Irish citizenship by birth and through a grandparent

Does Ireland give citizenship by birth?

Until 2005, anyone born on the island was Irish. On 11 June 2004, 79% of those who voted backed the 27th Amendment to the Constitution, and since 1 January 2005 birthplace alone no longer gives a passport. Michael McDowell, then Minister for Justice, said that 40% to 50% of nationals from outside the European Union giving birth in Ireland were doing so to get citizenship for their child.

Today it all turns on the parents' status on the day of the birth. Section 6A of the Irish Nationality and Citizenship Act 1956 makes a child born on the island of Ireland a citizen from birth if at least one parent:

• is an Irish citizen or entitled to be one;
• is a British citizen;
• is entitled to live in Ireland or Northern Ireland without any time limit, for example on Stamp 5 - permission to remain without condition as to time;
• has lived on the island for at least 3 of the 4 years before the birth, on a status the law counts.

The island is the key word: Irish law treats birth and lawful residence in Northern Ireland, which is part of the United Kingdom, almost the same as in Dublin.

A safety net exists: a child born in Ireland with no right to any other citizenship is Irish automatically. It rarely helps families from Russia or Ukraine, whose children are entitled to their parents' citizenship.

Which years count towards the 3 out of 4?

Three years out of four means reckonable residence, not just any time in the country. Section 6B of the Act strikes out several kinds of time: living without lawful status, a permission to study, time waiting for a decision on an international protection (asylum) application, and periods after a return decision. The Passport Service adds a parent's diplomatic immunity to the list.

Worked example. A couple moved to Dublin on 1 March 2023 on a Critical Skills Employment Permit and renewed without any gaps. By 1 March 2026 they had 3 years of reckonable residence, so a child born after that date is Irish from birth. Had they spent the first two years studying on Stamp 2, the clock would only have started when they switched to a work permit.

European Union, EEA (the European Union plus Norway, Iceland and Liechtenstein) and Swiss citizens hold no residence permissions, so they sign Declaration Form A, a witnessed statement of their residence, backed by P60 tax certificates (the employer's annual pay and tax statement) showing at least 35 insurable weeks a year, bank statements or a lease.

How do you get an Irish passport for a child born in Ireland?

Ireland does not issue a separate citizenship certificate to citizens by birth: their document is the passport. That is why the parents' three years are checked by the Passport Service of the Department of Foreign Affairs and Trade when it issues the child's first passport.

• Register the birth. Parents register the child with the civil registration service, and the record goes to the General Register Office (GRO). The child also needs a PPSN (Personal Public Service Number), the personal number used for tax and public services.
• Apply online. Passport Online is the fastest route. If the birth is registered with the GRO, you give the child's PPSN and guardianship is joint on the birth certificate, you do not need to send the original certificate: the service retrieves the record digitally.
• Documents from a parent from outside the European Union. The original national passport with permission stamps covering 3 of the 4 years before the birth (an expired one is fine), the Irish residence permit card (formerly the immigration registration card) and a summary of permission stamps signed by the parent on the Department of Foreign Affairs template: passport number, holder's name, description of the stamps and the dates of each permission.
• If a parent is a refugee. The original refugee or subsidiary protection declaration, the passport or travel document, and Irish residence permit cards covering the full period.
• Fee. A 5-year child passport through Passport Online costs $22 (20 euros), or $51 (45 euros) with a Passport Card, plus a $6 (5 euros) postal fee for each child application.

The parents' originals stay with the Passport Service during processing and come back within 20 working days of the passport being issued. The Irish Department of Foreign Affairs advises against booking travel until you have them.

If a parent holds any other form of protection, the Passport Service asks you to contact it first, as different requirements may apply. This mainly affects Ukrainians on temporary protection.

What if the child did not get citizenship at birth?

If the parents were short of three years at the birth, the child can still become Irish by naturalisation after just 3 years of living in the country, not the 5 years adults need. The rule came in with the Courts and Civil Law (Miscellaneous Provisions) Act 2023 and has applied since 31 July 2023.

