The application for dismissal must be submitted to the competent district administrative authority (district administration office/independent city).
The certificate of dismissal is issued by the competent authority after the prerequisites and reasons for refusal have been checked.
The dismissal from German citizenship becomes effective on the day the dismissal certificate is handed over, which is done by the competent authority. Please note that from this date you will be treated as a foreigner by German authorities. Upon delivery, your German passport and/or identity card will be confiscated.
However, the dismissal will become retroactively invalid if you have not acquired the requested foreign citizenship within one year after the issuance of the dismissal certificate. In this case, you will continue to be considered a German citizen (again). In this case, please contact your competent authority immediately. If you are abroad at this time, this is the respective German mission abroad or directly the Federal Office of Administration.
As an active civil servant, judge, soldier or otherwise in a public-law employment relationship, you cannot be dismissed from German citizenship.
Dismissal from German citizenship may also affect an existing public employment relationship (Beamtenverhältnis), or current or future pension benefits (e.g. retirement pension / pension benefits, orphan's, widow's benefits).
Before submitting your application, please inquire with your employer or your benefits office whether and to what extent you will suffer any (financial) disadvantages as a result of giving up your German citizenship.
