Information Evening on September 7 th , 2017 in Hamburg

Many Americans who have been living in Germany for many years are deterred from applying for German citizenship because of the German law requiring the renunciation of their American citizenship.

Almost 80 persons attended an information evening organized by the Hamburg Chapter of Democrats Abroad Germany to shed light on the subject.  What are the rules and regulations?  Where can I get more specific information concerning my situation?
Two officials from the Hamburg Naturalization Office presented the facts and answered questions. 
Here is their presentation, in German.
