Naturalisation is generally available under the '5 in 9' rule: five years of reckonable residence in the last nine, including one continuous year immediately before applying, plus good character. Ireland permits dual citizenship.
Non-EEA nationals with enough reckonable residence can apply to the Minister for Justice for naturalisation. The general rule is '5 in 9': five years of reckonable residence in the last nine, including one continuous year immediately before applying, together with good character and an intention to continue living in Ireland. Applications are made to Immigration Service Delivery.
The definition of reckonable residence is central. It mainly covers time on Stamp 1 (employment-permit work), Stamp 4 or Stamp 5 — student and graduate time on Stamp 2 or Stamp 1G does not count toward the five years. This is why graduates often find their qualifying clock effectively starts once they move onto a Stamp 1 or Stamp 4 permission. Helpfully, Ireland permits dual citizenship, so you usually need not give up your existing nationality.
Because the residence calculation is exacting and the rules can change, confirm the current position on irishimmigration.ie before applying. ACME can review your residence history, work out when you become eligible, and help prepare a complete naturalisation application.
