About this service
Recognition of Dual Citizenship (Stamp 6)
Irish citizens who also hold another citizenship, and live in Ireland using their non-Irish passport, can have their status recorded with a Stamp 6 endorsement. It shows immigration officers that you're Irish and can live in Ireland without conditions. There's no application form, but the right original documents must be sent by post. We prepare a complete application. Stamp 6 is especially useful for Irish citizens who live in Ireland but travel on another passport, for example because they also need it for work or family reasons. It makes your right to live in Ireland clear at the border.

Answers
Frequently asked questions
Stamp 6 is an endorsement placed in a non-Irish passport to show that the holder is an Irish citizen. It's for dual citizens who live in Ireland but use their other passport, for example because they don't have an Irish passport yet or prefer to travel on their other one. It tells immigration officers and others that the holder is Irish and can live in Ireland without any immigration conditions. There's no application form and no fee. The applicant writes to ISD's Stamp 6 Section in Dublin, sending the original documents for their route to citizenship. Someone who is Irish through a parent born in Ireland sends the parent's long-form civil birth certificate, the mother's civil marriage certificate if claiming through her, their own long-form birth certificate and their passport. Someone who is Irish through a grandparent sends their Foreign Births Registration certificate and passport, and a naturalised citizen sends their naturalisation certificate or Irish passport with their non-Irish passport. To renew Stamp 6 in a new passport, the applicant sends the expired passport with the stamp and the new passport. Documents are returned to a forwarding address, and ISD reports delays because of high volumes. Stamp 6 holders don't register with immigration. People who travel on an Irish passport don't need Stamp 6, and anyone who has given up Irish citizenship can't get it.
Not if you travel on your Irish passport. Stamp 6 helps when you live in Ireland and use your non-Irish passport.
Yes. Irish law doesn't require you to give up another citizenship, but some countries end their citizenship when you take another.
Yes. ISD returns them to the forwarding address you provide.
No. You're not eligible if you gave up Irish citizenship after a previous Stamp 6. See our Renounce or Reacquire Irish Citizenship service.
It's endorsed in your non-Irish passport, so it needs to be renewed when you get a new passport.
