, a business meeting, or a stopover, the ETA is all you need. If you want to move to the UK, work, or study long-term, you need the BN(O) visa. You cannot use an ETA to enter the UK and then switch to a BN(O) visa — you must apply for the visa from outside the UK.

Who Needs a UK ETA? (And Who Doesn't)

Before you apply, check if you actually need an ETA. The UK government has a list of nationalities that require an ETA for short visits. BN(O) passport holders are on that list.

But there are exceptions:

• If you have a valid UK visa (including a BN(O) visa), you do not need an ETA — your visa covers your entry.
• If you have settled status (Indefinite Leave to Remain) or British citizenship, you do not need an ETA.
• If you are a British Overseas Territories citizen, you may have different rules.

For most BN(O) passport holders visiting for a short trip, the ETA is the correct route. For a full breakdown of who needs an ETA, see our guide on who needs a UK ETA.

UK ETA Application Requirements for BN(O) Passport Holders

The application process is the same for BN(O) holders as for any other eligible nationality. You'll need:

• A valid BN(O) passport with at least 6 months validity from your date of travel.
• A digital passport photo (or you can take one with your phone).
• An email address to receive the ETA confirmation.
• A debit or credit card to pay the £20 fee.
• To answer a few questions about your travel plans and background.

You do not need to submit any supporting documents like flight bookings or hotel reservations. The application is straightforward and takes about 10 minutes. For detailed step-by-step instructions, see our complete UK ETA application requirements guide.

Using Your BN(O) Passport: Important Notes

When you apply, enter your BN(O) passport details exactly as they appear. The system will ask for your passport number, expiry date, and nationality. Select "British National (Overseas)" as your nationality — do not select "British" or "Hong Kong."

If you have a Hong Kong Special Administrative Region (HKSAR) passport as well, do not use it for the ETA. The ETA is only available for BN(O) passport holders from Hong Kong. HKSAR passport holders need a visa to visit the UK (unless they also have another eligible nationality).

How Much Does a UK ETA Cost?

The UK ETA fee is £20 per person. This is the same for all applicants, including BN(O) passport holders. The fee is non-refundable, even if your application is refused.

For more details on fees and payment methods, check our article on how much does a UK ETA cost.

Compare this to the BN(O) visa fee of £180 (plus the Immigration Health Surcharge of around £624 per year). The ETA is far cheaper, but it only covers short visits.

How to Apply for a UK ETA as a BN(O) Passport Holder

Applying is simple. Follow these steps:

1. Go to the official UK ETA application website or use the UK ETA app (available for iOS and Android).
2. Create an account with your email address.
3. Enter your BN(O) passport details.
4. Upload or take a passport-style photo.
5. Answer the eligibility questions (criminal record, immigration history, etc.).
6. Pay the £20 fee using a debit or credit card.
7. Submit your application. You'll usually get a decision within minutes, but it can take up to 72 hours.

Once approved, your ETA is electronically linked to your BN(O) passport. You don't need to print anything — but it's a good idea to save the confirmation email. The ETA is valid for 2 years (or until your passport expires, whichever comes first).

What Can You Do With a UK ETA?

With an approved ETA, you can:

• Visit the UK for tourism, holidays, or to see family.
• Attend business meetings, conferences, or events (but not work).
• Transit through a UK airport to another country.
• Study a short course (up to 6 months).
• Get married or register a civil partnership (but you must give notice first).

You cannot:

• Work in the UK (including paid or unpaid work).
• Live in the UK long-term.
• Access public funds (benefits).
• Study a full degree course (you need a Student visa for that).

If you're unsure whether your planned activity is allowed, check the UK government's visitor rules.

Can You Switch From an ETA to a BN(O) Visa?

No. You cannot enter the UK on an ETA and then apply to switch to a BN(O) visa from inside the UK. The BN(O) visa application must be made from outside the UK, typically from Hong Kong or another country where you are resident.

If you want to move to the UK permanently, you must apply for the BN(O) visa before you travel. Once you have the visa, you can enter the UK and start living, working, or studying. The ETA is only for short visits.

