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.

How Our Research Works

Step 1 - Submit Your Ancestor's Details

Tell us as much information about your Irish born grandparent by completing our online form. Names, dates, maiden names, siblings, great grandparents names, locations, dates of emigration, employment, places and dates of birth, marriage and death, facts and anecdotes. Tell us what you know and let us use it to pinpoint your Irish family.

Step 2 - Free Consultation & Initial Research

Unlike our competitors, we do not charge initial consultation fees. As part of our Free Consultation process, and based on the information you have provided, we will undertake initial research to determine whether we can assist you. The more information you provide, the greater the chance of success. If we find we can't help you, we will tell you for free.

Step 3 - You Commission Creeore

If you wish to commission Creeore, we will invoice you 50% of our fee (€375 - 50% of €750) plus the cost of acquiring the required certified certificates of birth, marriage and death. Certificate costs vary per jurisdiction but Irish certificates cost €23 including postage. We will help you prepare all remaining documents you will need to submit in support of a successful application.

Step 4 - Submission of Online Application & Documentation

When we have obtained all the required certificates of birth, mariage and death, we will invoice you for the final 50% of our fee (€375 - 50% of €750). We will recharge the government fee of €278 to you in order to submit your online application form and pay the fee on your behalf. We will guide you every step of the way to ensure all your paperwork and certificates are in order prior to their submission to the Foreign Birth Register.