The test for a child born in Ireland is 1 year of continuous residence immediately before the application plus 2 more years in total during the previous 8. Up to 70 days abroad are allowed in the continuous year. A parent, guardian or person acting in loco parentis applies through the portal of the Irish immigration service, the immigration arm of the Department of Justice, Home Affairs and Migration.

Two limits: the rule does not cover children born in Northern Ireland, whose residence there does not count, and years on student permissions do not count either.

State fees: $197 (175 euros) on application, not refunded if refused, and $225 (200 euros) for a minor's certificate of naturalisation after approval. $422 (375 euros) in total.

Worked example. A child is born in Cork when the mother has 2 years on a Critical Skills permit. No citizenship at birth. If the family stays on work and family permissions, the parents can apply to naturalise the child 3 years after the birth. By then the mother will have 5 years and can apply for herself too.

Do parents get Irish citizenship when their child is born in Ireland?

Not automatically. An Irish child gives a parent the right to live and work in the country, but the parent has to earn a passport the usual way: at least 5 years of reckonable residence.

The right to stay: Stamp 4 under Zambrano

In 2011 the Court of Justice of the European Union ruled in Ruiz Zambrano (C-34/09) that a European Union country cannot deny a parent from outside the European Union the right to live and work alongside a dependent child who is a European Union citizen. Ireland applies this through a dedicated immigration service procedure for parents of Irish citizen children.

The conditions: the child holds an Irish passport, is under 18 and lives in Ireland full time, and the parent is named on the birth certificate and involved in raising and supporting the child. The immigration service may ask for a DNA test at its approved laboratory, Ormond Quay Paternity Services, at your expense. The outcome is Stamp 4 for up to three years, though sometimes for only six months. Renewing this permission costs $337 (300 euros). There is no appeal against a refusal, but you can apply again.

In practice this route matters where the child became Irish through one parent, say an Irish or British citizen, and the other parent has no status of their own. If the child is Irish thanks to your own three years, you already have status.

A passport for the parents: 5 years or more

Adult naturalisation needs 5 years of reckonable residence: 1 continuous year before applying and 4 years in total during the previous 8. Up to 70 days abroad are allowed in the final year, and in exceptional circumstances the Minister can accept up to 100. Spouses of Irish citizens need 3 years of marriage and 3 years on the island. There is no language test today.

State fees: $197 (175 euros) to apply and $1,070 (950 euros) for an adult certificate. The immigration service says most, but not all, applications are processed within 12 months. There is no appeal against a refusal.

How do you get Irish citizenship through a grandparent?

This is the most underrated route to a European Union passport: if a grandparent was born on the island of Ireland, you do not need to live in the country or speak any language, and the decision rests on documents rather than on ministerial discretion as with naturalisation. For an adult it costs $313 (278 euros) in fees and about a year of waiting.

The mechanism is the Foreign Births Register, run by the Department of Foreign Affairs. The rules:

• A parent was born on the island of Ireland and was a citizen when you were born. You are Irish from birth, no registration needed, and you can apply for a passport straight away.
• A grandparent was born on the island, your parent abroad. You need a Foreign Births Register entry. Birth in Northern Ireland counts, and your parents do not need to have held Irish passports.
• Your parent became Irish by naturalisation or the Foreign Births Register before you were born. Also a Foreign Births Register entry.

Foreign Births Register citizenship starts on the date of registration, not the date of birth, and that shapes the rights of the next generation.

What documents does the register need?

The form is online only and the fee is paid there, while the originals go by post: the register has no public office. An adult applying through a grandparent needs:

• the form, signed and witnessed by someone from the list of professions on it;
• your original civil birth certificate showing your parents' names, plus a marriage or change of name document if your surname changed;
• certified photo ID, two original proofs of address and 4 colour photos, two of them witnessed;
• the same birth and marriage certificates for your parent and grandparent, with certified copies of their ID or their death certificates.

If the grandparent was born before 1864, when civil birth registration began in Ireland, a baptismal certificate is accepted. Irish certificates are ordered from the GRO, and for Northern Ireland from GRONI, its northern counterpart. All originals are returned by registered post at the end of the process.

How much does it cost and how long does it take?

