The Promise (2016 German film): The Promise (original title: "Das Versprechen") is a German documentary film directed by Marcus Vetter with Karin Steinberger.  The film tells the crime story of the double murder of Derek and Nancy Haysom on 30 March 1985 in Lynchburg, Virginia.  The film focuses on the two main protagonists Jens Söring, son of a German diplomat, and Elizabeth Haysom, the daughter of the murdered couple.  Both were sentenced to life in prison.  The film makes use of extensive original footage from press archives, as the two court cases were the first lawsuits to be broadcast nationwide on American television.  In the film, these recordings from 1985 to 1990 are combined with scenes shot during the making of the film, including interviews with Jens Söring, witnesses, the investigators involved in the case, lawyers, prosecutors and journalists.  In addition, extensive materials such as original crime scene photos and evidence, court transcripts, newspaper archives, love letters and diaries of the two main protagonists were evaluated in the film.

German nationality law: German nationality law is the law governing the acquisition, transmission and loss of German citizenship.  The law is based on a mixture of the principles of "jus sanguinis" and "jus soli".  In other words, one usually acquires German citizenship if a parent is a German citizen, irrespective of place of birth, or by birth in Germany to parents with foreign nationality if certain requirements are fulfilled.  Naturalisation is also possible for foreign nationals after six to eight years of legal residence in Germany.  However, non-EU and non-Swiss citizens must usually renounce their old citizenship before being naturalised in Germany.  Citizens of other EU countries and of Switzerland usually can keep their old citizenship.  Some EU countries do not allow dual citizenship even with other EU countries.  German citizens wanting to acquire a non-EU or non-Swiss citizenship and to maintain their German citizenship must apply for a permission ("Beibehaltungsgenehmigung") before acquiring the other citizenship, or they will automatically lose their German citizenship when they acquire the foreign citizenship.  For details, see section "Dual citizenship."

German passport: German passports are issued to nationals of Germany for the purpose of international travel.  A German passport is, besides the German ID card and the German Emergency Travel Document (called ""), the only other officially recognised document that German authorities will routinely accept as proof of identity from German citizens.  Besides serving as proof of identity and presumption of German nationality, they facilitate the process of securing assistance from German consular officials abroad (or other EU-members in the case that a German consular facility is absent).  German passports are valid for ten years (for people older than 24) or six years (for people until the age of 24) and share the standardised layout and burgundy red design with other EU passports. Every German citizen is also a citizen of the European Union.  The passport, along with the national identity card allows for free rights of movement and residence in any of the states of the European Union and European Economic Area.
