Depositary: Secretary General for the United Nations

The Contracting States,
ACTING in pursuance of resolution 896 (IX), adopted by the General Assembly of the United Nations on 4 December 1954, 
CONSIDERING it desirable to reduce statelessness by international agreement, 
HAVE AGREED as follows: 
Article 1
1. A Contracting State shall grant its nationality to a person born in its territory who would otherwise be stateless. Such nationality shall be granted: 
(a) At birth, by operation of law, or 
(b) Upon an application being lodged with the appropriate authority, by or on behalf of the person concerned, in the manner prescribed by the national law. Subject to the provisions of paragraph 2 of this article, no such application may be rejected. A Contracting State which provides for the grant of its nationality in accordance with subparagraph (b) of this paragraph may also provide for the grant of its nationality by operation of law at such age and subject to such conditions as may be prescribed by the national law. 
2. A Contracting State may make the grant of its nationality in accordance with subparagraph (b) -of paragraph I of this article subject to one or more of the following conditions: 
(a) That the application is lodged during a period, fixed by the Contracting State, beginning not later than at the age of eighteen years and ending not earlier than at the age of twenty-one years, so, however, that the person concerned shall be allowed at least one year during which he may himself make the application without having to obtain legal authorization to do so; 
(b) That the person concerned has habitually resided in the territory of the Contracting State for such period as may be fixed by that State, not exceeding five years immediately preceding the lodging of the application nor ten years in all; 
(c) That the person concerned has neither been convicted of an offence against national security nor has been sentenced to imprisonment for a term of five years or more on a criminal charge; 
(d) That the person concerned has always been stateless. 
3. Notwithstanding the provisions of paragraphs I (b) and 2 of this article, a child born in wedlock in the territory of a Contracting State, whose mother has the nationality of that State, shall acquire at birth that nationality if it otherwise would be stateless. 
4. A Contracting State shall grant its nationality to a person who would otherwise be stateless and who is unable to acquire the nationality of the Contracting State in whose territory he was born because he has passed the age for lodging his application or has not fulfilled the required residence conditions, if the nationality of one of his parents at the time of the person's birth was that of the Contracting State first above-mentioned. If his parents did not possess the same nationality at the time of his birth, the question whether the nationality of the person concerned should follow that of the father or that of the mother shall be determined by the national law of such Contracting State. If application for such nationality is required, the application shall be made to the appropriate authority by or on behalf of the applicant in the manner prescribed by the national law. Subject to the provisions of paragraph 5 of this article, such application shall not be refused. 
5. The Contracting State may make the grant of its nationality in accordance with the provisions of paragraph 4 of this article subject to one or more of the following conditions: 
(a) That the application is lodged before the applicant reaches an age, being not less than twenty-three years, fixed by the Contracting State; 
(b) That the person concerned has habitually resided in the territory of the Contracting State for such period immediately preceding the lodging of the application, not exceeding three years, as may be fixed by that State;

Article 4
1. A Contracting State shall grant its nationality to a person, not born in the territory of a Contracting State, who would otherwise be stateless, if the nationality of one of his parents at the time of the person's birth was that of that State. If his parents did not possess the same nationality at the time of his birth, the question whether the nationality of the person concerned should follow that of the father or that of the mother shall be determined by the national law of such Contracting State. Nationality granted in accordance with the provisions of this paragraph shall be granted: 
(a) At birth, by operation of law, or 
(b) Upon an application being lodged with the appropriate authority, by or on behalf of the person concerned, in the manner prescribed by the national law. Subject to the provisions of paragraph 2 of this article, no such application may be rejected.

Article 7
1.	(a) If the law of a Contracting State entails loss or renunciation of nationality, such renunciation shall not result in loss of nationality unless the person concerned possesses or acquires another nationality; 
(b) The provisions of subparagraph (a) of this paragraph shall not apply where their application would be inconsistent with the principles stated in articles 13 and 14 of the Universal Declaration of Human Rights approved on 10 December 1948 by the General Assembly of the United Nations.
