What is this right?
There are two main routes to Irish citizenship for people not Irish at birth: naturalisation (residence-based) under the Irish Nationality and Citizenship Act 1956 and citizenship by descent (Foreign Births Register) for people with an Irish-born grandparent or great-grandparent.
Naturalisation: Non-Irish nationals apply under s.15 of the 1956 Act after 5 years of reckonable residence in the 9 years before application, including a continuous 12 months immediately before the application. Spouses/civil partners of Irish citizens apply under s.15A after 3 years of reckonable residence and 3 years of marriage/partnership. International protection beneficiaries who apply on or after 8 December 2025 now need 5 years instead of 3 (earlier applications remain under the 3-year rule). Since the Courts and Civil Law (Miscellaneous Provisions) Act 2023 (commenced 31 July 2023), the continuous-residence year allows up to 70 days absence, with a further 30 days in exceptional circumstances. Applications are made online (portal launched 16 October 2023). Fees: €175 application + €950 certification (adult standard); €200 for minors, widows/widowers, surviving civil partners; free for refugees and stateless persons. Current median processing time is about 19 months. The revocation regime under s.19 was reinstated 7 April 2025 after the Supreme Court's Damache decision struck down the prior process.
Citizenship by descent (Foreign Births Register): If you were born outside Ireland and have at least one Irish-born grandparent, you are entitled to Irish citizenship under s.7 of the 1956 Act by registering on the Foreign Births Register (FBR) at foreignbirths.ie. The grandparent rule extends one further generation: if your parent was registered on the FBR before your birth, you are also entitled (great-grandchild route). FBR registration must be completed in your parent's lifetime to pass it on to your own children — under s.7(3), a parent must be registered before the child's birth for the child to claim. Current FBR processing time is approximately 12 months (DFA, 2026). Fee: €278 for adults / €153 for minors. Once registered, you become an Irish citizen from the date of entry on the Register and may apply for an Irish passport.
When does it apply?
This applies when:
- You have reckonable residence of 5 years (3 years for spouses/civil partners of Irish citizens, with 3 years of marriage/partnership) and the continuous year immediately before applying
- You are an international protection beneficiary applying on or after 8 December 2025 (5-year rule) or earlier (3-year rule)
- You are the parent of an Irish-born child aged under 18 and not entitled at birth (Form 11 — 3-year rule post-2023)
- You claim citizenship by descent via the Foreign Births Register: at least one Irish-born grandparent (4-generation rule extends through a parent who registered on the FBR before your birth)
Spouse/civil partner route (s.15A): 3 years of reckonable residence in the 5 years before application, 3 years of marriage or civil partnership, spouses living together, both signing the statutory declaration on the Form 8.
Requirements:
- Reckonable stamps: 1, 1G, 3, 4, 5. Not reckonable: Stamp 2/2A (student permission — generally non-reckonable per ISD guidance), AWS, undocumented time, international-protection-applicant time (but Stamp 4 after grant is reckonable). Verify borderline periods using the ISD residency calculator before counting them.
- Continuous year absences (post-31 July 2023): up to 70 days; further 30 days in exceptional circumstances.
- Good character (s.15(1)(b)): Minister considers Garda report, driving offences, investigations, pending cases, cautions, and some civil matters; applicants complete e-vetting. Leading case law: Talla [2020] IECA 135; MNN [2020] IECA 187; M v Minister for Justice [2024] IEHC 105 affirmed by the Court of Appeal 7 January 2025.
- Intention to reside in the State after naturalisation.
- Declaration of fidelity at a ceremony (citizenship ceremonies administratively introduced 2011).
- 150-point identity/residence scorecard: certified colour photocopies of passport, IRP/GNIB cards, tax records, utilities, tenancy.
- Minor born in Ireland after 1 January 2005 but not Irish by birth: 3 years reckonable residence (reduced from 5 by the 2023 Act).
Revocation (s.19) — reinstated 7 April 2025. Grounds unchanged. Damache v Minister for Justice [2020] IESC 63 struck down the earlier procedure. National-security-based refusals flow to a Single Person Committee of Inquiry per P v Minister for Justice [2019] IESC 47.
Fees: €175 application + €950 adult certification (€200 minor / widow / widower / surviving civil partner / free for refugees and stateless persons).
Processing: median ~19 months per Citizens Information (page edited 16 April 2026); 12–24 months realistic.
What to Do If You Are Ready to Apply for Irish Citizenship by Naturalisation

Step 9 — Apply for an Irish passport with the certificate.
