Stamp 6 (Irish Citizenship)

Immigration stamps enable non-EEA nationals to live, work, invest, do business, and study in Ireland. The stamps vary by number and are subject to conditions. Stamp 6 is also known as Irish Citizenship by naturalisation; having lived in Ireland legally for a specific period, you may be eligible if you meet all the requirements.

Steps to becoming an Irish citizen through Naturalisation

All applications to obtain Irish citizenship by naturalisation are decided by the Immigration Service Delivery (ISD). These decisions are made on behalf of the Minister of Justice who has absolute control as to whether to grant naturalisation or not.

Applicants should take the following steps for a successful application for naturalisation

  • Meet the Conditions

  • Fill out an Application form

  • Gather Supporting Documentation

  • Make a Declaration

  • Send the application and pay the fee


The areas where applicants should meet conditions are age, character, residence in the state, and future intentions.


Applicants must be at least 18 years old if applying by themselves. Adults may apply for children. Children who may be eligible are:

  • Those born in Ireland after 1 January 2005 but did not qualify for citizenship by birth.

  • Those of Irish descent or Irish associations.

  • Those whose parent is a citizen by naturalisation.


Applicants must be of good character and will be asked on the form to declare actions and circumstances that may not reflect a good character. They will also be allowed to explain what led to the court or police actions.

The Minister receives information from Ireland’s National Police about applicant’s:

  • Criminal records.

  • Ongoing investigations.

  • Pending criminal cases.

  • Cautions or related warnings.

  • Certain civil cases such as barring.

  • Driving offences

Residence in the State

Reckonable residence means the period of stay in Ireland that counts toward becoming eligible

To be eligible, applicants must have had:

  • A continuous reckonable residence in the state of one year (365 days) immediately before the date they apply for naturalisation.

  • A total reckonable residence in the state of four years (1460 days) in the last eight years before the final one-year continuous residence.

Applicants can leave Ireland for up to 6 weeks (in total) per year and still be considered resident in that year. However, they may have to wait until the following year to apply if they spend over 6 weeks outside of Ireland in the year immediately before their application.

Young adults aged between 18 and 23 years and who entered Ireland legally with their family may use their parent’s reckonable residence if they do not have the required reckonable residence themselves.

They must be dependent on their parents and be in school or have gone straight to third-level college from school in Ireland.

Nationals of the EEA (the EU and Norway, Iceland and Lichtenstein), the UK, and Switzerland do not need to calculate reckonable residence when applying. They only need to show evidence of their residential history in Ireland.

In addition, they do not need to register for an Irish permanent residence permit as all periods of their residence in the state are counted towards naturalisation.

The spouse or civil partner of an Irish citizen is eligible to apply for naturalisation following three years of marriage or civil partnership and three years of reckonable residence in the state.

Persons granted refugee status are eligible to apply for Irish citizenship by naturalisation once they have three years of residence in the state calculated from the date of arrival.

Future Intentions

Successful applicants must continue to reside in the state after naturalisation and keep their Irish citizenship while they are residing abroad for a temporary period. Also, they must make a declaration of fidelity to the nation and loyalty to the State.

Finally, they must swear at a citizenship ceremony that they will observe the laws of Ireland and respect its democratic values.

The Minister for Justice can waive one or more of the conditions for naturalisation in the following circumstances if applicants:

  • Are of Irish descent or Irish associations.

  • Are a parent or guardian applying on behalf of a minor child of Irish descent or Irish associations.

  • Are naturalised parents applying on behalf of a minor child.

  • Are the spouse or civil partners of an Irish citizen or a naturalised person.

  • Have been resident abroad in the public service.

  • Are recognised as a refugee (under the 1951 Geneva Convention relating to the Status of Refugees) or a stateless person (under the 1954 UN Convention regarding Stateless Persons).


Applicants should use the checklist attached to the form to ensure that they have added all required documents and filled the form correctly. They must also pay a non-refundable fee of €175 using a banker’s draft only.

The draft must be made out to the Secretary-General, Department of Justice. No other type of payment is accepted. The application must be sent to the address specified on the form.

Processing time for Irish citizenship by Naturalisation

The Irish immigration system processes most applications within 12 months during which applicants may be asked to send more documentation for clarifications. Applicants will get an acknowledgement letter as well as an application number. They must, however, inform Immigration Service Delivery.
