Answer:
Birth and Naturalization

There are two main systems used to determine citizenship as of the time of birth: jus soli, whereby citizenship is acquired by birth within the territory of the state, regardless of parental citizenship; and jus sanguinis, whereby a person, wherever born, is a citizen of the state if, at the time of his or her birth.
The Philippine nationality law is based upon the principles of jus sanguinis (Latin for right of blood) and therefore descent from a parent who is a citizen or national of the Republic of the Philippines is the primary method of acquiring Philippine citizenship.
