1. What is Irish Naturalisation?

Irish naturalisation is the process by which a foreign national can become an Irish citizen. The primary requirement is having at least 5 years of legal residency in Ireland.

2. How Does the Calculator Work?

The calculator uses the simple eligibility formula:

Where:

• residency — Years of continuous legal residence in Ireland

Explanation: You must have been legally resident in Ireland for at least 5 years (1825 or 1826 days) out of the last 9 years, including 1 year of continuous residence immediately before the application.

3. Importance of Residency Requirement

Details: The 5-year residency requirement is the most fundamental criterion for naturalisation. Other requirements include good character and intention to continue residing in Ireland.
