A child born of Filipino parents in the United States is a FILIPINO. No qualifications, no ifs and buts. He may have also acquired American citizenship by accident of his place birth, but it doesn't diminish or cancel out his Philippine citizenship. https://twitter.com/themanilatimes/status/1264707963798933505

While he may appear to have two citizenships, from the point of view of Philippine law he has only ONE (his PH citizenship). The others are not for the Philippines to determine or take cognizance of. This is Art. 1 & 2 of the 1930 Convention on the Conflict of Nationality Law.

"Duals" need not do anything to perfect or complete their Philippine citizenships, as theirs are as complete and perfect as those born here.

They are also not required by R.A. No. 9225 to renounce their "dual" status as that law ONLY applies to Filipinos who naturalised abroad.

Lastly, once Philippine citizenship is acquired by blood, regardless where one is born, it can only be lost on the grounds listed in Commonwealth Act no. 63. Unless any of these grounds are proven in court, Philippine citizenship is presumed and it should never be a question.
