What is Irish Citizenship by Marriage?
A foreign national partner of an Irish citizen does not automatically get the right to Irish citizenship themselves. To be eligible for Irish citizenship by marriage, you must meet all relevant conditions as specified in the Irish Nationality and Citizenship Acts 1956-2004.
Irish citizenship through marriage or civil partnership is actually a sub-category of citizenship through naturalisation in Ireland. The only considerable difference between the two processes is the number of years you are required to live in Ireland.
Usually, foreign nationals must live in Ireland for at least five years before they can apply for citizenship. The residency requirement, however, is only three years if they have an Irish citizen spouse or civil partner.
Note that while Immigration Service Delivery (ISD) reviews the applications for Irish citizenship by marriage/civil partnership on behalf of the Minister for Justice, the Minister has the final authority to grant citizenship.

Eligibility Requirements for Americans
If you are a US citizen partner of an Irish national and want to apply for Irish citizenship through marriage or civil partnership, you must meet the following eligibility criteria:
- You must be 18 years old or over at the time of application
- You must have been married or in a civil partnership with an Irish citizen for three years or more
- You must be living with your spouse or partner who is of Irish nationality in Ireland legally
- You must have resided in Ireland for at least three years out of 5 years prior to your application
- You must have continuous residence in Ireland for one year before the date of your application
- You must intend to continue to reside in Ireland after you become a citizen
- You must agree to make a declaration of fidelity to the nation of Ireland
- You must be determined to be of good character. This includes a lack of prior criminal record, pending criminal cases, or involvement with the Irish police force
Spouses/civil partners of Irish citizens can count any legal residence period in Northern Ireland as well while calculating the reckonable residence for their citizenship application.
Required Documents for Irish Citizenship Through Marriage
You will usually need the following supporting documents:
- Proof of identity, e.g., your passport or Irish Residence Permit card
- Proof of residence in Ireland (e.g., bank statements, copy of P60, rent agreements, utility bills, etc.)
- Marriage or civil partnership certificate, or the relevant affidavit form
- Your birth certificate or relevant affidavit form
- Your Irish citizen spouse or civil partner’s birth certificate
- Your current and old passports
- A printout of the online residency calculator page from the Department of Justice’s website unless you are exempt
- Details and signatures of three references. They must be Irish citizens who know you well enough to form an opinion about your character, and willing to act as a referee for you
- Two coloured passport photos signed with date on the back by the witness who have signed your statutory declaration
An immigration officer may contact you during the application process to request additional documentation. In this case, you must respond to the immigration office by the deadline given so that your application is not delayed or rejected.
The Garda National Immigration Bureau has absolute discretion over final application decisions.
Documents that are not originally in English or Irish may be required to have certified translated copies made. Original documents will be returned to you by post. Copies will be kept by the immigration office.
How to Apply for Irish Citizenship Through Marriage
Here’s a step-by-step guide to apply for Irish citizenship by marriage:
- Start your application by filling up the Form 8 online. To register, you need a valid email ID (contact ISD for paper forms if you cannot access the online service)
- Upload the required supporting documents online. All uploads must be true copies certified by an appropriate witness (e.g., a practising solicitor, Commissioner for Oaths, Peace Commissioner, or Notary Public)
- As an Irish citizenship applicant through marriage/civil partnership, your application must include the relevant Statutory Declaration, duly signed by you in the presence of a practising solicitor, Commissioner for Oaths, Peace Commissioner, or Notary Public
- Tick the Statutory Declaration box to legally declare that you understand the application form, and that all the facts provided in the form by you are true and correct to the best of your knowledge
- Pay the required application fee online and submit your form to complete your online application process
- If you are using a paper form, send the completed form and other supporting documents to the Department of Justice, along with a bank draft (drawn on an Irish bank and payable to the Secretary General, Department of Justice) towards fee payment
After processing your application, ISD will submit a review report to the Minister of Justice. The Minister has the final authority to approve or reject your application.
Processing Times
Most citizenship by marriage applications are processed within 12 months. However, this timeline may increase if you have submitted an incomplete form, or supporting documents are missing.
The processing time is measured from the date the ISD receives your application, documents, and application fee to when the decision is delivered to you.
