Irish Citizenship by Naturalisation
Naturalisation support for applicants who need a careful review of residence history, identity proofs, yearly residence evidence, absence records and route-specific citizenship documents.
Citizenship preparation
Build a naturalisation file that is clear year by year.
Naturalisation is not just a form. The application depends on route, residence history, identity evidence, yearly residence proofs, absences and discretion. i2i reviews the practical file before the official online application is prepared.
Official guidance
Irish citizenship rules, fees and document requirements can change. These links should be checked before final submission.
i2i preparation
What i2i does for naturalisation
We turn scattered immigration, tax, address and travel records into a structured application pack. The aim is to make the applicant's residence history understandable, the scorecard evidence complete and the supporting documents easy to review.
Current rules to check first
Standard adult route
Most adult applicants need 5 years of reckonable residence in the previous 9 years, including 1 year of continuous residence immediately before applying.
Final-year absence check
The final year before application needs careful review. ISD guidance uses strict absence limits, so travel days should be calculated before choosing a submission date.
Online submission
The naturalisation application is made online. Once submitted, the application cannot be edited in the same way as a draft intake.
Proposed changes
Reported 2026 proposals include longer residence, language, civics and economic self-sufficiency requirements. These are treated as proposed until enacted.
