Notes and caveats

  • Student time on Stamp 2 is never reckonable for citizenship. Only time after you move onto a qualifying permission begins the clock.
  • Naturalisation needs one continuous year of residence immediately before you apply, on top of the five-year total.
  • The five years of reckonable residence must fall within the nine years before you apply.
  • Naturalisation is at the Minister's absolute discretion. Meeting the residence conditions makes you eligible to apply; it does not entitle you to a grant.

Common questions

How long until I can naturalise in Ireland?
Naturalisation by residence generally requires five years of reckonable residence in the nine years before applying, with the final year continuous. The calculator projects that date from what you enter; it does not judge which of your years are reckonable, and not every permission counts.
What does reckonable residence mean?
Time held on certain permissions counts and time held on others does not — student permission is the usual surprise. Immigration Service Delivery publishes which stamps are reckonable, and that determination is theirs, not this calculator's.
Where is this from?
The naturalisation guidance published by Immigration Service Delivery, Department of Justice, read on 15 August 2026. The link above is that page.
