Naturalization is the legal act of adopting an alien and clothing him with the privilege of a natural-born citizen. A person may be naturalized either by complying with both the substantive and procedural requirements of general naturalization law or he may be naturalized by a special act of the legislature (The 1987 Philippine Constitution A Reviewer-Primer, Joaquin G. Bernas, S.J., 3rd Edition, Page 200.)

Below are the substantive requirements of the law on naturalization and acquisition of Filipino citizenship.

1. He must be not less than twenty-one years of age on the day of the hearing of the petition;

2. He must have resided in the Philippines for a continuous period of not less than ten years;

3. He must be of good moral character and believes in the principles underlying the Philippine Constitution, and must have conducted himself in a proper and irreproachable manner during the entire period of his residence in the Philippines in his relation with the constituted government as well as with the community in which he is living.

4. He must own real estate in the Philippines worth not less than five thousand pesos, Philippine currency, or must have some known lucrative trade, profession, or lawful occupation;

5. He must be able to speak and write English or Spanish and any one of the principal Philippine languages; and

6. He must have enrolled his minor children of school age, in any of the public schools or private schools recognized by the Office of Private Education of the Philippines, where the Philippine history, government and civics are taught or prescribed as part of the school curriculum, during the entire period of the residence in the Philippines required of him prior to the hearing of his petition for naturalization as Philippine citizen.”

You must therefore satisfy all the required qualifications before you can file your petition for naturalization. You must show proof that you resided in the Philippines for at least ten years before you can file your petition for naturalization. However, the ten-year residence’ requirement may be reduced into five years if the person filing the petition is married to a Filipino citizen (Section 3 of C.A. No. 473).

Any person desiring to acquire Philippine citizenship shall file with the competent court, a petition in triplicate, signed by him in his own handwriting, accompanied by his two photographs setting forth, the following:

1. His name and surname;

2. His present and former places of residence;

3. His occupation;

4. The place and date of his birth;

5. Whether single or married and the father of children, the name, age, birthplace and residence of the wife and of each of the children;

6. The approximate date of his or her arrival in the Philippines, the name of the port of debarkation, and, if he remembers it, the name of the ship on which he came;

7. A declaration that he has the qualifications required by this Act, specifying the same, and that he is not disqualified for naturalization under the provisions of this Act; that he has complied with the requirements of Sec. five of this Act;

8. And that he will reside continuously in the Philippines from the date of the filing of the petition up to the time of his admission to Philippine citizenship (Section 7 of C.A. 473).

The petition may be filed in the proper Regional Trial Court of the province or city in which the petitioner is residing for at least one year immediately preceding the filing of the petition (Section 8 of C.A. No. 473).
