UK ETA for Mauritian Citizens

Do Mauritian Citizens Need a UK ETA?

The test attaches to the traveller and the passport. Where you buy your ticket, which airline carries you and which airport you depart from do not change the answer. The questions to settle are the passport you hold, the purpose of your visit and whether an exemption covers you.

The Start Date and Application Window

The ETA National List is arranged by travel date. Mauritius is in the group whose travel starts on 8 January 2025. The application process for that group opened on 27 November 2024, which means an application could be lodged well before the requirement applied to a particular trip.

Anyone flying to the UK on or after 8 January 2025 needs an approval in place before boarding. Waiting until the trip is close is risky, because the decision usually arrives within a day but can take up to three working days, and a problem with the details can add time.

Who Has to Apply

The requirement applies to a Mauritian national who intends to enter the UK as a Visitor for up to six months, and to a Mauritian national who must pass through UK border control to reach an onward destination. Tourism, family visits, short business meetings, brief courses and border-crossing connections all sit within that scope.

Exemptions are personal. If you are exempt, your companion may not be. Each traveller on a shared trip checks their own position, and each approval is issued separately.

Mauritian Citizenship and the Passport

The Passport and Immigration Office is the official authority for Mauritian passports. Its published eligibility rule covers citizens by birth, descent, adoption, registration or naturalisation, provided each legal condition is met. The office issues passports on that basis.

For the UK ETA, the central point is that an application must be made on a national passport that proves identity and nationality, and the resulting approval is linked to that passport. ETA 4.3 limits the approval to travel on the passport specified in the application. Keep the passport you will carry aligned with the approval from the start.

Expiry checks

Two dates matter. The approval ends two years after it is granted, or when the linked passport expires, whichever is earlier. Read the expiry printed on the data page, then compare it with the expiry on your approval. A passport near the end of its life produces a short approval.

This guide does not state how long a Mauritian passport is valid or how long children’s passports last. The office’s public pages describe the documents required, not the validity period, so the question has been left out rather than guessed.

A Lost, Stolen or Damaged Passport

The Passport and Immigration Office instructs that a lost or stolen passport must be reported at once to a police station in the area where it went missing. The police issue a declaration that you then present when applying for a replacement. A reported passport should not be used for travel unless the office has authorised that use.

For the ETA, the replacement is a different document. The approval linked to the lost passport does not move to the new one. Apply for a fresh approval with the replacement passport before you travel, and keep the police declaration with you until the trip is complete.

Renewing a Mauritian Passport

Renewal under the office’s published procedure asks for the previous passport, with a photocopy of its biodata page, a renewal form, two recent photographs taken against a light background, and a national identity card for adults. The renewed booklet is a new document with its own number.

For the ETA, a renewal has the same effect as a replacement. An approval tied to the previous booklet is not transferred. If the requirement still applies after the renewal, apply again using the new passport. Carry the old passport only where it remains useful as evidence, and do not rely on it for entry.

Gathering the Details for the ETA

The UK application asks for personal information that must line up with the passport. Assemble it before you begin, so that you are not guessing details from memory:

• The passport you will travel on, with the biodata page clear for the photograph.
• Your name exactly as printed, including every given name.
• Passport number, date of issue, expiry date, date of birth and place of birth.
• An email address you check often, because the outcome is sent to you there.
• A payment card or a supported digital wallet.
• A recent facial image that meets the UK photograph standard.
• Your travel dates and a clear statement of your purpose, so the activities can be checked against the Visitor rules.

The Mauritian national identity card matters at home, and the Passport and Immigration Office asks for it in several applications, but it is not part of the UK ETA application. The application is completed on the passport, and the passport is what you present at the border.

Making the Application

The UK ETA mobile app or the online form can be used. The app takes a scan of the passport and a face image from your phone. The online route needs a photograph of the passport page and a face image, both meeting the rules.

The application includes a fee, which is paid within the process; this guide does not quote an amount. Use only the official route. Some third-party sites copy the look of government services or promise faster decisions, and neither helps your application.

After you apply

Decisions are normally emailed within a day, and can take up to three working days. The email contains a 16-digit reference. Hold off on booking non-refundable travel until the email arrives. If it does not come after three working days, check your junk folder before contacting UK Visas and Immigration.

The application fee is not refunded once you have applied. A rejection, or a change to the details, means submitting again.

How Long the Approval Lasts

The approval runs for two years from the grant date or until the linked passport expires, whichever is earlier. It is not extended when you replace or renew the passport. A new approval is the only way to cover travel on the new document.

Note the reference number, the grant date and the passport expiry. A simple written record makes it easy to see when the next application is due.

Repeat Trips and the Length of Each Visit

While the approval is in force, you can travel to the UK on more than one occasion. Each arrival is assessed by the border officer again, and each stay may run for up to six months as a Visitor.

