Irish Citizenship Checker

Find the route that fits you.

Six guided checks. Each counts your days the way the official ISD calculator does, instantly, in your browser.

Citizenship by residenceYou are 18 or over and have lived in Ireland legally. The test is a day count: 5 years of reckonable residence inside the last 9, ending with one gap-free year.5 years in the last 9

Spouse of an Irish citizenYou have been married to, or in a civil partnership with, an Irish citizen for 3 years or more and you live together on the island of Ireland.3 years in the last 5

Refugee and protectionYou hold refugee status, subsidiary protection or permission to remain. Your residence clock starts the day status was granted, not the day you arrived.5 years from your grant

Irish descent or associationsYou are connected to an Irish citizen by blood, adoption, marriage or civil partnership. A discretionary route the Minister weighs on the strength of your ties.Discretionary, section 16

Applying for a childA parent or guardian applies for a child under 18: through a naturalised parent, through Irish descent, or through birth in the Republic on or after 2005.Child under 18

Birth and descentBorn on the island of Ireland, or with an Irish parent, grandparent or great-grandparent? You may already be a citizen, with no naturalisation needed.Passport or Foreign Births Register

Not sure? Start with birth and descent in case you are already a citizen. Otherwise most adults belong on residence.

An estimate on the rules last verified 18 August 2026, never a decision. Your answers stay in your browser.
