For specific concerns or the most current legal requirements, it is best to consult a qualified attorney or refer directly to government agencies such as the Philippine Bureau of Immigration (BI) and the Department of Justice (DOJ).


1. Introduction

Naturalization is the legal process by which a foreign national acquires Philippine citizenship. In the Philippines, naturalization is governed by several laws and regulations that set forth both substantive (who is eligible) and procedural (how to apply) requirements. Understanding these laws is essential for any foreigner seeking to become a citizen of the Republic of the Philippines.


2. Legal Framework and Governing Laws

  1. 1987 Philippine Constitution

    • Defines who are citizens of the Philippines (by birth, descent, or naturalization).
    • Specifically gives Congress the power to enact laws pertaining to naturalization.
  2. Commonwealth Act No. 473 (Revised Naturalization Law)

    • The principal law enacted in 1939 that established the judicial process for naturalization.
    • Outlines the qualifications and disqualifications for naturalization through the courts.
  3. Republic Act No. 9139 (Administrative Naturalization Law of 2000)

    • Provides a more streamlined, administrative route for naturalization for certain aliens who have lived in the Philippines, studied here, and meet specific conditions.
    • Administered through the Special Committee on Naturalization (SCN) under the Department of Justice (DOJ).
  4. Other Relevant Laws and Issuances

    • Commonwealth Act No. 63 (as amended) concerning the ways by which Philippine citizenship may be lost or reacquired.
    • Republic Act No. 9225 (Citizenship Retention and Reacquisition Act of 2003) covers dual citizenship for natural-born Filipinos who have lost Philippine citizenship by naturalization in a foreign country (though this is more about reacquiring rather than obtaining citizenship for the first time).

3. Modes of Naturalization in the Philippines

3.1. Judicial Naturalization (Under Commonwealth Act No. 473)

Traditionally, foreigners seeking to be naturalized in the Philippines had to go through a court process, which involves filing a petition for naturalization with the Regional Trial Court (RTC). The process can be lengthy and requires compliance with detailed rules of procedure.

  1. Basic Eligibility Criteria (Commonwealth Act No. 473)

    • At least 21 years of age on the date of the petition.
    • Must have resided in the Philippines for a continuous period of at least ten (10) years (this may be reduced to five (5) years for certain applicants, such as those who have been married to a Filipino or have introduced a significant business or technology, but such exceptions apply under specific conditions).
    • Must be of good moral character and believe in the principles underlying the Philippine Constitution.
    • Must own real estate in the Philippines or have some known lucrative trade, profession, or lawful occupation.
    • Must be able to speak and write at least one of the principal Philippine languages (e.g., Filipino) and either English or Spanish.
    • Must have enrolled minor children of school age in recognized schools in the Philippines where Philippine history, government, and civics are taught or prescribed as part of the curriculum.
  2. Disqualifications

    • Those who do not meet age or residency requirements.
    • Persons with criminal convictions involving moral turpitude or offenses that reflect negatively on moral character.
    • Persons with mental or contagious diseases, or who could endanger public health or safety.
    • Citizens or subjects of nations with which the Philippines is at war, during the period of such war.
    • Polygamists or believers in polygamy (unless permitted by their recognized religious practice and under certain allowances given by law, though typically disqualifying under CA 473).
    • Those who have not fulfilled their tax obligations or who otherwise pose a security threat.
  3. Judicial Process Outline

    • Filing a Petition: The foreigner must file a petition for naturalization with the proper Regional Trial Court.
    • Publication/Posting Requirement: The petition and notice must be published in a newspaper of general circulation for a designated period (usually once a week for three consecutive weeks) and posted in public places.
    • Hearing: A court hearing is conducted where the petitioner presents evidence of eligibility (including witness testimonies attesting to good moral character and integration into Philippine society).
    • Decision: If granted, the court issues a decision stating that the petitioner is entitled to Philippine citizenship, subject to a two-year probation period in some cases.
    • Oath of Allegiance: After the decision becomes final, the petitioner must take the Oath of Allegiance to the Republic of the Philippines.
    • Issuance of Naturalization Certificate: The Bureau of Immigration (BI) will issue a Certificate of Naturalization. The petitioner may then apply for a Philippine passport and other official IDs.

3.2. Administrative Naturalization (Under Republic Act No. 9139)

Enacted in 2000, RA 9139 offers a less cumbersome alternative to judicial naturalization, but only for certain foreign nationals who meet specific criteria.

