§ 81 Abs. 4 of the AufenthG
If a foreigner applies for an extension of his or her residence title or for a different residence title before his or her current residence title expires, the current residence title is deemed to remain in force from the time it expires until the time of the decision by the foreigners authority. This does not apply to visas issued in accordance with section 6 (1). If the application to issue or extend a residence title was filed too late, the foreigners authority may order that the previous residence title remains valid in order to avoid undue hardship. –Â Â Gesetze im Internet

If the male or female applicant is lawfully resident without a visa in the Federal Republic, because he or she is entitled to be by virtue of his/her nationality, the fictional certificate will be issued in accordance with § 81 Section 3 of the Residence Act.
