Irish Citizenship through Ancestry & Foreign Birth Registration
Obtain Irish Citizenship through Your Irish Ancestry
Immigration Solicitors Dublin and Cork handle all types of Naturalisation and Citizenship applications. In recent years, we have received thousands of queries from individuals seeking Irish citizenship through descent and ancestry. Immigration Solicitors Dublin and Cork provide full guidance and assistance to applicants who wish to register their birth through the Foreign Births Register to acquire Irish citizenship by descent.
Do You Have an Irish Parent or Grandparent?
Hundreds of thousands of people have Irish grandparents and ancestry. If you are one of them, you should seize this golden opportunity to claim your Irish citizenship by descent by registering on the Foreign Births Register.
As there is often confusion regarding the process of acquiring Irish citizenship by descent, we have outlined the various application pathways below:
Were You Born Outside of Ireland to Irish Parents or Do You Have Irish Grandparents?
✔️ If you were born outside of Ireland to an Irish parent who was born on the island of Ireland, you are automatically an Irish citizen. You do not need to take any further steps and can apply for an Irish passport immediately.
✔️ If you were born outside of Ireland to a parent who was also born outside of Ireland, you are entitled to Irish citizenship, but you must register on the Foreign Births Register to obtain it.
✔️ If you were born outside of Ireland but have a grandparent who was an Irish citizen born on the island of Ireland, you are entitled to Irish citizenship but must register on the Foreign Births Register.
✔️ If both your grandparent(s) and parent(s) were born outside of Ireland, you may be eligible to become an Irish citizen if you register with the Foreign Births Register. However, the parent from whom you derive Irish citizenship must have registered on the Foreign Births Register before your birth.
✔️ If your parent was an Irish citizen but was deceased at the time of your birth, you are still entitled to Irish citizenship.
✔️ You can derive citizenship through an Irish parent regardless of whether your parents were married at the time of your birth.
✔️ If you were born abroad and adopted by Irish parents, you may be eligible to apply for the Foreign Births Register.
✔️ If you were born abroad and your parent is a naturalised Irish citizen, you are eligible to register on the Foreign Births Register.
Do You Have Irish Citizen Parents?
✔️ If you were born in Ireland after 1st January 2005 and have parent(s) who are Irish citizens, you are automatically an Irish citizen.
Foreign Births Register
The Department of Foreign Affairs maintains the Foreign Births Register, where eligible individuals can apply for Irish citizenship. If you qualify to register, your Irish citizenship is effective from the date of registration, not from the date of your birth.
How to Apply
Immigration Solicitors Dublin and Cork can advise on all aspects of claiming citizenship through Foreign Birth Registration. The application form (available online) must be completed, and supporting documentation submitted to the Department of Foreign Affairs for processing.
Once the process is complete, you will receive a Foreign Birth Registration Certificate confirming your entry on the Irish Register of Foreign Births. From that date, you are an Irish citizen and can apply for an Irish passport.
You cannot apply for an Irish passport until you are registered on the Foreign Births Register.
Children of Foreign National Parents Born in Ireland
✔️ A child born on the island of Ireland to an Irish or British citizen is automatically an Irish citizen.
✔️ A child born on the island of Ireland is entitled to Irish citizenship if their parent has the right to reside in Ireland or Northern Ireland without restriction, or if their parent was legally resident in Ireland for three of the four years immediately before their birth.
Applying for a Passport for an Irish-Born Child of Foreign National Parents
✔️ Residence in Ireland: Non-EEA nationals must provide proof of residence, including a letter listing their passport’s immigration stamps and their Certificate of Registration.
✔️ EU Citizens: Must provide proof of residence in Ireland for three years before the child’s birth. Acceptable documents include tax records, bank statements, utility bills, rental agreements, and school letters.
✔️ Residence in Northern Ireland: Non-EEA nationals with UK residency must apply to the Department of Justice and Equality for a Certificate of Nationality for their Irish-born child. This application must include a completed Declaration Form C, proof of residency, and supporting documents. Once the certificate is received, parents can apply for an Irish passport for the child.
Advantages of Becoming an Irish Citizen
✔️ You become an EU citizen.
✔️ You can live, work, and travel freely across the 27 EU Member States, 3 EEA states, and Switzerland.
✔️ Your children can become Irish and EU citizens, ensuring future benefits like unrestricted education access.
✔️ You can secure lower university fees across Europe compared to non-EU citizens.
✔️ You avoid non-EU passport queues at European airports.
Irish Citizenship Through Other Irish Ancestors
Unless at least one parent or an Irish-born grandparent was an Irish citizen at the time of your birth, you cannot claim Irish citizenship based on extended ancestry (e.g., great-grandparents). Additionally, having an Irish relative such as a cousin, aunt, or uncle does not entitle you to Irish citizenship if neither your parents nor grandparents were Irish citizens at your birth.
Recent Trends in Citizenship by Descent Applications
Over the years, we have handled many Foreign Birth Registration cases with complex circumstances. Some common challenges include:
✔️ Name changes without legal documentation – Many individuals who emigrated to the UK or the USA informally changed their names.
✔️ Adoption cases – Some birth certificates may not include a parent’s name, making it harder to prove eligibility.
✔️ Estranged parent relationships – Clients who cannot obtain their parent’s passport or ID may face documentation issues.
These are just a few examples of the complex cases in which we have successfully helped clients register on the Foreign Births Register. If you need assistance, Immigration Solicitors are here to guide you through the process.
