Request Method
Applied through irishimmigration.ie — a different department and process from FBR entirely
Cost
Naturalisation application fee (set by ISD) plus a certification fee if granted — confirm current amounts before applying
Timeline
12–19+ months, longer if the discretionary review needs more evidence

Step by step

  1. 01

    Identify the issuing authority: Immigration Service Delivery (ISD), Department of Justice.

  2. 02

    Request method: Applied through irishimmigration.ie — a different department and process from FBR entirely.

  3. 03

    Budget for the cost (Naturalisation application fee (set by ISD) plus a certification fee if granted — confirm current amounts before applying) and the wait (12–19+ months, longer if the discretionary review needs more evidence) — order this before faster documents.

  4. 04

    Once received, follow Ireland's apostille and translation rules before submitting.

Notes & Tips

Fallback for cases that don't qualify for FBR. Requires a case built around four published categories (experiential, family, cultural connection, and establishment in Ireland), scoring 50%+ in at least two. Genuinely discretionary — not a guaranteed alternative to FBR.
