In order to officially obtain German nationality, a German descendant must apply for
recognition of German nationality. If the application is approved, you will receive a
German citizenship certificate, i.e. a certificate confirming that you are a German citizen.
This process is different from a naturalization process, since in this case it will only be
officially confirmed that you have had German citizenship since birth, due to your direct
descent from Germans. The German citizenship certificate is not equivalent to a German
birth certificate, but with it you can apply for a German passport.
