Detailed description
If you need official proof that you do not have German citizenship, you can submit an application to determine that you do not have German citizenship. If all the requirements are met, you will then receive a so-called negative certificate.
You will need this certificate, for example, if an authority abroad - such as in your country of origin or the country of origin of your parents - requires such proof. This certificate may also be required for certain consular services provided by a foreign representation of another country in Germany.