Citizenship by descent (Foreign Births Register) — separate process:
- Confirm eligibility: at least one Irish-born grandparent, OR a parent who was registered on the FBR before you were born.
- Gather originals or certified copies: your birth certificate, your parent's birth certificate, the Irish-born grandparent's Irish birth certificate (from gov.ie/General Register Office, €20), and marriage certificates where surnames have changed.
- Register online at foreignbirths.ie, upload documents, and pay €278 (adult) or €153 (minor).
- Post originals to the Department of Foreign Affairs (DFA) FBR Unit when prompted. Current processing: approximately 12 months.
- Once registered, you are an Irish citizen from the date of FBR entry. Apply for an Irish passport at passportonline.ie.
- To pass citizenship to your own future children, you must complete your own FBR registration before they are born (s.7(3)).
What should you NOT do?
Don't exceed 70 days out of Ireland in the continuous year (or 100 days with an exceptional allowance). Jones v Minister for Justice [2019] IECA 285 upheld the pre-2023 six-week policy; the 70/100-day rule is now on the statute book from 31 July 2023.
Don't count Stamp 2 / AWS / protection-applicant time. These are not reckonable. Student time is not partially counted — that earlier practice is gone under current guidance.
Don't apply with unresolved road-traffic or tax issues. Good character is a common refusal ground. M v Minister for Justice [2024] IEHC 105 (affirmed by the CoA 7 January 2025) upheld refusal for cumulative road-traffic offending; earlier Talla and MNN judgments tightened the need for holistic, exculpatory-material-weighing reasoning.
Don't rely on uncertified photocopies. The 150-point scorecard requires certified copies for identity and each residence year.
Don't skip the reasons point: since Mallak, refusals must come with reasons (or a justification for withholding them). Ask for reasons if they are not given — a judicial review is rarely successful without them.
Don't expect a statutory appeal — there isn't one. Only reapplication or judicial review.
About Immigration Pathways in Ireland
If you're applying to work or live in Ireland, the Immigration Act 2004, the Employment Permits Act 2024, and the Irish Nationality and Citizenship Act 1956 set the rules. ISD runs visas and IRP cards (€300 fee under SI 421/2025); DETE runs employment permits through EPOS. The two main work routes are the Critical Skills Employment Permit and the General Employment Permit, with MAR thresholds rising in 2026 and every permit salary needing to meet €14.15/hour. EU/EEA/Swiss nationals enter freely under SI 548/2015. Track IRP expiry — overstaying ends in a section 3 deportation notice.
Common Questions
How much absence is allowed in the Irish continuous year?
Since 31 July 2023, up to 70 days out of Ireland is permitted in the continuous 12 months immediately before the application, with a further 30 days in exceptional circumstances (total 100 days max). This was a statutory codification of the older six-week policy upheld in Jones v Minister for Justice [2019] IECA 285.
Which Irish stamps count toward naturalisation?
Reckonable stamps are 1, 1G, 3, 4, and 5. Stamp 2, Stamp 2A, AWS permissions, undocumented time, and time as an international-protection applicant are not reckonable (but Stamp 4 after a positive protection decision is). Use the ISD residency calculator at irishimmigration.ie to total the reckonable years.
How much does Irish naturalisation cost in 2026?
€175 application fee plus €950 certification fee for adults — total €1,125. Minors, widows/widowers, and surviving civil partners pay a combined €200. Refugees and stateless persons pay nothing. Current median processing time is about 19 months per Citizens Information. Approved applicants attend a citizenship ceremony and make the declaration of fidelity.
Can I claim Irish citizenship through my grandparent (Irish citizenship by descent)?
Yes. If you were born outside Ireland and at least one of your grandparents was born in Ireland, you are entitled to Irish citizenship under s.7 of the Irish Nationality and Citizenship Act 1956 by registering on the Foreign Births Register at foreignbirths.ie. The route extends one further generation (great-grandchild) only if your parent was registered on the FBR before you were born. Fees are €278 (adult) / €153 (minor) and processing currently takes about 12 months. To pass citizenship to your own children, you must register before they are born.
Does my marriage to an Irish citizen reduce the residence requirement?
Yes. Under s.15A, spouses and civil partners of Irish citizens can naturalise after 3 years of reckonable residence in the 5 years before application, with 3 years of marriage or civil partnership and the spouses living together. Both spouses must sign the statutory declaration on Form 8. The 70/100-day continuous-year absence rule and the good-character requirement still apply.
