The short answer
- Born before 2005 on the island of Ireland: Irish, or entitled to be.
- Born since 1 January 2005: Irish from birth if, on the day of the birth, one parent was:
- an Irish or British citizen;
- entitled to live in Ireland or Northern Ireland without a time limit, like Stamp 5; or
- resident for 3 of the 4 years before the birth, counting only reckonable residence.
- Otherwise: the child can be naturalised after 3 years.
- Proof: the child’s first Irish passport, with the qualifying parent’s documents.

What the Passport Service asks for
Worked out in your browser: nothing you enter is sent to us or saved. From the Citizenship Act (sections 6, 6A and 6B), Citizens Information and the Passport Service. The Passport Service decides when you apply for your child’s passport.
The 3 out of 4 years
If neither parent was Irish or British, or entitled to live here without a time limit, look at each parent’s residence in the 4 years immediately before the birth. One of them needs at least 3 years in total, in one block or several, on the island of Ireland.
| Counts | Doesn’t count |
|---|---|
| Stamps 1, 1G, 3 and 4 | Stamp 2 and 2A (study) |
| Living here as an EU, EEA or Swiss citizen | Waiting for a protection decision |
| Refugee status or subsidiary protection, from the grant | Any time without permission |
| Legal residence in Northern Ireland | A diplomatic posting |
The dates on your IRP cards are the evidence, so gaps between permissions matter here too.
Proving it: your child’s first passport
You show your child is Irish by applying for an Irish passport. As well as the child’s full civil birth certificate, with the parents’ names, the Passport Service asks for the qualifying parent’s documents:
| The parent at the birth | What the Passport Service asks for |
|---|---|
| Irish citizen | A copy of their Irish passport issued before the birth, or their Irish birth, naturalisation, Foreign Birth Registration or post-nuptial certificate |
| British citizen | Their original British passport issued before the birth, or their birth certificate if born on the island of Ireland |
| EU, EEA or Swiss citizen | Their ID card or passport, proof of residence for 3 of the 4 years (such as tax records with at least 35 weeks’ insurable employment a year), and Declaration Form A |
| Refugee or subsidiary protection | The protection declaration, their passport or travel document, and IRP cards covering 3 of the 4 years |
| Another permission | Their passport showing permission stamps for 3 of the 4 years, their IRP cards, and a signed summary of each permission |
The Passport Service returns original documents within 20 working days of the passport issuing. Don’t book travel until you have it.
Not Irish from birth? Naturalisation
A child born here since 2005 who isn’t a citizen can be naturalised once they have 3 years’ reckonable residence: 1 unbroken year before you apply, plus 2 in the 8 years before that. Residence in Northern Ireland doesn’t count for this.
- A parent or guardian applies, with the child’s passport and birth certificate, school letters and 150 points of residence proof for each year.
- The application fee is €175, and the certification fee for a child is €200.
- If a parent becomes a naturalised Irish citizen, they can apply for their child, and the Minister can waive the residence conditions.
Common mix-ups
Common questions
Is a baby born in Ireland automatically an Irish citizen?
Not since 1 January 2005. The child is Irish from birth only if, on the day of the birth, a parent was Irish or British, was entitled to live in Ireland or Northern Ireland without a time limit, or had at least 3 years' reckonable residence on the island of Ireland in the 4 years before the birth.
What counts towards the 3 out of 4 years?
Legal residence, such as time on Stamps 1, 1G, 3 and 4, or living here as an EU, EEA or Swiss citizen, or with refugee status or subsidiary protection. Time as a student, waiting for a protection decision or without permission doesn't count.
Does Stamp 4 count as having no time limit?
Stamp 4 has an expiry date, so a parent on Stamp 4 normally relies on the 3-in-4-year rule instead. Stamp 5 is permission without condition as to time.
How do I prove my child is Irish?
By applying for an Irish passport for them. The Passport Service asks for the child's birth certificate and the qualifying parent's documents, such as their passport, IRP cards and a summary of their permissions.
My child isn't an Irish citizen. What now?
You can apply for naturalisation for them once they have 3 years' reckonable residence: 1 unbroken year before you apply, plus 2 in the 8 years before that. Residence in Northern Ireland doesn't count for this. The certification fee for a child is €200.
Does a child born in Ireland need an IRP?
No. The registration section of the Immigration Act 2004 doesn't apply to anyone born in Ireland, at any age, whether or not they're a citizen.