The six-month maximum is per visit. It does not roll over into the next visit. If your trips become frequent and long, expect closer questions at the border, and be ready to explain why each trip is a visit rather than a settled pattern of living in the UK.

Children and Minors

The UK rule is simple: a child needing an ETA must have one linked to the child’s own passport. That includes an infant. A parent’s approval cannot be used by a child, and a child’s approval cannot be used by a parent.

If the child is travelling with the applicant, the app can be used. If the child is elsewhere, the application must be made online with a photograph of the child’s passport and a face image of the child. Each person’s approval is decided separately, and the outcomes may arrive on different days.

For a child’s passport in Mauritius, the office requires that parents or guardians sign the application form, and where a parent is abroad, that consent is certified by an approved official. If you are preparing a child’s passport, that paperwork is the Mauritian side of the job; the UK approval is a separate step taken with the finished passport.

Check the child’s passport expiry before booking. The approval ends with the passport, and a child’s passport that is about to expire will limit the approval.

Dual Nationality and British or Irish Citizenship

The UK rules deal with dual nationals in one clear way: anyone with British or Irish citizenship cannot obtain an ETA. Such a traveller uses the British or Irish passport and proves that citizenship at the border, which may include another valid passport carrying a certificate of entitlement for British nationals.

If your other nationality is one that needs an ETA or a visa, the rules attach to the passport you intend to show. An approval applied for on a Mauritian passport covers only that passport. This guide does not describe whether Mauritius recognises particular dual arrangements; that is a question for the Mauritian authorities.

Irish Residence Under ETA 1.3 and 1.4

ETA 1.3 provides that an applicant who is lawfully resident in the Republic of Ireland, and who travels to the UK from elsewhere in the Common Travel Area, does not need to obtain an ETA. ETA 1.4 sets the test for lawful residence: resident in Ireland, entitled to reside there under the relevant rules at the time of the application, and not subject to a bar on leaving Ireland without an Irish minister’s consent.

The rule contains no nationality limit. The Home Office caseworker guidance is a separate document. It describes the exemption as covering non-visa nationals who are lawfully resident in Ireland, and it states that the exemption does not reach travel from outside the Common Travel Area.

Evidence and age

The guidance lists documents that can show lawful residence, among them the Irish Residence Permit. It describes that permit as available to third-country nationals resident in Ireland aged 16 and over. That is a description of the document, and it does not narrow ETA 1.3.

Anyone aged 16 or over who relies on the exemption may be asked for that evidence. Sixteen and seventeen year olds can be asked for it too. Children under 16 are not normally asked, though they or an adult travelling with them may be questioned.

Leaving Mauritius for the UK

Your departure point does not change the ETA test. A journey that starts in Mauritius needs the same approval as any other journey on the same passport, and the question of an exemption is still answered by your personal circumstances.

Whether a journey includes a connection depends on the itinerary issued to you. Once you know the connecting airports, each change of aircraft must be checked against the transit rules below. This guide does not describe specific airlines, routes or airport procedures, because those are not part of the ETA rules and would need verifying separately.

Obtain the approval before you set off. Fixing a passport or contact detail while you are abroad is far harder than correcting it at home.

Connections, Border Control and Transit

Two kinds of connection need separating. In an airside connection you remain in the secure zone between flights and never reach UK border control. In a landside connection you pass through UK border control, even if you leave the terminal briefly and come back.

Under the present guidance, an ETA-eligible traveller in airside transit, without passing through border control, does not need an ETA. An ETA-eligible traveller passing through border control, landside, generally needs an ETA before departure, unless another exemption applies. Confirm the current guidance before booking, because the airside rule is not described as permanent.

When in doubt, assume that a connection is landside, and secure the approval first. Your airline can confirm whether your itinerary passes through UK border control. For a fuller explanation, see our transit and layovers article.

Jersey, Guernsey and the Isle of Man

Jersey, Guernsey and the Isle of Man are Crown Dependencies. They are self-governing and outside the UK, while belonging to the Common Travel Area. An ETA can cover travel to all three for up to six months, which can make a combined trip simpler to arrange.

That coverage is not the same as local arrival practice. Each island sets its own arrival arrangements. Look up the rules for the specific island before you travel, rather than relying on the UK position.

Tourism and Family Stays

Holidays, sightseeing, a trip to see relatives or friends and a short recreational course are all covered by the Visitor rules. An approval supports up to six months per visit, provided the stay remains a visit.

Recreational courses are capped at 30 days, and English-language training is excluded from that allowance. Visits connected with a state-funded or independent school, such as a school exchange, are also permitted within the Visitor rules.

A family stay that drifts toward living in the UK falls outside the Visitor rules. For a longer family arrangement, consider the correct route before booking. Our visiting family and friends guide covers where that line sits.

