Key Takeaways
• Irish citizenship by descent requires vital records and proof of ancestry through parent or grandparent links.
• Foreign Births Register applications currently take 9–24 months and cost €278–€350, plus document fees.
• Registration before a child’s birth is crucial for passing citizenship to future generations born abroad.
For many people with Irish ancestry, getting Irish citizenship feels like reclaiming a valuable link to family history, culture, and opportunities in Ireland 🇮🇪 and across Europe. The process for obtaining Irish citizenship based on ancestry follows clear rules, but the right path and steps depend on how directly you are related to your Irish ancestor. This guide will break down those rules in simple language, walking you through eligibility requirements, how to use the Foreign Births Register, what documents to gather, expected processing times, fees, and what you gain as a citizen.
Pathways to Irish Citizenship by Ancestry
If you or your parents or even your grandparents were born in Ireland 🇮🇪, the Irish government provides well-defined roads toward becoming an Irish citizen. The closer your family connection, the simpler the process tends to be.
Automatic Citizenship by Parentage
The fastest and least complicated path to Irish citizenship is if your mother or father was born in Ireland 🇮🇪. In this case, you are already an Irish citizen by law—even if you were born somewhere else. You don’t need to go through any special citizenship application. Instead, you can jump straight to applying for an Irish passport. All you need is to show:
- Your parent’s Irish birth certificate
- Your birth certificate, linking you to that parent
- Your photo ID
As reported by VisaVerge.com, this remains one of the most straightforward ways to claim your Irish passport if you qualify by parentage.
Citizenship by Descent (Using the Foreign Births Register)
Not everyone has a parent born in Ireland 🇮🇪, but many have grandparents who were. If your grandparent was born on the island of Ireland, and your parent was not, Irish law allows you to become a citizen by descent. This process is managed using something called the Foreign Births Register (FBR).
Who can use the Foreign Births Register?
- If you have a grandparent born in Ireland 🇮🇪 and your parent was born elsewhere, you can register yourself on the FBR. Once your registration is approved, you become an Irish citizen from the date of registration.
- If your parent was not born in Ireland 🇮🇪, but became an Irish citizen before you were born (either through their own FBR registration or by naturalizing), you too may register for citizenship on the FBR.
Once you are on the Foreign Births Register, you have the same citizenship rights as someone born in Ireland, including the right to live, work, and vote there. You may also apply for an Irish passport right after your FBR registration is approved.
More Distant Ancestry: Great-Grandparents
Irish citizenship law is generous, but it sets clear limits.
- If your connection to Ireland 🇮🇪 comes only from a great-grandparent or even earlier generations, citizenship is not automatic.
- The law does allow for something called “chain registration,” where every generation registers before the birth of the next. This means, for example, your parent would need to become a citizen through the FBR before your birth, and then you could register in turn.
- These rare cases demand strong records for every generation. Missing a step breaks the chain. Without a registered link in every generation, you would need to consider naturalization or very limited special applications, which have no guarantee of success and tend to take much longer.
For those applying solely on the basis of a distant ancestor or Irish associations (for example, for a connection beyond a parent or grandparent), the procedure is much tougher. You must show not just ancestry, but also a strong personal connection or service to Ireland 🇮🇪. Processing in these special cases often takes over 30 months and the decision is left to the Minister for Justice.
Eligibility Requirements for Citizenship by Ancestry
Whether through birth, the Foreign Births Register, or special association, you must be able to clearly prove your connection to your Irish ancestor. The government takes this proof very seriously.
Key requirements include:
- Full civil birth certificates for you, your parent(s), and ancestor(s), showing the family link
- Marriage certificates where relevant
- Certified identification documents (such as passports or national ID cards)
- Proof of address for each applicant and ancestor where required
- Passport-size photographs, signed/witnessed as instructed
It is vital to note that if a parent wants to pass on citizenship by descent, they must secure their own registration on the Foreign Births Register before the birth of their child. Failing to do so means that the child will not inherit Irish citizenship automatically, and may need to look at other, sometimes less direct, paths like naturalization.
Residency and Living Requirements
Unlike many other countries, claiming Irish citizenship through ancestry does not need you to have lived, worked, or studied in Ireland 🇮🇪. You can live anywhere in the world and still apply, as long as you provide a strong paper trail connecting you to your parent or grandparent born in Ireland 🇮🇪.
However, for those seeking citizenship by naturalization (not ancestry), physical residency in Ireland 🇮🇪 is required, and you must meet strict rules about how long you have lived there.
Foreign Births Register: Step-by-Step Application Process
Most applicants with Irish ancestry will deal with the Foreign Births Register. Here’s how it works, in plain terms:
- Gather Documents
- You will need civil birth certificates for each generation, including yours, your parent’s, and your grandparent’s if applying through that line.
- Bring together marriage certificates if names have changed.
