Citizenship can be revoked under Section 19 of the Irish Nationality and Citizenship Act 1956 in the event of wrongdoing or injury to others.
Aside from that, if you have an Irish passport and live in another country, you must renounce your Irish citizenship in order to apply for citizenship there. Dual citizenship is permitted in many nations, but it is not permitted in Ireland. A person who has acquired Irish citizenship has the option of having it revoked and applying for citizenship in another nation.
But just like the difficult process of filling out an Irish citizenship application, there can be complications here. To avoid any hassle, professional assistance will help. Although citizenship cannot be lost by the operation of law, foreign law may require a person to renounce their Irish citizenship before acquiring another nationality.