Business Trips and Meetings

Business travel under the Visitor rules includes meetings, conferences, seminars, interviews, workshops and debates. It also covers short talks that are not run for profit, signing contracts, promotional attendance at trade fairs, site inspections and briefings for a UK customer.

The conditions are equally specific. Trade-fair work must be promotional, with no direct sales. Work for a UK customer must be carried out overseas, not in the UK. Overseas employment tasks can be done remotely from the UK, but only if they are not the main reason for the trip.

Unpaid volunteering for a registered charity is allowed for up to 30 days in total. Paid work for a UK employer, or any role that fills a post in the UK, needs another route. Our business visits guide provides examples.

Short-Term Study

A Visitor may study in the UK for up to six months, if the study conditions in the Visitor rules are met. Study is not a route to work, and the study period must close within the six-month limit.

Anything longer, or leading to extended stay, belongs to a different category. A student planning more than six months, or planning paid part-time work, should review the alternatives before applying. An ETA is not a student visa. Details are in our short-term study guide.

Permitted Paid Engagements

Visitors may take on certain paid engagements, provided the engagement is completed within 30 days of entering the UK and meets the conditions of the permitted paid engagement rules. Engagements that run beyond that window, or that fall outside those conditions, are outside the Visitor route.

Treat each paid booking as a question to check, not an assumption. Record what you are paid for, the dates and the paying organisation. Our permitted paid engagements guide sets out the conditions.

The Creative Worker Concession

The Immigration Rules provide a Creative Worker route. ETA 1.1(f)(ii) refers to an applicant seeking entry as a Creative Worker under the Temporary Work rules, and ETA 4.2(b) permits multiple journeys for that purpose.

The Visitor rules separately allow artists, entertainers and musicians to give performances, attend rehearsals and auditions, and take part in promotional appearances. That permission is narrower than the Creative Worker concession. For paid creative work, read our creative worker concession guide before applying.

Comparing an ETA with a Standard Visitor Visa

The choice between an ETA and a visa depends on nationality and purpose. Mauritius is on the ETA National List, which applies to non-visa nationals. A Mauritian passport holder visiting for a Visitor purpose therefore usually needs an ETA rather than a visa.

A visa becomes necessary when the purpose, the length or the circumstances fall outside the ETA. Examples include long study, employment and residence. Our UK visa guide lists the situations that call for one.

UK Rules Compared with Schengen

The UK sits outside the Schengen Area and runs its own entry rules. A stay in a Schengen state gives no permission to enter the UK, and a UK approval gives no permission to move around the Schengen Area.

On a multi-country itinerary, the UK leg needs its own approval, its own paperwork and its own six-month cap. Do not assume that a permission issued for another country covers the UK segment.

Criminality and Refusal Grounds

ETA 2.2 sets out the criminality grounds on which an application must be refused, and they operate as two separate tests. ETA 2.2(a) covers a conviction in the UK or overseas for which a custodial or suspended sentence of 12 months or more was received. ETA 2.2(b) covers any criminal conviction in the UK or overseas, whatever the sentence, unless more than 12 months have passed since the date of conviction.

The first test looks at the length of the sentence. The second looks at the date of the conviction and applies even where the penalty was small or a fine. Read both before applying. Our refused and rejected applications article explains what to do after a refusal.

Further refusal grounds are set out in ETA 2.3 to 2.9. These cover conduct that makes presence in the UK undesirable, certain earlier immigration breaches including overstays after age 18, false or incomplete information, earlier cancellations, and previous Visitor refusals. The rules contain exceptions to several grounds, so consult the full text when a point is unclear.

This guide offers no prediction of how any application will turn out. If a ground might apply to you, look at the rule and take advice first.

Mistakes That Cause Trouble

• Completing the application with the national identity card rather than the passport.
• Typing the number of a passport that has been replaced or reported lost.
• Attributing a child’s details to a parent’s passport, or the reverse.
• Relying on a Schengen permission or an approval for another country to cover the UK.
• Booking non-refundable travel before the decision email arrives.
• Confusing a landside connection with an airside one.
• Using a site that resembles a government service or promises quicker results.
• Forgetting that the approval ends when the passport does, however long the approval runs.

Pre-Departure Checklist

Work through these items before you travel:

• Confirm the passport you carry matches the approval, including its expiry date.
• Keep the reference number and the decision email with your travel papers.
• Map each connection and mark it airside or landside.
• Look up entry arrangements for any island on the itinerary.
• If you rely on the Irish exemption, carry the original residence document.
• For a child, carry the passport and check its expiry against the approval.
• Write down the purpose of the visit and the activities you plan.

An approval does not guarantee entry to the UK. The border officer decides on admission and may ask about the reason for the visit and its duration.
