There is no express guidance in the Irish Nationality and Citizenship Act 1956 about absences from the state after the lodgement of the Naturalization application.
They’re very clear in the guidelines before the application is lodged, which is continuous residence. KOD Lyons Solicitors advise that you have to be continuously resident in the jurisdiction so that you’re in compliance with your conditions and any exceptional absences from the state really should be notified to the minister during the currency of your application.