The fee for adults is $313 (278 euros): registration and certificate plus $9 (8 euros) postage. For under-18s it is $172 (153 euros). The Department of Foreign Affairs gives a timeline of about 12 months for a complete application, processed in strict date order. You cannot apply for a passport in parallel: Foreign Births Register certificate first, passport second. Siblings living in the same country can send their applications in one envelope with a shared set of documents.

Can you get Irish citizenship through a great-grandparent?

Yes, but only if your parent was entered in the register before you were born. Missing that by a single day closes the route: the Department of Foreign Affairs states plainly that children born before a parent's registration are not eligible.

Hence a practical rule for anyone with an Irish grandparent planning children: apply to the register before a pregnancy, not after. If a baby may arrive before the roughly one-year queue clears, the Department of Foreign Affairs asks you to flag it on the application and contact the Foreign Births Register service hub.

Great-great-grandparents, uncles, aunts and cousins give no right to citizenship. What remains is Irish associations, naturalisation based on Irish ties: the Minister may grant citizenship to someone related to an Irish citizen by blood, affinity or adoption, but it is entirely discretionary.

Against that backdrop, Ireland's two-generation rule looks generous, especially after Italy's 2025 reform shut the door on most distant descendants of emigrants.

How much do Irish citizenship and a passport cost?

The cheapest way into the European Union on this page costs from $397 (353 euros): $313 (278 euros) for an adult Foreign Births Register entry and $84 (75 euros) for the passport. Naturalising a family of four costs $3,370 (3,000 euros) in state fees alone.

Worked example 1. A brother and sister live outside Ireland and their grandmother was born in Galway. They apply to the register in one envelope: $625 (2 × 278 = 556 euros). After registration, two passports online with postage: $203 (2 × 90 = 180 euros). That is $827 (736 euros) in state fees, before ordering certificates and translations.

Worked example 2. A family of two adults and two children naturalises after 5 years in the country: $787 (4 × 175 = 700 euros) on application and $2,590 (2 × 950 + 2 × 200 = 2,300 euros) after approval. $3,370 (3,000 euros) in total, plus every permission renewal along the way.

Residents get pregnancy care and birth in the public system free: the Maternity and Infant Care Scheme covers anyone who lives in Ireland or intends to stay at least a year.

Ireland, the United Kingdom, Germany, Portugal or Spain: where is it easier for a child to get a passport?

By European standards, Ireland's 3 of 4 years is one of the mildest tests. Germany and Portugal ask for 5 years, the United Kingdom for a parent who is a citizen or permanently settled, and Spain almost never grants citizenship by birth to children of foreigners.

Ireland's drawbacks lie elsewhere: Russians need a visa, and parents must still live there for at least 5 years. For countries that grant citizenship for the bare fact of birth, see our review of giving birth abroad for citizenship.

What changes in 2026: the citizenship bill

On 9 September 2026 the Irish government approved priority drafting of the Irish Nationality and Citizenship (Amendment) Bill 2026. Justice Minister Jim O'Callaghan called the proposals "balanced, proportionate and necessary", while Minister of State for Migration Colm Brophy put the government's view more bluntly: citizenship is "a privilege, not a right". On 21 September the department published the General Scheme, in effect a first draft, for pre-legislative scrutiny by the Oireachtas Justice Committee.

What the draft proposes:

• 8 years instead of 5. For most adults: 2 continuous years before applying and 6 years in total during the previous 10.
• Spouses of citizens. At least 5 years of marriage instead of 3, and longer residence.
• Tests. A language test in English, Irish or Irish Sign Language, and a civics test on how Irish society, government and the Constitution work.
• Self-sufficiency. A minimum income to be set by the Minister, and no prescribed social welfare or housing payments in the 2 years before applying, with up to 6 months tolerated.
• Temporary protection won't count. Years Ukrainians spend on temporary protection would not count towards naturalisation.
• Citizenship by birth. For children born after the law takes effect, periods that do not count for naturalisation would also stop counting towards the 3 of 4 years. In practice that mainly means temporary protection.

The draft does not touch the grandparent route or the register. For naturalisation it spells out a transitional rule: the new limits on reckonable residence will not apply to applications made before the law takes effect. On 24 September Taoiseach (prime minister) Micheál Martin signalled that workers already living in Ireland may keep the 5-year rule, with the Justice Minister working on the details.

