Recognition of Citizenship

Today January 19 2011, my papa finally got the time to pay a visit to the Bureau of Immigration in Intramuros, Manila.
Dad was working on something and he took the time to inquire on my documentary requirements at the Bureau.
Upon arrival at the Manila International Airport from the U.S., when the immigration stamped the arrival seal on my U.S. passport, she noted that my parents had Philippine passports.
The immigration officer told us to pay the Bureau of Immigration a visit, as I need to be recognized as having Philippine citizenship.
Otherwise, I would be deemed an alien (being a bearer of a U.S. passport), and would be subject to rules for aliens visiting the Philippines.
It was only today that my father was able to visit the immigration bureau .
It was gathered that I need to be recognized as a Filipino citizen, aside from having a U.S. citizenship.
I need to apply for recognition of Philippine citizenship.
Of course my father would have to do it in my behalf, since I am a minor (infant as a matter of fact).
The documents required are:
(1) Noarized request for recognition
(2) NSO certified Report of Birth of the minor-applicant
(3) NSO birth certificate of the parents
(4) Affidavit of citizenship
(5) Photocopies of the passport of parents and the applicant
