The short answer
- Most adults: 1 year of continuous residence right before you apply, plus 4 years in the 8 before that: 5 years in 9.
- Spouses and civil partners of Irish citizens: 1 year plus 2 in the 4 before, on the island of Ireland.
- Counts: Stamps 0, 1, 1G, 3, 4 and 5, and protection status once granted.
- Doesn’t count: Stamp 2 and 2A, gaps in permission, and time waiting for a protection decision.
- Refugees, EU citizens, young adults and children each have their own version.

Your rule, and whether your time in Ireland counts.
To register for the first time
From the Irish Nationality and Citizenship Act 1956 (sections 15, 15A, 16 and 16A, as amended) and ISD’s citizenship guide. Nothing you choose is sent or saved. To count your own dates, use the citizenship clock.
What counts and what doesn’t
| Time in Ireland | Counts? |
|---|---|
| Stamp 1: employment permits, researchers, business | Yes |
| Stamp 1G: graduates, and partners of Critical Skills permit holders or researchers | Yes. Other partners: ask ISD |
| Stamp 3: dependants | Yes |
| Stamp 4, Stamp 5, Stamp 6 | Yes |
| Stamp 0 | Yes, ISD says |
| Refugee status, subsidiary protection, permission to remain | Yes, from the grant |
| Stamp 2 and 2A: students | No, except some young adults at the Minister’s discretion |
| Waiting for a protection decision | No |
| Any time without permission, however short | No |
| Diplomatic postings | No |
Add every reckonable period together, whatever the stamp. To count your own dates, use the citizenship clock and the 5-in-9 window explorer.
The rule, route by route
| How you’re applying | Residence you need |
|---|---|
| Adult | 1 year continuous before you apply, plus 4 in the 8 years before that |
| Spouse or civil partner of an Irish citizen | 1 year continuous on the island of Ireland, plus 2 there in the 4 before. Married or civil partners for 3 years, living together |
| Refugee or international protection | Generally 1 year plus 4, counted from your grant, for applications from 8 December 2025. Before that, 3 years. The Minister can waive conditions |
| EU, EEA, Swiss or UK citizen | The same 5 in 9, shown with documents rather than permission dates, if you’ve held your nationality for more than 5 years |
| Young adult, 18 to 23 | The adult rule. If you came as a child, depend on your parents and went to school here, some Stamp 2 time may count |
| Child born in Ireland since 2005 | 3 years since birth: 1 continuous year, plus 2 in the 8 before. Northern Ireland doesn’t count |
| Child of a naturalised parent, or Irish descent | No fixed period: the Minister can waive the conditions |
The continuous year
Count back from the day you apply. The year immediately before must be unbroken residence: 365 days, or 366 if it includes a 29 February. ISD’s calculator then looks for 1,460 more days (plus any leap days) in the 8 years before that.
Unbroken doesn’t mean you can’t travel. In the same year you can be away up to 70 days, plus 30 for exceptional circumstances.
Students and young adults
Time on Stamp 2 or 2A never counts for most people: the Act excludes residence on a permission to study. For most graduates, the clock starts with Stamp 1G.
Young adults aged 18 to 23 who came to Ireland legally as children, depend on their parents for accommodation and living costs, and went to school here, or straight from school to college, may have some student time counted, at the Minister’s discretion. A school or college letter can be one of their residence proofs.
Protection: time starts at the grant
Time spent as an international protection applicant, including in Direct Provision or IPAS accommodation, doesn’t count. Your reckonable residence starts the day you’re granted refugee status, subsidiary protection or permission to remain. ISD’s residency calculator doesn’t work for refugees.
Northern Ireland
Only the spouse and civil partner route is about the island of Ireland. On every other route, the Act counts residence in the State only, so time living in Northern Ireland doesn’t count, and for a child born in Ireland since 2005, residence in Northern Ireland doesn’t count either.
Common mix-ups
Common questions
What is reckonable residence?
Time living in Ireland that counts towards naturalisation. Residence with a permission like Stamp 1, 1G, 3, 4 or 5 counts. Time without permission, on a student permission or as a protection applicant doesn't.
Does Stamp 2 count towards citizenship?
No. The Citizenship Act excludes residence on a permission to study, so Stamp 2 and 2A don't count. ISD's one exception: young adults who came as children and stayed in education here may have some student time counted at the Minister's discretion.
Does Stamp 3 count?
Yes. ISD's guide lists Stamp 3, as the dependant of someone with a qualifying permission, as reckonable.
Does a gap in my permission break my residence?
The gap itself doesn't count, and ISD warns that even short gaps can make an application ineligible, not just delayed. For the final year before you apply, it must be continuous.
Does time as an asylum seeker count?
No. Only time after you're granted refugee status, subsidiary protection or permission to remain counts. Since 8 December 2025, people granted protection generally need 5 years from then.
Does living in Northern Ireland count?
Only for spouses and civil partners of Irish citizens, whose rule is about the island of Ireland. For everyone else, only residence in the State counts.
Is the continuous year exactly 12 months?
Count back from the day you apply: 365 days, or 366 if a 29 February falls in it. You can still travel: up to 70 days away, plus 30 for exceptional circumstances, without breaking it.
