Apply for Irish Citizenship by Naturalisation

To be eligible to apply based on residence, you must:

• Be 18 years of age or older
• Be able to prove your identity
• Have met the residency requirements
• Have lived continuously in Ireland for one full year immediately before applying (you may be absent for up to 70 days, or up to 100 days in exceptional circumstances at the Minister’s discretion)
• Have accumulated a total of four years of residence in Ireland within the eight years prior to that one-year continuous period
• Provide proof of residence for every year claimed — usually in the form of household bills, tenancy or mortgage agreements, or similar official documents
• Intend to reside in Ireland permanently after becoming a citizen
• Be of good character
• Be willing to attend a citizenship ceremony and make a declaration of fidelity
• Provide three Irish Citizen references, granting permission for the Citizenship Division to contact them

If you have lived abroad for extended periods while holding permission to reside in Ireland, you must submit detailed supporting information with your application.

Maintaining an up-to-date Irish Residence Permit (IRP) is essential, as unexplained gaps in your residency record may result in your application being refused.

Applying as a Dependant Young Adult

A dependant young adult is a person who relies on their parents for accommodation and daily living costs. You may apply as a dependant young adult if you meet the standard eligibility criteria and:

• Are aged between 18 and 23
• Entered Ireland legally as part of a family unit
• Are currently attending secondary school or have moved directly from secondary to third-level education in Ireland
• Are financially dependent on your parents

If you are married to or in a civil partnership with an Irish citizen, you may apply for citizenship through this route. To qualify, you must:

• Be 18 years of age or older
• Prove your identity
• Have been married to or in a civil partnership with an Irish citizen for at least three years
• Demonstrate that your relationship is genuine and ongoing
• Be living together with your spouse or partner at the time of application and when citizenship is granted
• Have resided legally in Ireland for three of the previous five years, including one full year of continuous residence immediately before applying (up to 70 days of absence are permitted, or 100 in exceptional cases)
• Provide proof of residence for each year claimed
• Intend to continue residing in Ireland after becoming a citizen
• Be of good character
• Be willing to attend a citizenship ceremony and make a declaration of fidelity

In addition to your own documentation, you must also provide proof of residence for your Irish spouse or partner, as outlined in the Citizenship Guidance Document.

If you have been granted refugee status in Ireland, you may apply for citizenship through naturalisation. To qualify, you must:

• People granted International Protection must generally have five years of reckonable residence in the State before they can apply for citizenship. This is effective from 8th December 2025.
• Be 18 years of age or older

• Hold an official declaration of refugee status from the Minister for Justice
• Be able to prove your identity (special provisions apply as detailed in the Citizenship Guidance Document)
• Have resided in Ireland for at least three years
• Ensure your immigration permission remains valid and continuous, as gaps may affect eligibility

A minor is a child under 18 who is not married. A child cannot apply for citizenship on their own — the application must be made by a parent, legal guardian, or a person acting in loco parentis.

Applications on behalf of a minor may be made in the following cases:

1. By a naturalised parent on behalf of their child
2. On behalf of a child of Irish descent or Irish associations
3. On behalf of a child born in Ireland on or after 1 January 2005, who is not entitled to citizenship by birth but meets the residence requirements for naturalisation

The Minister for Justice has absolute discretion to waive normal requirements in certain cases involving Irish associations, defined as relationships by blood, affinity, or adoption.

As of 2 April 2025, updated guidelines outline how applications are assessed under Section 16(1)(a) and 16(1)(b) of the Irish Nationality and Citizenship Act 1956 (as amended). Applications are scored across four key areas:

• Family connection to the State
• Cultural connection
• Experiential connection
• Establishment in the State

Applicants must achieve at least 50% or more in two or more categories to qualify. However, meeting the scoring threshold does not guarantee approval, as all decisions remain at the Minister’s discretion.
