Guide only — this matter needs a solicitor. Under Irish law this work must be carried out by a solicitor, so it is not sold on this site. The information below explains what is involved so you can brief a solicitor with confidence.

Frequently asked questions
How much does a citizenship residency calculation cost in Ireland?
This page is a free guide — nothing on it is for sale. Solicitors set their own fees for this work and must give you a written costs estimate (a section 150 letter) before starting. Get quotes through the Law Society of Ireland’s Find a Solicitor directory.
What is reckonable residence?
Reckonable residence is the time spent living in Ireland that counts towards citizenship. Not every immigration permission counts, and absences from the State can also affect the calculation.
Why do I need a precise residency calculation?
If you apply before you have enough reckonable residence, your application is likely to be refused and you may lose the application fee. A precise calculation helps you apply at the right time.