What Happens at the UK Border?

When you arrive in the UK, present your BN(O) passport to the Border Force officer. They will scan your passport and check that you have a valid ETA. You may be asked questions about your travel plans, accommodation, and intended stay.

Be prepared to show:

• Your return or onward ticket.
• Proof of accommodation (hotel booking, invitation from family).
• Evidence of sufficient funds for your stay.

If you have a valid ETA but the officer suspects you plan to work or stay longer than allowed, you could be refused entry. Always be honest about your intentions.

Common Mistakes BN(O) Holders Make With the ETA

Here are pitfalls to avoid:

• Using the wrong passport: Always use your BN(O) passport. Using an HKSAR passport will result in refusal.
• Applying too late: Apply at least 72 hours before travel. Most approvals are instant, but delays happen.
• Overstaying: The ETA allows visits up to 6 months. Overstaying can affect future applications.
• Confusing ETA with BN(O) visa: They are not interchangeable. Choose the right one for your purpose.

Understanding the UK ETA Validity Period for BN(O) Holders

The UK ETA is valid for 2 years from the date of approval. However, if your BN(O) passport expires before that 2-year period ends, the ETA expires with it. For example, if your passport has only 1 year of validity left, your ETA will be valid for just that 1 year.

You can make multiple trips to the UK during the ETA's validity. Each visit can last up to 6 months. If you get a new BN(O) passport, you must apply for a new ETA, even if the old one still has time remaining.

How the UK ETA Affects BN(O) Visa Applications

Some BN(O) passport holders consider using an ETA for a short visit before applying for the BN(O) visa. This is allowed, but you must leave the UK before applying for the visa. The BN(O) visa application requires you to be outside the UK at the time of submission.

Using an ETA for a short trip does not affect your BN(O) visa application. However, if you overstay on an ETA or violate its conditions, that could harm your future visa chances. Always comply with the rules of your ETA.

Traveling With Family Members as a BN(O) Holder

If you are a BN(O) passport holder traveling with family, each person needs their own ETA or visa. Children, including infants, must have their own ETA linked to their own BN(O) passport. You cannot include dependents on your ETA.

For family members who are not BN(O) holders, check their eligibility separately. For example, a spouse with an HKSAR passport may need a Standard Visitor visa instead of an ETA. Plan ahead and verify each person's requirements.

What to Do If Your BN(O) Passport Is Lost or Stolen

If your BN(O) passport is lost or stolen after you receive an ETA, the ETA becomes invalid. You must report the loss to the authorities and apply for a replacement passport. Once you get a new BN(O) passport, you need to apply for a new ETA.

Do not travel with a lost or stolen passport, even if you have the ETA confirmation email. The ETA is electronically linked to the specific passport number you used during application. A new passport number means a new ETA application is necessary.

Understanding the Application Process in More Detail

The UK ETA application system is designed to be user-friendly. You can complete it entirely on your smartphone or computer. The app guides you through each step with clear instructions.

During the application, you will be asked about your travel history and any previous UK immigration violations. Be honest in your answers, as false information can lead to refusal. The system cross-checks your details with UK databases.

If you make a minor error, like a typo in your passport number, your application may be delayed or refused. Double-check all entries before submitting. You can save your progress and return later if needed.

What to Expect After You Apply

Most BN(O) applicants receive a decision within minutes. The system sends an email confirming approval or refusal. If approved, the ETA is automatically linked to your BN(O) passport number.

In some cases, the application may require manual review, which can take up to 72 hours. If you haven't heard back after 3 days, check your spam folder or contact UKVI. Plan your travel accordingly to avoid last-minute stress.

Once approved, you do not need to carry any printed document. However, saving the confirmation email can be helpful if you need to prove your ETA status. The border officer will see the ETA when they scan your passport.

How the UK ETA Differs From a Standard Visitor Visa

Some BN(O) holders may wonder whether to apply for an ETA or a Standard Visitor visa. The ETA is simpler, cheaper, and faster. It requires no supporting documents and is valid for multiple entries over 2 years.

