    What is dual citizenship?

    The concept of dual citizenship means that you are a citizen of two countries at the same time. That means that you have the right to own two passports and that you can enjoy numerous benefits and privileges, such as unrestricted access to social services, in both of these countries. At the same time, if you are a dual citizen you are bound by the laws of the two states, which means you have dual obligations.

    Ireland allows dual citizenship but not all countries do. As laws regarding dual citizenship and the process of applying for it are complex, you should consult with an immigration lawyer before you submit your application.

    Does Ireland allow dual citizenship?

    Yes, UK nationals can hold both Irish and British citizenship as both countries allow dual citizenship. If you’re entitled to Irish citizenship (for example, through birth, descent, or naturalisation) and you also hold British citizenship, you don’t need to give up one to have the other. This is a common arrangement, especially for individuals born in Northern Ireland or with family ties across the two countries.

    It’s important to note that other countries do not allow dual citizenship or may have certain restrictions on dual citizenship. Because of this, it’s recommended to check with your home country’s citizenship laws to ensure that you can become an Irish citizen without having to renounce your first citizenship, or have to go through additional processes to allow this to happen.

    Who can acquire Irish dual citizenship through descent?

    If either of your parents were born in Ireland, you will automatically receive Irish citizenship. That applies even if you were born abroad and if your parents were not married at the time of your birth. That means that you do not have to go through the process of applying for dual citizenship in Ireland.

    If neither of your parents were born in Ireland, you can claim dual citizenship in Ireland through descent from your Irish grandparents. To be eligible for it, however, one of your grandparents has to have been born in Ireland.

    Only your Irish parents or grandparents can make you eligible for dual citizenship in Ireland through descent. Any other family members do not allow you to qualify. Keep in mind that either one parent or a grandparent who was born in Ireland must have had Irish citizenship at the time of your birth for you to be able to receive Irish citizenship through this route.

    Who can acquire Irish dual citizenship through naturalisation?

    Naturalisation in Ireland is a process allowing foreign nationals to become Irish citizens after living in Ireland for a certain qualifying period of time.

    To be able to apply for Irish citizenship by naturalisation you have to have lived in Ireland for at least five years of reckonable residence prior to submitting your application.

    The five years you spent in Ireland have to be during the nine years preceding your application. Moreover, right before your dual citizenship application you have to have spent one year of continuous residence in Ireland. During this one year you cannot spend more than six weeks outside of Ireland.

    Additional eligibility requirements include:

    • You are 18 years old or older – if you are married you can by under 18
    • You are of good character, which means you have not been convicted of any serious crimes and you have not previously breached the conditions of your immigration permission in Ireland
    • You intend to live in Ireland permanently
    • You agree to make a formal declaration of your loyalty to Ireland during your citizenship ceremony.

    Who can acquire Irish dual citizenship through marriage?

    If you are married to an Irish citizen, you can become naturalised, thus becoming a dual citizen in Ireland, after living in Ireland for three years.

    In addition to regular naturalisation requirements, to be eligible for Irish dual citizenship through marriage you have to:

    • Have been married or have been in a civil partnership with an Irish citizen for at least three years
    • Be living together in an ongoing marriage or civil partnership
    • Be at least 18 years old at the time of applying for Irish dual citizenship.

    Being married to an Irish citizen means you can apply for Irish dual citizenship after three years of reckonable residence instead of five. Still, the requirement of having to have spent one year of continuous residency immediately before your naturalisation application still applies.

    During the application process you will have to prove that you and your partner live together by submitting documents such as a shared rental agreement or evidence of having a joint bank account.

    How to apply for Irish dual citizenship?

    If you are applying for Irish citizenship through naturalisation, including the marriage route, you have to complete and submit the application form online. Then you have to gather documents that prove your eligibility for Irish citizenship and send them to the relevant application office. You also have to pay the application fee of €175.

    If you want to claim your Irish dual citizenship through descent, you do not have to go through the application process but you have to register your birth in the Foreign Births Register. You also have to provide a birth certificate of your parent or grandparent and evidence that they were Irish citizens at the time of your birth.

    The process of applying for dual citizenship in Ireland can be complex, especially as there are many documents you have to submit to prove that you meet the eligibility requirements. To make sure that there are no mistakes in your application and that no information or evidence is missing, hire one of our immigration consultants.

    What are the advantages of dual citizenship in Ireland?

    If your application for Irish dual citizenship is successful, you will receive full citizenship rights in Ireland. That means that you will be able to live there indefinitely, work without having to apply for an employment permit, vote in elections, serve on a jury, and apply for an Irish passport.

    In addition to that, as Ireland belongs to the EU, you will gain EU membership status. Some of the benefits that come with it include:

    • The right to travel between EU member states without having to apply for a visa
    • The right to move to an EU country without having to meet any residence criteria
    • The right to work in any EU country without having to obtain a work permission
    • The right to study in any EU country without having to get a student visa.

