Philippines Citizenship of child born in the US with a Philippines Citizen mother and a US Citizen father: Process and fees

i have a question, I know that under the principle of jus sanguinis which the Philippines has,which means that those who were born of Filipino fathers or mothers are considered citizens of the Philippines. If a baby is born here in the US, with a USC father and Philippines Citizen mother, by virtue of the doctrine of jus soli ( here in the US ) the baby is likewas a US citizen. There is no need to for the to child recognized as a Philippine citizen because the constitution itself grants im/her the Philippines Citizenship through jus sanguinis. So my question now is, how will the Child get a recognition of his Philippines Citizenship? Anybody knows he process and so as the fees to include? - Thank you everyone!

inquire at the philippine consulate how you will report the birth.
