German citizenship work built around law, records and evidence
Hannover has worked on German citizenship cases since 2015. Its work brings together research in German and American archives, the preparation of files for the German authorities, and the analysis of German nationality law.
Our work
A German citizenship case usually depends on two disciplines. The first is the correct reconstruction of the family line from the records: births, marriages, emigration, naturalization, consular registration. The second is the correct application of German nationality law as it stood at each moment of that history, from the act of 1870 to the provisions in force today.
Hannover brings the two together in one structure. Genealogists and case managers find and prepare the evidence; the questions of law that the evidence raises are examined within the same case, by the person responsible for them.
Hannover German Citizenship, LLC is the group's United States company. It carries out archive research, genealogical reconstruction, translation and legalization, the assembly of applications in the form the German authority requires, filing, and follow-up until the file is decided.

How the file reaches Germany
For applicants living outside Germany, German citizenship procedures of this kind are generally handled by the Bundesverwaltungsamt (BVA) in Cologne. Hannover keeps an address for service of documents in that city, so that correspondence and formal notices reach it in the country where the file is decided.
The group also serves families in Brazil and Portugal, and its Austrian citizenship work is done under a separate name.
How this started
In 2001 Fabio Werlang travelled to Germany to look for the records of his own German ancestors, in several regions of the country. With those documents, and after studying the nationality legislation from 1870 onwards, he obtained confirmation of his own German citizenship from the Bundesverwaltungsamt.
Hannover was founded in April 2015, when the demand for that kind of work turned out to be much larger than one family. The American company followed, for families in the United States.
