Algerian nationality law is regulated by the Constitution of Algeria, as amended; the Algerian Nationality Code, and its revisions; and various international agreements to which the country is a signatory. These laws determine who is, or is eligible to be, a national of Algeria. The legal means to acquire nationality, formal legal membership in a nation, differ from the domestic relationship of rights and obligations between a national and the nation, known as citizenship. Algerian nationality is typically obtained under the principle of jus sanguinis, i.e. by birth in Algeria or abroad to parents with Algerian nationality. It can be granted to persons with an affiliation to the country, or to a permanent resident who has lived in the country for a given period of time through naturalisation.
Nationality can be acquired in Algeria through birth or naturalization.
Persons born to at least one parent with Algerian nationality; or
Foundlings born in the territory of unknown parentage.
Naturalization can be granted to persons who have resided in the territory for a sufficient period of time, seven years, to confirm they understand the customs and traditions of the society. General provisions are that applicants be of good character and in good health, have no criminal history, and are able to support themselves. If nationality is being considered for exceptional service to the nation, there can be no limiting conditions. In the case of a foreign spouse, a couple must have been married for three years and have established a two year residency to apply for naturalization. Muslim law in Algeria prevents full adoption of children. This lack of a legal parent-child relationship means that children who have been assigned guardians under the Islamic adoptional jurisprudence, known as kafala, are unable to inherit from a guardian and thus cannot derive parental nationality.
Algerians are allowed to renounce their nationality, provided they will not be rendered stateless, but must have permission to do so.