Be clear about its status: this is a draft, not law. The Oireachtas, Ireland's parliament, still has to pass it, and the Minister has to bring it into force by order. Until then the rules above apply. One tightening is already in force: since 8 December 2025 refugees wait 5 years for naturalisation instead of 3, while applications received earlier are processed under the old rule.

Irish citizenship: rules by country of origin

A Russian passport does not close the door to Ireland. Since 2022 the country has issued 14,247 visas to Russian citizens and refused only 465, according to Department of Justice figures. Most, 11,548, were short-stay visas of up to 90 days; about 2,700 were long-stay visas for work or study.

Single-entry visas. Russian passports need a visa to enter, and under European Union restrictions visas are issued for a single entry, so every trip needs a new application. Citizenship by birth for a child is realistic only after 3 years in the country on a work or family permission, which means relocating. The Foreign Births Register route is open to any nationality: there is no bar for Russians with an Irish-born grandparent. Ireland allows dual citizenship, while Russia requires its citizens to notify the Interior Ministry of a second passport within 60 days, or within 60 days of entering Russia for those living abroad; details are in our guide to dual citizenship in 2026.

Visa-free entry and temporary protection. Entry to Ireland on a Ukrainian passport is visa-free for up to 90 days. Temporary protection has been extended to 4 March 2028 by European Union Council Implementing Decision 2026/1912, which Ireland applies. Since 5 August 2026 new applicants must show they left Ukraine lawfully; people who already hold protection are not affected. For a child's citizenship by birth, current law does not exclude temporary protection, but the Passport Service asks parents with this kind of protection to contact it before applying, as requirements may differ. If the 2026 bill passes as drafted, years on temporary protection will stop counting both for naturalisation and for children born after the law takes effect.

A Ukrainian building a life in Ireland is safer moving to an employment permit early, if that option exists: those years count under any version of the rules.

What does an Irish passport give you?

The Irish passport opens 186 destinations without a prior visa, the same as the passports of Germany, France, Italy, Spain and six other countries. The British passport gives 184. The full ranking is in our 2026 passport ranking.

• European Union citizenship. The right to live, work, study and do business in any European Union country, the EEA and Switzerland without permits.
• The United Kingdom. The Common Travel Area between Ireland and the United Kingdom lets Irish citizens live, work and study in the United Kingdom without a visa or permit. No other European Union passport offers that.
• Passing it on. Children of an Irish citizen born on the island are citizens from birth wherever they are born. Children born abroad to people who became Irish through the register or naturalisation need a Foreign Births Register entry.

Living in the country also means Irish tax residence. How taxes work for newcomers is covered on our page on taxes in Ireland.

Pitfalls: who the Irish route will not work for

The biggest trap is birth tourism: flying into Dublin, giving birth and leaving with an Irish passport has not worked since 2005. The route also fails several other groups.

• People who come to give birth on a tourist visa. The child gets no citizenship, and the birth is not free for non-residents.
• Students and asylum seekers awaiting a decision. Those years count neither for the child nor for your own naturalisation.
• Great-grandchildren whose parent missed the register, and anyone whose link runs through a great-great-grandparent, uncle or cousin. Only discretionary naturalisation on Irish associations remains.
• Anyone who needs a fast passport for the parents. At least 5 years in the country, and the 2026 bill proposes 8.
• Anyone with messy paperwork. The register accepts only original civil certificates, and names along the whole chain must match or be linked by change of name documents.
• Parents who do not live with their Irish child. Stamp 4 under Zambrano requires the child to live in Ireland full time and the parent to be involved in the child's life.

How we help

We start by checking entitlement: from certificates and your permission history we work out whether you have a claim by birth, through the register or only through naturalisation, and tell you plainly if you have none. Then we assemble the document chain, order Irish and foreign certificates, handle translations and apostilles, and prepare the Foreign Births Register file or the child's passport application. Legal representation before authorities is handled by Murblz specialists together with partners licensed locally.

For day-to-day life in the country, a personal account in Ireland helps. A country overview is on the Ireland page, and every route to an Irish passport in one piece is in our article on Irish citizenship in 2026.
