Congratulations! You are Eligible to Apply for Irish Citizenship

If your answer to all of the above is "Yes", you have the right to claim Irish Citizenship.
You make your claim by registering your birth on Ireland's Foreign Birth Register. You become an Irish citizen once your birth is registered, and you are free to apply for your first Irish passport.
You are also free to live, study, work and retire to Ireland or any other country in the European Union.

Eligibility Scenarios in cases of Legal Adoption outside of Ireland

I was born outside of Ireland and adopted by non-Irish citizens. My biological parent was an Irish citizen

If your biological parent was born in Ireland, you are already an Irish citizen and entitled to apply for an Irish passport at any time. If your biological parent was born abroad, but your biological grandparent was born in Ireland, you must first apply to the FBR to register your birth. You can then apply for an Irish passport at any time. 

For foreign adoptions to confer Irish citizenship they must be registered in the Register of Intercountry Adoptions by the Adoption Authority of Ireland.  Once your legal adoption is registered, you are an Irish citizen and able to apply for an Irish passport at any time. This applies even if you were adopted by an Irish citizen who was also born outside of Ireland.  (See Section 11 Irish Nationality and Citizenship Act 1956, as amended)

In order for you to claim Irish citizenship, your parent’s adoption by Irish citizens would have to be recognised in Irish law by registering it in the Register of Intercountry Adoptions by the Adoption Authority of Ireland. You will then be an Irish citizen and able to apply for an Irish passport at any time. 

You are the grandchild of an Irish citizen, regardless of where your grandparent was born. You are entitled to apply to have your birth registered on Ireland’s Foreign Birth Register. Once registered, you are free to apply for a passport at any time. 

As you are the third consecutive generation born outside of Ireland, and your grandfather was not adopted by Irish citizens, you are not entitled to apply to have your birth registered on the FBR unless your parent had applied to have their own birth registered on the FBR before you were born.  If your parent did register their birth on the FBR before you were born, they were an Irish citizen when you were born and you are entitled to apply based on their FBR registration. 

Preserve your descendants rights to claim Irish citizenship by registering your birth on the Foreign birth Register before your children are born

As the grandchild of the last Irish born generation of your family, it is up to you to ensure the right to Irish citizenship does not end with you. Preserve the right to Irish citizenship for your children, by registering your birth on the Foreign Birth Register BEFORE your children are born.  They can exercise their right to claim Irish citizenship thanks to your Foreign Birth Registration (FBR). If your children were born AFTER you registered on the FBR, click here to find out how we could help them apply for Irish citizenship through Naturalisation.

We will help you prepare all remaining documents you will need to submit in support of a successful application.

I cannot express enough gratitude for the incredible work Des did in uncovering details about my Irish grandmother—information that had long been lost to time and family memory. For years, I had hit brick wall after brick wall in my own research. I scoured every online archive I could find, followed countless false leads, and began to think I might never truly know her story. Then I found Des. From our very first conversation, it was clear I was in the hands of someone deeply knowledgeable, endlessly patient, and genuinely passionate about Irish genealogy. Des took the time to understand what I already knew, what I was hoping to discover, and why it meant so much to me. He approached my search not just with expertise, but with empathy. In what felt like no time at all, Des had traced records I didn’t even know existed—church documents, land registries, local archives—and pieced together a narrative that brought my grandmother’s early life in Ireland into vivid focus. He even uncovered the tragic death of my great-grandmother and articles relating to the family’s attempt to sue for compensation in 1913! What Des gave me was more than names and dates—he gave me a sense of belonging, a deeper understanding of my roots, and a connection to a past that had felt just out of reach. It's something truly priceless. If you're looking for someone who is not only incredibly skilled but also deeply committed to helping people reconnect with their heritage, I cannot recommend Des highly enough. His work has been a gift to me and my family, and we’ll forever be grateful. Thank you, Des—from the bottom of my heart.
