Becoming an Irish citizen is a big step, and for many of our clients it is the end of a long road. On paper the application looks simple, but small mistakes in the residence count or the documents are the most common reason applications are returned.
Who can apply for Irish citizenship
You can usually apply for citizenship by naturalisation if you are over 18, of good character and intend to keep living in Ireland. You also need 5 years of reckonable residence in the last 9 years, including 1 full year immediately before you apply. The rules are set out in the Irish Nationality and Citizenship Act 1956.
If you are married to, or in a civil partnership with, an Irish citizen, you need 3 years of residence in the last 5, and you must have been married or in a civil partnership for at least 3 years.
EU citizens can apply too. You do not need an immigration stamp, but you still need to prove where you lived and when, and that is where many EU applications go wrong.
Which time counts towards citizenship
Not every day you spent in Ireland counts. Time on Stamp 1, 3, 4 and 5, and time living here as an EU citizen, usually counts. Time on Stamp 2 or 2A student permission does not, and neither does time waiting for an international protection decision or time without a valid permission.
You can be out of Ireland for up to 6 weeks in the year before you apply, plus a further 6 weeks in exceptional cases. Small gaps between permissions, an expired card or a long trip home can all reduce your total. That is why we work out your residence from your stamps and travel history before you pay any application fee.
Documents you will need
The exact list depends on your situation, but most applications need:
- Your current passport and any expired passports covering your residence
- Proof of your immigration permissions, such as IRP cards or letters
- Proof of address for each year, such as a lease, utility bills or bank statements
- Proof of income or employment
Missing or uncertified documents are the most common reason applications are sent back, so we go through everything with you before it is submitted.
How the application works
- We check your reckonable residence and your documents
- You pay the €175 application fee and the application is submitted online
- ISD reviews it and may ask for more information
- If you are approved, you pay the certificate fee and attend a citizenship ceremony
- You receive your certificate of naturalisation and can apply for an Irish passport
Processing times change and can run for many months. You can follow the current guidance on the Irish Immigration Service website. Please plan for a long wait: applications often take well over a year, and many take longer.
If your application has been delayed for a long time without a clear reason, there may be options, including judicial review. In our experience, writing to ISD about a delay is usually only worthwhile once an application has been waiting for about 2 years. If yours has been waiting that long, we can review it and tell you whether a letter or further steps make sense.
Proposed changes in 2026
In September 2026 the Government approved the drafting of the Irish Nationality and Citizenship (Amendment) Bill 2026. It proposes raising the residence period from 5 to 8 years, and from 3 to 5 years for spouses and civil partners. It also proposes tests in English, Irish or Irish Sign Language and in Irish civics, a minimum income requirement and restrictions for people who received certain welfare or housing supports.
Under the published outline, the new residence rules would not apply to applications already lodged when the law starts. The law has not been passed yet and the details may change. If you already meet today's requirements, talk to us about applying now.
How we can help
We check whether you qualify before you pay anything to the State, prepare your documents in the order ISD expects and deal with any questions ISD raises along the way. If you were refused before, we look at exactly why and help you prepare your next application. If your application has been delayed for about 2 years or more, we advise you on what can be done.

Frequently asked questions
Does my time as a student count?
No. Time on Stamp 2 or 2A student permission is not reckonable residence. Time on most other permissions, such as Stamp 1 and Stamp 4, usually counts. We check your history before you apply.
What happens if my citizenship application is refused?
There is no appeal against a naturalisation refusal. You can make a new application, and in some cases a refusal can be challenged by judicial review. We review the reasons and tell you which route makes sense.
My application is taking a long time. Can you help?
Waiting is normal. Applications often take well over a year, and many take longer. In our experience, writing to ISD about a delay is usually only worthwhile once an application has been waiting for about 2 years without a clear reason. Before that, we can check whether anything is missing from your file.
How much does it cost?
The State charges an application fee of €175 and a certificate fee if you are approved. Our own fee is fixed and agreed in writing before any work starts.
