5 years of reckonable residence
- • Critical Skills Employment Permit holders may apply for a Stamp 4 support letter after 21 months of employment. Naturalisation needs 5 years of reckonable residence.
- • Stamp 4: eligible after 21 months of qualifying employment.
- • Naturalisation counts only RECKONABLE residence — Stamp 1 and Stamp 4 count; student Stamp 2 and Stamp 0 do not. The final year before applying must be continuous (no more than about 70 days absent, 100 in exceptional cases).
- • You must also be of good character and satisfy the Minister; the decision is discretionary. These are indicative planning dates only - confirm with the official ISD guide, Naturalisation Residency Calculator and Citizens Information before relying on a date.
Dated verdict context
Ireland citizenship and Stamp 4 verdict context
Verified 2026-07-04
The calculator result should be read as route-clock arithmetic over ISD guidance: Critical Skills Stamp 4 after 21 months, General Employment Stamp 4 after 57 months, standard naturalisation after 5 years reckonable residence, Irish-citizen spouse/civil-partner naturalisation after 3 years, and current refugee/stateless naturalisation on a 5-year clock.
A generated date is not an ISD or Minister for Justice decision. Reckonable residence, continuous final-year residence, the 70/30 absence rule, proof scorecards, good character, joint spouse evidence and ministerial discretion still control the outcome.
Critical Skills Stamp 4 clock
21 months
ISD says Critical Skills Employment Permit holders can be eligible for a Stamp 4 permission after 21 months from commencement of employment in the State.
General Employment Stamp 4 clock
57 months
ISD says General Employment Permit and Intra-Company Transfer Employment cases can be eligible for Stamp 4 after 57 months from commencement of employment in the State.
Standard naturalisation residence clock
5 years in the last 9
ISD lists 5 years of legal/reckonable residence in the last 9 years, including 1 full year of continuous residence immediately before applying.
Final-year absence rule
70 days plus possible 30 exceptional days
ISD says the final 12 months normally allows no more than 70 days outside Ireland; an extra 30 days may be allowed for rare, severe or unavoidable events, but over 100 days is ineligible.
Irish-citizen spouse or civil partner clock
3 years
ISD lists 3 years reckonable residence on the island of Ireland, 3 years married or in civil partnership, and a continuous final year for spouse/civil-partner naturalisation cases.
Refugee/stateless current clock
5 years from grant of status
Current ISD guidance says refugees/stateless people need 5 years of reckonable residency from grant of status; applications received before 8 December 2025 continue under the previous 3-year rule.

Dates are produced by the calculator above from the published periods. They assume continuous, reckonable residence within the absence limits — they do not by themselves grant Stamp 4 or citizenship.
About this calculator
Ireland’s path runs from an employment permit (Stamp 1), to long-term residence (Stamp 4), to citizenship by naturalisation. Critical Skills permit holders can move to Stamp 4 after 21 months; General Employment permit holders after 57 months. Naturalisation usually needs 5 years of reckonable residence, with a 3-year route for the spouse or civil partner of an Irish citizen and a current 5-year clock for refugees/stateless people, including a continuous final year. This tool does the date arithmetic over those periods; it does not assess which stamps are reckonable, your absences, or good character.
Calculator provenance
- Rule review date
- 4 July 2026
- Calculation method
- Adds the published Stamp 4 and naturalisation residence periods to the reckonable-residence start date.
Primary source
It does not audit which permissions are reckonable, absence totals, continuous final-year residence, good character, or ministerial discretion. This independent calculator is for planning only; the authoritative result is the relevant government or caseworker decision.
FAQs
When can I apply for Irish citizenship by naturalisation?
After 5 years (1,825 days) of reckonable residence out of the last 9 years, including 1 continuous year immediately before you apply. The spouse or civil partner of an Irish citizen can apply after 3 years. Current ISD guidance uses 5 years for refugees/stateless people, with the previous 3-year rule continuing for applications received before 8 December 2025.
How long until I can get Stamp 4?
Critical Skills Employment Permit holders can apply for a Stamp 4 support letter after 21 months of employment. General Employment Permit holders can apply after 57 months. Some routes (spouse of an Irish citizen, refugees) hold Stamp 4 already.
What counts as reckonable residence?
Time on Stamp 1 (employment permit) and Stamp 4 counts towards naturalisation. Student time on Stamp 2 and time on Stamp 0 do not count. The final year before you apply must be continuous, with no more than about 70 days outside Ireland (100 in exceptional circumstances).
Does this calculator confirm I will get citizenship?
No. It is date arithmetic over the published residence periods, not a decision. Naturalisation also requires good character and is granted at the Minister’s discretion. Always confirm with the official Naturalisation Residency Calculator and Citizens Information.
