Irish Citizenship

Becoming an Irish citizen through naturalisation

Naturalisation is the process whereby a non-national can become an Irish citizen. Find out more about who is eligible to become an Irish citizen through naturalisation and how to apply for naturalisation.

Irish citizenship through birth or descent

You are not automatically an Irish citizen if you were born on the island of Ireland. You may be entitled to Irish citizenship if your parent(s) or grandparents were Irish. You may be entitled to Irish citizenship if you were born outside of Ireland, but you may need to register your birth.

Becoming an Irish citizen through marriage

If you are a non-Irish national who is married to an Irish citizen, you may be able to become an Irish citizen if you fulfil certain conditions.
