Verdict
Yes — you can hold Philippines and Germany citizenship simultaneously.
Philippines
Dual citizenship policy
Permitted — the Philippines allows full dual citizenship under RA 9225.
Germany
Dual citizenship policy
Permitted for Article 116 restitution and StAG §15 cases. For standard descent: generally requires renunciation, but 2024 dual citizenship reform now permits it.
Both Philippines and Germany permit dual citizenship. You can acquire, hold, and use both passports simultaneously without legal restrictions.
This assessment is based on each country's current nationality law. Dual citizenship rules can change — always verify with the relevant consulate or an immigration attorney before making decisions about renunciation or acquisition.