- Prepare certified photo identification (passport or national ID) for both you and your Irish ancestor(s).
- Collect proof of address (such as a utility bill or bank statement).
- Get recent passport-sized photographs—signed and witnessed as required.
- Apply Online
- Go to the Department of Foreign Affairs’ official website. Complete the online form for Foreign Births Registration.
- After filling out your details, print the forms.
- Submit Documents
- Post the printed application forms, all supporting documents, and payment to the address provided in the online process.
- Processing Wait
- As of now, applications can take between 9 and 24 months to process because of high demand. Some complex cases might take even longer.
- Certificate of Registration
- Once your application is approved you will receive your certificate showing that you are an Irish citizen from that date. With this, you may move on to apply for an Irish passport.

Citizen Rights and Responsibilities
Once granted Irish citizenship, you enjoy all the rights of any Irish person, including:
- Voting in elections in Ireland 🇮🇪
- Running for public office
- Living, working, or studying anywhere in Ireland 🇮🇪 and, as a European Union (EU) citizen, moving freely across EU countries
- Accessing healthcare, education, and other state services
At the same time, you take on responsibilities, like obeying the laws of Ireland 🇮🇪, serving on a jury if called, and (in rare cases) being available for certain forms of national service.
Dual and Multiple Citizenship
Ireland 🇮🇪 allows dual citizenship. This means you can hold Irish citizenship along with another country’s citizenship (such as American or Canadian), unless the other country’s laws forbid it. You don’t lose your original citizenship by gaining Irish citizenship through ancestry or by being on the Foreign Births Register.
Citizenship for Children and Dependents
With every new generation, the rules about passing on Irish citizenship change a bit:
- If you are an Irish citizen by ancestry but not born in Ireland 🇮🇪, your children can only become citizens by also registering with the Foreign Births Register, and only if you registered before their birth.
- If you get FBR registration after your child is born, your child is not automatically eligible. This means timely registration matters if you want your children to benefit.
Fees and Processing Times
Processing times have grown longer as demand rises. The fee varies by location (for instance, higher for those applying from outside Europe), but expect to pay around €278–€350 for FBR registration, plus added costs for gathering and mailing documents and getting certificates notarized.
If you’re considering making your claim by Irish ancestry, be aware that missing or unclear documents are a major reason FBR applications get delayed or rejected. Slowdowns are also common if forms are incomplete or if the generational links are not well established.
Common Pitfalls and Denial Reasons
- Not providing certified or official documents for every person in the generational link (for example, birth certificates, name change documents, marriage certificates)
- Failing to register with the Foreign Births Register before the birth of children, breaking the chain of descent
- Losing key documents showing the direct link to an Irish-born ancestor
- Trying to claim based solely on great-grandparent or more distant relationships without a clear, unbroken chain of citizenship
- Relying on “special associations” with Ireland 🇮🇪 rather than direct descent, which have high denial rates
If denied, you may appeal or try naturalization, but you should only expect a positive result if you can provide missing documents or correct errors.
Case Studies to Make It Clear
- Jane, born in New York, has a mother born in Dublin: Jane simply applies for an Irish passport with birth certificates proving her Irish parentage. She is instantly recognized as a citizen under Irish law.
- Michael’s grandmother was born in Cork. His parents and he were born in Canada: Michael gathers his and his parents’ birth certificates, shows his direct link, and applies to the Foreign Births Register. After approval, he applies for a passport.
- Sophie’s great-grandfather was born in Galway, but neither her grandparent nor parent ever applied for Irish citizenship: Sophie cannot claim citizenship unless her parent registered with the FBR before her birth. If not, her path would require more complex special consideration by the Minister, which is rarely successful.
Preparation and Where to Find Help
To make your Irish citizenship dream a reality, start early. Contact relatives to help track down records, order any government certificates that are missing, and check the full required document list so nothing holds up your FBR application. Double check for certified translations if documents aren’t in English.
Official resources are available if you need in-depth guidance. The Citizens Information website has step-by-step instructions, and the Department of Foreign Affairs also provides downloadable forms and details about requirements and fees.
Both sites are trustworthy, updated, and directly linked to government policy. Don’t be tempted by third-party sites promising to “fast track” your claim for a fee.
Conclusion and Next Steps
If you have Irish ancestry, the pathway to Irish citizenship is open if you meet the clear requirements and commit to the careful work of gathering documents. Automatic routes by parentage are straightforward, while most with Irish-born grandparents will use the Foreign Births Register. Keep in mind the importance of the correct paperwork, prompt registration for you and your children, and the long timelines for processing.
Irish citizenship brings not only a passport but a host of rights and the chance to connect with your heritage. If you want to get started, explore the Department of Foreign Affairs site for the latest forms and information. Preparation, patience, and attention to detail will help you reach your goal of becoming a citizen of Ireland 🇮🇪 through your family roots.
