    Who is eligible for Irish citizenship by birth?

    According to Irish law, if you were born in Ireland before 1 January 2005, you are eligible for Irish citizenship by birth. Similarly, if you were born in Northern Ireland before 1 January 2005, you can choose to claim citizenship as well. However, in 2004, the people of Ireland voted to change the law granting Irish citizenship by birth to everyone born in Ireland.

    This is why if you were born on the island of Ireland after 31 December 2004, whether or not you are entitled to Irish citizenship depends on the nationality or residence history of your parents and grandparents.

    If you were born to an Irish citizen parent or a British citizen parent, you can become an Irish citizen by birth in the following circumstances:

    • Either of your parents was an Irish or UK citizen at the time of your birth and you were born in Ireland
    • Either of your parents was an Irish or UK citizen at the time of your birth and you were born in Northern Ireland (then you can choose to claim your Irish citizenship)
    • Either of your parents was an Irish or UK citizen but died before you were born.

    If you were born on the island of Ireland on or after 1 January 2005 to a parent who was not an Irish or UK citizen, you can become an Irish citizen by birth in the following circumstances:

    • One of your parents has lived in Ireland or Northern Ireland for 3 out of the 4 years before you were born
    • One of your parents had the right to live in Ireland or Northern Ireland without any restrictions at the time of your birth

    Irish citizenship by birth to children born abroad

    If you were born outside of Ireland but either of your parents was an Irish citizen at the time of your birth, you are automatically an Irish citizen by birth. If the parent who was supposed to pass their Irish citizenship to you was deceased at the time of your birth but would have been an Irish citizen if they had been alive then, you are also an Irish citizen by birth.

    These rules apply even if your parent was not born in Ireland themselves but obtained Irish citizenship later on.

    To claim your Irish citizenship by birth, you need to have your birth registered in the Foreign Birth Registration. If you are eligible for Irish citizenship by birth, your Irish citizenship is effective from the registration date rather than from the date when you were born.

    Who is eligible for Irish citizenship by descent?

    Irish citizenship by descent is the process of obtaining Irish citizenship based on the principle of one of your older relatives having had Irish citizenship, or having been born in Ireland.

    This will normally apply to those who were born outside Ireland who have parents or grandparents who meet the eligibility criteria for citizenship.

    Note that cases of “extended previous ancestry”; that is, Irish ancestry that extends beyond parents or grandparents are not normally eligible to claim Irish citizenship by descent.

    You may, however, be able to claim  citizenship based on Irish associations, as long as you meet all the necessary eligibility criteria.

    Requirements for Irish citizenship by descent

    The specific eligibility for Irish citizenship by descent depends on when where and when you were born, as well as the status of your parents and/or grandparents at the time of your birth.

    For example, those born outside of Ireland whose grandparent is an Irish citizen born in Ireland and whose parent is an Irish citizen born outside of Ireland is entitled to Irish citizenship via registering on the Foreign Births Register.

    Once your details are entered into the register, you will officially become an Irish citizen and you will be able to get your Irish passport.

    Note that in order to apply for citizenship through descent or associations, you must consider the following requirements:

    • It is expected that you should have been living in Ireland for at least 3 years to demonstrate a connection to Ireland
    • Citizenship by descent applications going further back than great-grandparents are generally not eligible
    • Citizenship applications on the basis of ascent (being the parent or grandparent of an Irish citizen) or on the basis of brother or sisters are generally not eligible

    Cost of Irish citizenship by descent or birth

    How much it costs to apply for citizenship generally depends on your chosen route.

    Generally speaking, there is a cost of €175 for applications for citizenship by naturalisation (with an additional fee afterwards to obtain your certificate of naturalisation). If you’re applying for citizenship by descent, you will need to pay €278 to register a birth on the Foreign Births Register.

    A standard adult Irish passport costs €75 to obtain.

    Individuals born to an Irish citizen who are themselves eligible for Irish citizenship by birth will not have to pay a fee to apply for citizenship; this is because the individual is already considered to be an Irish citizen and therefore no additional application needs to be made.

      Can adopted children become Irish citizens?

      If a child who is not an Irish citizen is adopted by an Irish citizen or a couple where at least one person is an Irish citizen, the adopted child becomes an Irish citizen too through Irish associations.

      When an Irish citizen living abroad decides to adopt a child there, they need to apply for the adoption to be entered in the Register of Intercountry Adoptions. After they do that, the adoption will have the same status as adoptions made in Ireland. That means that the adopted child will become an Irish citizen.

      In a situation where an Irish citizen living in Ireland is waiting for adoption made abroad to be recognized in Ireland, they need to get immigration clearance from the Department of Justice to be able to bring the adopted child into the state. The clearance will be given to adoptive parents only after they complete the assessment procedure and receive a declaration from the Adoption Authority of Ireland.

      What is Irish citizenship through a special declaration?

      Some people might be able to claim Irish citizenship by making a declaration. To be eligible for this route towards Irish citizenship, one of the following has to apply to your situation:

      • You were born in Ireland between 2 December 1999 and 31 December 2004 to a foreign national who, at the time of your birth, had the right to diplomatic immunity in Ireland (for example ambassadors of foreign countries)
      • You were born between 2 December 1999 and 31 December 2004 in the Irish sea or Irish air space to a foreign national on a foreign ship or aircraft
      • You were born in Ireland and you made a declaration of alienage under Section 21 of the Irish Nationality and Citizenship Act 1956. That means that you made a declaration stating that you are no longer an Irish citizen. In such circumstances, you have the right to resume your Irish citizenship by making a special declaration.

      Get in touch with our lawyers and they can help you determine whether you can get Irish citizenship through a special declaration.
