German passports (Reisepass) where issued by the town of which a person was a citizen. In 1950 Germany started issuing national passports, but they were and are processed at the town level.
To this day German's are citizens first of the town where they were born and vital records are kept at the town level. If she and or her parents were considered repatriated Germans during the 1930's through WWII, there may be records of their obtaining German citizenship among the captured German records at the National Archives in College Park MD. Depending on the occupations that her parents had in Germany they may have been required to join the Nazi party and those records are also NARA College Park, MD. You would have to look both for records from the town where she was born and the town where she lived in Germany.
In accordance to your grandmothers Petition for Naturalization available for example on ancestry she was a citizen of Germany and she arrived in 1958. It is now necessary to know where she lived in Germany. Unfortunately it is not that easy to find otherwise an application for a passport. If these types of records still exist, they might be in the state archive of the state your grandmother lived, but today for example passport records are kept just for the time the issued passport will expire. So I would contact the state archive of the state where your grandmother lived and would ask whether these records or better which records are still available.

Dear Ms. Turolla,
Thank you for posting your request on History Hub!
Along with the previous posters, we suggest that you request your grandmother’s naturalization records that may include information about her specific location in Germany, which you then may use to request her passport and citizenship information from the local German authorities.
Certificates of citizenship were issued by the Federal courts until October 1991 when INS took over responsibility for naturalization proceedings. All INS records are now overseen by the US Citizenship and Immigration Services (USCIS). USCIS maintains duplicate copies of court records (including the certificate of citizenship) created since September 27, 1906. Beginning April 1, 1956, INS began filing all naturalization records in a subject’s Alien File (A-File), which can be requested through the USCIS Genealogy Program.
In addition, the FamilySearch research wiki for German Genealogy may be useful.
We hope this is helpful. Best of luck with your research!
