Stamp 6 Ireland 2026: Apply With Help From Irish Immigration Lawyers

Stamp 6 is an immigration endorsement for Irish citizens who also hold another citizenship. According to Immigration Service Delivery (ISD), dual citizens can apply for permission to remain in Ireland “Without Condition (Stamp 6)” if they hold or have the right to hold an Irish passport. There is no Stamp 6 application form and no fee.

Immigration Service Delivery (ISD) states that Stamp 6 applies where you hold dual citizenship — Irish citizenship and another — and have the right to hold an Irish passport.

If you hold a Stamp 6, you may enter and leave Ireland freely. You can enjoy all of the usual benefits of Irish citizenship.

You may apply for Stamp 6 if you are an Irish citizen with another citizenship and can provide the required evidence, and these include:

• Through your parents: If one of your parents was born in Ireland, you would be eligible and therefore must provide your mother or father’s long-form civil birth certificate, your mother’s civil marriage certificate if applying through your mother, your own long-form civil birth certificate and your current passport.
• Through your grandparents: If one of your grandparents was born in Ireland, you must provide your Foreign Births Registration certificate issued by the Department of Foreign Affairs and your current passport.
• By naturalisation or post-nuptial citizenship: If you have been naturalised as an Irish citizen through this method you must provide your current passport and original certificate of naturalisation, PNC certificate or current Irish passport.

If you hold a dual citizenship – Irish citizenship and one other, you may apply for the Stamp 6 in Ireland. In order to qualify you must hold or have the right to hold an Irish passport.

According to Immigration Service Delivery, there is no application form required for a Stamp 6 permission; applications are submitted by post with the required original documents.

Residence in the State

Reckonable residence refers to the duration of stay in Ireland that will count towards being eligible.

In order to be eligible, applicants will need to have had:

• A continuous reckonable residence in the state of one year before the date they are applying for naturalisation.
• For the standard naturalisation route, applicants generally need five years of reckonable residence, including one continuous year immediately before applying.

Applicants may leave Ireand for up to six weeks in total per year, and they will still be considered a resident in that year. They may then need to wait until the following year to apply if they have spent over six weeks outside of Ireland in the year right before their application.

Young adults between 18 and 23 who entered Ireland legally with family members, may use their parents’ reckonable residence if they do not meet the requirements themselves.

These young adults must be dependent on their parents and either be in school or have gone straight to third-level college after school in Ireland.

Different residence rules apply to some EEA, UK and Swiss nationals, so applicants should follow the current ISD naturalisation guidance for their circumstances. They will just need to show proof of residential history within Ireland.

Additionally, they will not need to register for an Irish permanent residence permit because all periods of their residence in Ireland will count towards naturalisation.

Spouses and civil partners of Irish citizens should check the separate naturalisation requirements before applying for Irish citizenship.

Refugee applicants should follow the current ISD naturalisation guidance because these rules concern citizenship rather than Stamp 6.

Future Intentions

Those who are successful in their applications will have to reside within Ireland after naturalisation and keep Irish citizenship while residing abroad for a temporary period. They will need to make a declaration of fidelity to the nation and loyalty to the State.

Successful applicants must attend a citizenship ceremony in which they will swear to observe the laws of Ireland and respect the democratic values.

The Minister for Justice is able to wave conditions for naturalisation if applicants:

• Are of Irish descent or associations.
• Are a parent or guardian who is making the application on behalf of a child of Irish descent or associations.
• Are naturalised parents who are making the application on behalf of a minor.
• Are the spouse or civil partners of an Irish citizen or naturalised individual.
• Have been a resident abroad within the public service.
• Are recognised as a refugee or stateless person.

The most efficient way to apply to become an Irish citizen by naturalisation is by downloading an application form online.

The different types of online form include the following:

• Form 8 – For persons who are at least 18 years of age.
• Form 9 – To be filled in on behalf of a minor child of a naturalised Irish citizen.
• Form 10 – To be filled in online by the parents of a minor child or Irish descent or associations.
• Form 11 – To be filled in online by the parent or guardian of a minor child born in Ireland who was not entitled to Irish citizenship when born.

It is important to go through each note attached to the forms, and write ‘N/A’ for questions that do not apply to you. You will be permitted to use professional immigration lawyers if you prefer.

Lastly, you will need to find Irish citizens who are able to give their honest opinions about your character as an applicant, they will act as your referee and submit details along with a signature.

You will need to provide specific documents on your application form which will identify you and determine the history of your residence.

You must also send a full-colour copy of your passport. This must have been certified by a solicitor, commissioner for oaths or a notary public.

The other documents which will need to be certified as true copies are:

• Your birth certificate.
• Your spouse’s birth certificate (in the instance that the application is based on marriage to a citizen of Ireland).
• Your marriage or civil partnership certificate (in the instance that the application is based on your marriage to a citizen of Ireland).

If you are an adult applicant you will have to apply for and include a tax clearance with your application form. This will be used to prove that there are no issues with your tax affairs. If you have never worked in Ireland you may include a note that explains an inability to provide a tax clearance certificate.

All applicants will have to provide a written statutory declaration in which they swear that all details on their application form and supporting documents are accurate.

This statement will have to be witnessed by an authorised person such as a notary public, commissioner for oaths, lawyer or a peace commissioner.

In the instance that it is a spouse or civil partner who is an Irish citizen, they must make a statutory declaration if the application in question is based on the applicant’s marriage or partnership with a citizen of Ireland.

Applicants must include two colour passport photos with their application form, and the chosen witness will put the date and their signature on the back.

All applicants should check to ensure that they have attached every supporting document and filled out their form accurately.

Upon completion of the application, a non-refundable fee of €175 must be paid. This can only be paid using a banker’s draft.

This draft will be made out to the Secretary-General, Department of Justice. No other form of payment will be accepted for this application. Your application needs to be sent to the address specified on the form.

Most applications will be processed by the Irish immigration system within 12 months. Within this time you might be required to send through more documents for further clarification.

All applicants will get a letter of acknowledgement and an application number. Applicants must be sure to inform Immigration Service Delivery.

If your application is successful, you will then be asked to pay the certification fee. The Immigration Service Delivery will then send your Irish Residence Permit (if you are a non-EEA/EU or non-Swiss citizen).

Once this application process is entirely complete and you have been successful, you can then become an Irish citizen and apply for an Irish passport.

If your application ends up being unsuccessful, you will be provided with reasons for this negative result. If you are unsuccessful you may apply again, or utilise Irish immigration lawyers in order to gain a successful outcome.

The fee for applying for Irish citizenship by naturalisation is €175. Upon approval of this application the following fees will then apply:

• Application on behalf of a minor – €200
• Widow, widower or surviving civil partner of an Irish citizen – €200
• Refugee, stateless person or programme refugee – €0
• Others – €950