A Standard Visitor visa costs more (around £115) and requires a longer application process. It may be necessary if you have a criminal record or previous immigration issues. The ETA is the preferred option for most short visits.

If your ETA application is refused, you can still apply for a Standard Visitor visa. The visa process allows for more detailed consideration of your circumstances. Always check which route suits your situation best.

Understanding the Eligibility Criteria for BN(O) Holders

To qualify for a UK ETA as a BN(O) holder, you must meet specific criteria beyond just holding the passport. You must not have a serious criminal record that would make you a threat to the UK. You must also not have previously breached UK immigration laws, such as overstaying a visa.

The system checks your details against UK security databases. If you have a history of immigration violations, your application may be refused. For example, if you were previously deported from the UK, you cannot get an ETA.

If you are unsure about your eligibility, consult the official UK government guidance. You can also consider applying for a Standard Visitor visa, which allows for a more detailed review of your case.

How to Prepare for Your UK ETA Application

Before you start the application, gather all necessary information. Have your BN(O) passport ready and check that it has at least 6 months of validity. Ensure your digital photo meets the requirements, such as a plain background and no glasses.

Make sure you have a stable internet connection and a device with a camera. The app may require you to take a live photo during the process. Prepare your payment card, as the £20 fee is charged immediately.

Set aside about 10-15 minutes to complete the application without interruptions. Rushing can lead to errors, so take your time. If you need help, the app provides on-screen guidance.

What to Do If You Make a Mistake on Your Application

If you realize you made a mistake after submitting, you cannot edit the application. You must submit a new application with the correct information. The £20 fee for the first application is non-refundable.

Common mistakes include entering the wrong passport number or selecting the wrong nationality. Double-check all entries before clicking submit. If you are unsure about any field, refer to the official guidance.

If your application is refused due to an error, you can reapply with corrected details. However, repeated refusals may raise flags, so be careful. Contact UKVI if you need assistance.

Traveling to the UK for Business Purposes

With a UK ETA, you can attend business meetings, conferences, and events. You can also negotiate contracts or conduct site visits. However, you cannot work for a UK employer or receive payment from a UK source.

For example, you can travel to London for a two-day conference on finance. You can meet with clients and discuss potential deals. But you cannot take on a temporary job or provide services directly.

If your business activities are more extensive, you may need a Business Visitor visa. The ETA is limited to short-term business interactions. Always check the rules before planning your trip.

Frequently Asked Questions

Can I use my HKSAR passport for the UK ETA?

No. The UK ETA is only available for nationals of eligible countries and territories. Hong Kong Special Administrative Region (HKSAR) passport holders are not eligible for an ETA and must apply for a Standard Visitor visa instead. If you hold a BN(O) passport, you must use that one.

Do I need a UK ETA if I have a BN(O) visa?

No. If you hold a valid BN(O) visa (endorsed in your passport or as a biometric residence permit), you do not need an ETA. Your visa allows you to enter the UK for the purpose it was granted (living, working, or studying). The ETA is only for short visits without a visa.

How long does the UK ETA last for BN(O) passport holders?

The UK ETA is valid for 2 years from the date of approval, or until your BN(O) passport expires — whichever comes first. During that period, you can make multiple visits to the UK, each staying up to 6 months. If you renew your passport, you must apply for a new ETA.

Can I study in the UK with a UK ETA as a BN(O) holder?

You can take a short course of study (up to 6 months) with an ETA. For example, a language course or a short academic programme. However, if you plan to study a full degree or a course longer than 6 months, you need a Student visa or a BN(O) visa (which allows study).

The ETA does not permit long-term study.

What if my UK ETA application is refused?

If your ETA application is refused, you will receive a reason. Common reasons include incorrect passport details, criminal record issues, or previous immigration violations. You can reapply with corrected information, but the £20 fee is non-refundable.

If you believe the refusal was an error, you can contact UKVI. Alternatively, you can apply for a Standard Visitor visa instead, which has a more detailed assessment process.