In the event that you are missing documents or additional documents are requested, you may be given up to 28 days to provide them. If you fail to provide them by the deadline, your application may be delayed or refused.
Confirm that your application is complete and correct prior to submission. This is the best way to ensure that your application for citizenship is processed in the quickest window of time.
Costs and Fees
At the time of application, you will be required to pay a fee of €175.
If your application is approved, the certificate of naturalization will cost €950.
You may have additional costs and fees when applying for Irish citizenship through marriage depending on your individual circumstances.
What If My Application Has Been Approved?
ISD will send you an approval letter if your application is approved. It will have certain documents mentioned which must be sent to ISD at this stage. Plus, you will have to pay a certification fee (if applicable).
You will have to attend a citizenship ceremony next per invitation, and make a declaration of fidelity and loyalty to Ireland. Following the ceremony, your Certificate of Naturalisation will be sent to your residential address by registered post.
Reasons For Denial
Applications for citizenship in Ireland may be denied for a variety of reasons, including:
- Being unable to provide adequate evidence of the relationship between the Irish resident spouse or partner and the applicant.
- Being unable to prove the ability to provide financial support by the spouse or partner.
- Certain situations in which it is determined that the spouse/ partner or foreign national applicant is a criminal or health risk to the state of Ireland.
In the event that your citizenship application is denied, you will receive a letter with the reason for the decision. If your Irish citizenship application was recently denied, contact Total Law for help to appeal or re-apply.
What If My Application Has Been Refused?
In case of incorrect or incomplete forms, ISD will straightaway return your application to you, to start the whole process afresh. If any supporting documents are missing, you will have up to 28 days to provide them. Your application may be refused if you fail to submit on time.
If the Minister decides not to approve your application, ISD will inform you of the refusal reason(s). You may apply again at any time, but ensure you pay particular attention to the previous refusal reason(s) and take necessary steps before you re-apply.
American Irish Dual Nationality
Since both the US and Ireland allow dual nationality, you won’t have to renounce your US citizenship to become an Irish citizenship through marriage. As an American Irish dual citizen, you will be entitled to rights and benefits entitles to their respective citizens in both countries.
However, note that dual citizenship also means that you will be subject to laws of both countries, including tax regulations. Consult an international tax consultant to avoid double taxation or tax penalties.
How Can Total Law Help?
Becoming a naturalised Irish citizen through marriage or civil partnership is a complex process. If the clause of reckonable residency applies to your case, you will also have to carefully consider whether you are meeting that criterion or not. Even if you meet all requirements, you must fill up the relevant forms correctly and submit all required documents for a positive outcome.
A refusal will result in going through the entire process once again and may even jeopardise your life in Ireland as a family.
This is where our specialist Irish immigration lawyers can help. They can increase your chances of receiving a positive decision by providing legal advice and administrative support to ensure that your application adheres to ISD regulations.
We can also help if you’re looking to obtain Irish citizenship through other means, such as through Irish associations or through descent. For further information, contact us today on +1 844 312 4979 or use our online contact form to get in touch with our team of qualified immigration lawyers.

Frequently Asked Questions
You are not required to obtain a lawyer in order to apply for Irish citizenship through marriage, but many applicants choose to use one to navigate the process. Applying for Irish citizenship can be a challenging process. The citizenship application process is more complicated than applying for a visa. Residency requirements can be complex. A qualified immigration professional can assess that you meet the required criteria, gather documents, make a declaration, and more. It can be helpful to have professionals with expertise in Irish law by your side to help with each aspect of the citizenship application process.
Citizenship ceremonies are required for all foreign nationals who will become Irish citizen. Typically at the citizenship ceremony, you will receive your certificate of naturalization. In the event that you are exempt from the citizenship ceremony, you will receive your final documentation by post.
When you apply for Irish citizenship, you will not receive an Irish passport automatically. You must first be granted citizenship and attend a citizenship ceremony to receive your certificate of naturalization. Once your immigration status is updated, you can apply for an Irish passport. It may take a few weeks to receive your original documents back from your citizenship application in order to apply for a passport.
No. Marriage or civil partnership with an Irish national does not give you the automatic right to citizenship in Ireland. You must meet eligibility requirements for naturalization, apply, and be approved by the immigration office.