    If you have any questions about your Irish Dual Citizenship application, our team is happy to assist.

    I spoke with Saima Jabeen about the areas where I needed assistance. She was very helpful and provided me with clear and useful information. I was satisfied with the support and guidance she provided.
    Very positive professional experience. My immigration advisor Mariam Adebayo helped my wife successfully obtain her Spouse visa extension. At the very start we had a face to face meeting at their Oldham office to discuss our needs, explain the process and what evidence we would need. We later received a written confirmation of advice laying out everything from timeframes, fees and documentation needed. Through out we had video calls and regular emails for updates and when our input was needed, Mariam even uploaded all of the extensive evidence as part of the application process which I was very happy with as I know from my own experience this can take a while. I would definitely use IAS again, don't be fooled in to opting for cheaper options, I came to IAS after a poor experience with a different company and so came back as I'd had a good experience with IAS way back in the 90's so know that they have been around for a years. Thank you IAS Oldham and Mariam Adebayo.

    I would like to express my heartfelt gratitude to Abdul Mutee for everything he has done throughout my visa process. The past year was incredibly stressful, especially after facing two Canada visa refusals. During this difficult time, Abdul Mutee did not simply provide guidance; he actively worked on my case and supported me every step of the way when I felt overwhelmed and uncertain about my future. Thanks to his dedication, hard work, and continuous support, my UK visa has now been approved. This approval allows me to continue my education and pursue my dream of becoming a dentist. I truly believe that this achievement would not have been possible without his assistance and commitment. Abdul Mutee played a significant role in making this outcome possible, and I am deeply thankful for the relief, hope, and opportunity he has given me. His efforts have made a lasting impact on my life, and I will always be grateful for everything he has done. I will never forget the support, encouragement, and professionalism he showed throughout this journey. Abdul Mutee's help has made a real difference in my future, and I sincerely appreciate all of his hard work and dedication.

    I used IAS for my first visa and I must say it wasn't a pleasant experience. We didn't receive all the information, we would find out about things along the way and it made it all very stressful even though the application was successful. We were a bit reluctant to do it again for the renewal but went for it anyway due to lack of time. Anne Liu was out caseworker and she was terrific! Super on top of the case! She would review the docs very quickly after we submitted it and would immediately tell us what would be missing. She made herself available when we needed her all the way up to the appointment. Definitely made the experience more stress free!

    Anne has been nothing short of exceptional throughout mine and my husbands immigration query. From the very start, she was informative, diligent, understanding, compassionate and helpful. Any immigration matter is delicate and stressful for those involved and Anne met us with patience and kindness throughout, keeping us well informed and calm when everything felt tricky. We honestly couldn’t have asked for a better advisor and we are so grateful for everything that she did for us to get my husbands spousal visa approved. Her dedication and commitment proved enormously valuable and I will be welcoming my husband home tomorrow because of her. Without a doubt we will use her again in 2029 when required and we cannot recommend her enough for anyone going through a similar matter. Thank you Anne, from the bottom of our hearts, we will always appreciate you and remember your engagement fondly.

    Everybody at IAS has been professional and helpful. In particular my case worker, Elena Ampova simply could not have been more patient, friendly and approachable and knowledgeable. Nina and I found it difficult to supply information in the file formats required and Elena spent hours helping us. And the end result has been that my fiancée, Nina's visa application has been approved. Perfect service and a perfect result.

    I cannot recommend Mariam Adebayo at IAS highly enough. She supported me thoroughly from A–Z throughout my UK Global Talent Visa journey, ultimately helping me successfully obtain my visa through the Exceptional Talent route. From the very beginning, Mariam was incredibly professional, knowledgeable, patient, and attentive. She guided me through every stage of the process with clarity and reassurance, always making sure that my application was as strong and comprehensive as possible. What stood out most was how consistently she went above and beyond her dedication, responsiveness, and genuine commitment to achieving the best possible outcome for me were evident throughout the entire journey. Thanks to Mariam’s exceptional support and hard work, I now have the incredible opportunity to continue developing and practicing my talent in the UK. This is a truly significant milestone in my professional and creative journey, and I am extremely grateful for the role she played in making it possible. Mariam is an outstanding caseworker and a true asset to IAS. I wholeheartedly recommend her to anyone seeking immigration support, particularly those applying through the UK Global Talent route. Thank you, Mariam, for your dedication, guidance, and for helping turn this opportunity into a reality.

    My case worker Mariam Adebayo guided my fiancee, a Belarusian national and me on what documentation and translations were required and checked through everything at every stage. She then made the application on our behalf for a fiancee visa. The application was 100% successful with no other documentation required or any queries raised by UKVI. Mariam further assisted in getting our spouse visa after our marriage in May 2026. Again 100% successful. Mariam has been extremely thorough in every part of our fiancee and spouse visa. Everything went through without a hitch! I have no hesitation in recommending her. Peter and Teresa Welch.
