Presently, one may acquire Algerian citizenship by birth in Algeria or abroad when born to at least one parent who is an Algerian citizen.
In terms of acquiring Algerian nationality after birth, this is possible through marriage with an Algerian citizen, through naturalisation and by exemption for foreigners who have rendered exceptional services to Algeria. The foreigner whose infirmity or sickness has been contracted in the service or in the interest of Algeria, and the foreigner whose naturalisation is of exceptional interest to Algeria, may also be granted Algerian citizenship.
Where an applicant is married to an Algerian citizen, the acquisition of citizenship is subject to proof that the marriage is legal and established for three years, the individual in question has had lawful residence in Algeria of at least 2 years, is of good character, and is able to justify livelihood.
To satisfy the requirements for naturalisation, the foreigner must show his/her assimilation into the Algerian community, show proof of lawful residence in Algeria for at least 7 years before the date of application, must be of good character, justify sufficient livelihood, and have a healthy body and spirit.
With respect to dual citizenship, this is allowed in Algeria and any Algerian citizen acquiring second citizenship will not lose their original citizenship. Reciprocally, foreign nationals who acquire Algerian citizenship are not required to renounce their original nationality, following the repeal of Article 3 in the National Code amendment of 2005. Algerian citizens are not required to register or justify their dual citizenship status.
