The exercise of civil rights is independent of the quality of citizen, which is only acquired and preserved conformably to the constitutional law. Every Frenchman shall enjoy civil rights. Every individual born in France of a foreigner, may, during the year which shall succeed the period of his majority, claim the quality of Frenchman; provided, that if he shall reside in France he declares his intention to fix his domicil in that country, and that in case he shall reside in a foreign country, he give security to become domiciled in France and establish himself there within a year, to be computed from the date of that undertaking.
