Guide · Foreign Births Register
The Foreign Births Register, in practical terms.
How the FBR works in practice — eligibility, evidence, sequencing and the pitfalls that most often slow applications down. Nothing on this page is legal advice.
Educational overview only. Rules and processing times change — always take written advice from qualified Irish legal counsel before acting.
How it works
Five stages, in the order they actually happen.
- 01
Confirm the chain
Establish which Irish-born ancestor citizenship flows through, and confirm no gap in the chain. If an intermediate parent is being relied on, verify the date of their FBR entry relative to your date of birth.
- 02
Assemble civil documents
Long-form birth, marriage and death certificates from every relevant jurisdiction. Order early — this is where most applications stall, not at the government stage.
- 03
Authenticate and translate
Certificates from certain countries require apostille certification. Non-English documents require certified translation. Your solicitor will confirm what applies.
- 04
Prepare and submit the application
Complete the FBR application, obtain witnessed signatures where required and submit with the full evidence pack. Independent Irish counsel manages the submission and follow-up.
- 05
Await entry and confirmation
Processing times vary and are set by the Department of Foreign Affairs. Once your registration is entered, you receive an official notice and can apply for an Irish passport.
Coordinating an FBR track with a move
Keep citizenship on the plan without letting it hold up the visa or the move.
Common pitfalls
Where FBR applications most often go slow.
Assuming a great-grandparent is enough on its own
Citizenship does not automatically pass through a great-grandparent. It passes only where the intermediate parent registered on the FBR before the applicant's date of birth.
Confusing short-form and long-form certificates
Short-form birth certificates rarely contain the parental information required. Order long-form (full) certificates from the start to avoid re-ordering later.
Registering after a child is born
If you register on the FBR after your child is born, that FBR entry does not pass citizenship down to that child. Timing matters — this is often the reason to move quickly.
Waiting for FBR before starting the visa or move
Most US arrivals move to Ireland on a visa or employment permit, with FBR running in parallel as a longer-term citizenship track. Do not sequence them the wrong way round.
Fees and timelines
What FBR costs and how long it takes.
| Applicant | Registration + certificate | Postage & handling | Total |
|---|---|---|---|
| 18 and over | €270 | €8 | €278 |
| Under 18 | €145 | €8 | €153 |
The Department of Foreign Affairs states that a completed application currently takes approximately 12 months to process, that applications are processed in strict date order, and that the form exists online only. Original certificates are returned by recorded post at the end of the process, and an Irish passport can only be applied for once registration is complete.

If you are still working out whether your chain qualifies at all, start with Irish citizenship by descent.

Common questions
Foreign Births Register: frequently asked.
- The Foreign Births Register is the Irish government mechanism that records the citizenship of people born abroad who claim Irish nationality through an Irish grandparent (or through a parent who was themselves registered on the FBR before their birth). It is administered by the Department of Foreign Affairs.
