I think that if your father was (and/or still is) a US citizen, then you are also a US citizen no matter where you were born. It should be rather easy to get an american passport in the US embassy or consulate in the phillipines for you. As for your mother, I believe that she has to apply for a US visa or "green card" based on her marriage to your father who was/is a US citizen, or thru your US citizenship if you are over 21 years old.

The children of German citizens become German citizens on birth, regardless of the place of birth. Being born in Germany doesn't confer citizenship. Special conditions apply in the case of some ethnic Germans (outside Germany) and to the descendants of people stripped of German citizenship during the Nazi period.
