All Foreign Births Register FAQsYou can apply if you were born outside Ireland and either one of your grandparents was born on the island of Ireland, or one of your parents was an Irish citizen at the time of your birth even though they were not born in Ireland. Once you are entered on the register you are an Irish citizen and can apply for an Irish passport.
More detailNo. If one of your parents was born on the island of Ireland and was an Irish citizen when you were born, you are already an Irish citizen, automatically. You do not need Foreign Birth Registration and can apply for an Irish passport directly.
More detailNot directly. A great-grandparent only helps if your parent had already been entered on the Foreign Births Register before you were born, in which case you apply through your parent. If your parent registered after your birth, you cannot apply through them. Applications based on Irish descent or associations beyond that are a separate route, decided at the discretion of the Minister for Justice.
More detailAbout 12 months to process a complete application. Applications are handled in strict date order, and incomplete applications are returned without being processed.
More detailThe fee is €278 for adults (€270 for registration and the certificate, plus a non-refundable €8 postage and handling fee) and €153 for under-18s (€145 plus €8). It is paid online when you submit your application.
More detailNot for Ireland. Irish law allows dual citizenship, so you can become an Irish citizen and keep your other citizenship. Some countries do not allow dual citizenship, so check the rules of your other country of nationality.
