Everything You Need to Know to Become an Irish Citizen


Becoming an Irish citizen grants you full rights to live, work, and study in Ireland or any other EU country. There are several pathways to citizenship, including birth, descent, marriage, and naturalization, each with unique requirements. Here’s a detailed guide on how to become an Irish citizen, covering eligibility criteria, necessary documentation, and application processes for each pathway.


1. Pathways to Irish Citizenship

There are four main ways to become an Irish citizen:

  1. Citizenship by Birth: For those born in Ireland or to Irish parents.
  2. Citizenship by Descent: For individuals born outside Ireland to Irish parents or grandparents.
  3. Citizenship by Marriage: For non-Irish citizens married to or in a civil partnership with an Irish citizen.
  4. Citizenship by Naturalization: For non-Irish residents who meet the residency requirement.

Each pathway has specific requirements, so choosing the right one is essential.


2. Irish Citizenship by Birth

Irish citizenship is automatically granted to individuals born in Ireland under specific conditions:

Automatic Citizenship by Birth:

  • Born in Ireland Before January 1, 2005: Anyone born in Ireland before this date is automatically an Irish citizen, regardless of parents’ nationality.
  • Born in Ireland After January 1, 2005: Citizenship is granted if at least one parent is an Irish citizen, a British citizen, or has lived legally in Ireland for at least three of the previous four years.

If neither parent meets these criteria, the child does not automatically qualify for citizenship but may still have other options through descent.


3. Irish Citizenship by Descent

If you were born outside Ireland but have an Irish parent or grandparent, you may be eligible for Irish citizenship by descent.

Eligibility for Citizenship by Descent:

  • Parent Is an Irish Citizen: You’re automatically an Irish citizen if born outside Ireland to an Irish-born parent.
  • Grandparent Is an Irish Citizen: If you have an Irish-born grandparent, you can register in the Foreign Births Register to obtain citizenship.

Application Process for Citizenship by Descent:

  1. Register in the Foreign Births Register: This is required for those claiming citizenship through a grandparent.
  2. Submit Required Documents: Including birth certificates, passports, and evidence of your Irish grandparent’s birth.
  3. Pay Application Fee: The fee for registering is approximately €278.

Upon successful registration, you’ll be granted Irish citizenship, and you may apply for an Irish passport.


4. Irish Citizenship by Marriage or Civil Partnership

Non-Irish citizens married to or in a civil partnership with an Irish citizen may apply for citizenship if they meet certain residency conditions.

Eligibility for Citizenship by Marriage:

  • Residency Requirement: You must have lived in Ireland for at least 3 years out of the last 5 years and have been married to or in a civil partnership with an Irish citizen for at least 3 years.
  • Continuous Residence: Continuous residence in Ireland for the 12 months immediately before the application is mandatory.

Application Process for Citizenship by Marriage:

  1. Submit Application Form 8: Fill out Form 8 for citizenship by marriage.
  2. Provide Supporting Documents: Include proof of residence, marriage or civil partnership certificate, and the Irish spouse’s citizenship documentation.
  3. Pay Application Fee: There is a €175 application fee and a €950 certification fee once approved.

If granted, you’ll receive an Irish certificate of naturalization.


5. Irish Citizenship by Naturalization

For foreign nationals who have lived in Ireland long-term, naturalization is the most common route to citizenship.

Eligibility for Citizenship by Naturalization:

  • Residence Requirement: You must have lived in Ireland legally for at least 5 years out of the past 9 years, including 1 year of continuous residence immediately before applying.
  • Good Character Requirement: Must have no serious criminal convictions.
  • Financial Independence: You must show financial stability and the ability to support yourself in Ireland.

Application Process for Naturalization:

  2. Submit Required Documents: Include proof of residence, passport, financial records, and any previous visas or permits.
  3. Pay Application Fees: The initial application fee is €175. Upon approval, there’s an additional €950 certification fee.

Naturalization applicants receive a certificate of naturalization, officially granting Irish citizenship.

Irish citizenship comes with numerous benefits, making it a valuable asset for those eligible:

  • Live and Work in the EU: As an Irish citizen, you gain full rights to live, work, and study in any EU or EEA country.
