What are the modes of acquiring Filipino citizenship?
There are two (2) generally recognized modes of acquiring Philippine citizenship
1) by birth; and
1) Jus soli (right of soil) which is the legal principle that a person's nationality at birth is determined by the place of birth (ie, the territory of a given state).
2) Jus sanguinis (right of blood) which is the legal principle that, at birth, an individual acquires the nationality of his/her natural parent/s. The Philippines adheres to this principle.
2) by naturalization which is the judicial act of adopting a foreigner
and clothing him with the privileges of a native-born citizen. It implies the renunciation of a former nationality and the fact of entrance into a similar relation towards a new body politic. (2 Am.Jur.561, par.188)
