In depth
Einbürgerung is the German term for naturalization — the process of acquiring German citizenship by application, as opposed to by birth (jus soli) or descent (jus sanguinis). Standard Einbürgerung requires 8 years of legal residence, German language proficiency (B1), and renunciation of other citizenships.
StAG §15 provides a special Einbürgerung path for victims of Nazi persecution and their descendants, with no residency or language requirement and no renunciation requirement. This complements Article 116 restitution.
StAG §14 provides for discretionary Einbürgerung of former Germans who lost citizenship and wish to regain it, with a residency requirement that can be waived.