  1. Who May Qualify

    • Born in the Philippines and residing here since birth.
    • Must be at least 18 years old at the time of filing.
    • Of good moral character and has not been convicted of any crime involving moral turpitude.
    • Must have completed primary and secondary education in Philippine-recognized schools, where Philippine history, government, and civics are part of the curriculum.
    • Must have the ability to speak and write Filipino or any major regional Filipino language.
    • Must have a known, lawful, and lucrative means of support.
    • Must have mingled with Filipinos and evinced a desire to learn and embrace the customs, traditions, and ideals of the Filipino people.
  2. Filing an Application

    • An application is filed with the Special Committee on Naturalization (SCN) under the Department of Justice (DOJ).
    • Required supporting documents generally include:
      • Birth certificate
      • School records
      • Police clearance and NBI clearance
      • Barangay clearance
      • Proof of financial capacity
      • Other relevant documents proving the applicant’s ties and continuous residence in the Philippines
  3. Evaluation by the Special Committee on Naturalization (SCN)

    • The SCN evaluates the application, verifying compliance with all requirements.
    • A recommendation is sent to the Office of the President (OP).
    • Upon approval by the President, the applicant takes the Oath of Allegiance.
  4. Advantages of RA 9139 Over Judicial Naturalization

    • Faster and more streamlined administrative process.
    • No court hearings are involved.
    • Less expensive in terms of filing and legal fees.
    • However, eligibility is more restrictive because the applicant must have been born in the Philippines and must have completed both primary and secondary education in Philippine schools.

4. Typical Requirements for a Naturalization Application

While the specific documents may vary depending on whether the route is judicial or administrative, the following are commonly required:

  1. Birth Certificate (authenticated by the proper authorities, e.g., PSA for births recorded in the Philippines, or an equivalent document for foreign births).
  2. Marriage Certificate (if applicable), also duly authenticated.
  3. School Records (proof of enrollment and completion of education).
  4. Proof of Residency (immigration records, proof of continuous stay, ACR I-Card, visas, etc.).
  5. Police Clearance and NBI Clearance (to show no criminal record).
  6. Barangay Clearance (or local clearance showing good standing in the community).
  7. Affidavits of Witnesses attesting to good moral character, integration in the community, and knowledge of Filipino language/customs.
  8. Proof of Financial Capacity (employment certificate, business permits, income tax returns, etc.).
  9. Valid Identification (passport, Alien Certificate of Registration, etc.).

5. Steps in the Judicial Naturalization Process (Detailed)

  1. Preparation of the Petition

    • Consult with a lawyer to prepare a verified petition for naturalization.
    • Gather all necessary documents (see above).
  2. Filing with the Regional Trial Court

    • Pay the corresponding docket fees.
    • The petition is assigned a case number.
  3. Publication and Posting

    • The court issues an order directing the publication of the petition in a newspaper of general circulation once a week for three consecutive weeks.
    • Notices are posted in prominent places (e.g., courthouse, city or municipal hall).
  4. Hearing

    • The court sets a date for hearing after the publication requirement is satisfied.
    • The petitioner presents evidence and witness testimonies supporting eligibility.
    • The Office of the Solicitor General or a designated public prosecutor often appears to represent the government and ensure the applicant meets all legal requirements.
  5. Court Decision

    • If the court approves the petition, it issues a decision declaring the applicant eligible for Philippine citizenship, sometimes subject to a probationary period of two years.
  6. Oath of Allegiance

    • After the finality of the court’s decision (no appeals or objections), the applicant takes the Oath of Allegiance.
  7. Issuance of Naturalization Certificate

    • The Bureau of Immigration issues the Certificate of Naturalization upon receipt of the court’s final decision and oath.
    • The new citizen can then apply for a Philippine passport and other government-issued IDs.

6. Steps in the Administrative Naturalization Process (RA 9139)

  1. Application with the Special Committee on Naturalization (SCN)

    • Complete the prescribed application form and attach the required documents.
    • Pay the corresponding fees.
  2. Evaluation and Verification

    • The SCN reviews the application, may conduct interviews, and requests additional evidence or clarifications if needed.
  3. Decision and Presidential Approval

    • The SCN forwards a recommendation to the Office of the President.
    • If approved, the applicant is notified to take the Oath of Allegiance.
  4. Issuance of Certificate of Naturalization

    • Upon taking the Oath of Allegiance, the Certificate of Naturalization is granted.
    • The individual is then recognized as a Philippine citizen and may apply for a Philippine passport and other credentials.

7. Post-Naturalization Considerations

  1. Renunciation of Foreign Citizenship (If Required by the Foreign Country)

    • The Philippines generally does not require a person to renounce his/her original citizenship if the applicant is allowed dual citizenship by their country of origin.
    • However, some countries do not allow dual citizenship, and the applicant may need to renounce their original citizenship in compliance with their home country’s laws.
  2. Rights and Obligations

    • Naturalized citizens gain the same rights as Filipino citizens by birth, including the right to vote, to own land (subject to any constitutional limitations), and to engage in certain professions restricted to Filipino citizens.
    • They also have the same obligations, such as payment of taxes and adherence to Philippine laws.
  3. Dual Citizenship Issues

    • If you come from a country that permits dual citizenship (or has no restrictions on dual citizenship), you may retain your original citizenship even after becoming a naturalized Filipino.
    • If your country of origin does not allow dual citizenship, obtaining Philippine citizenship may cause you to lose your previous citizenship automatically under your home country’s laws.

8. Common Pitfalls and Tips

  • Incomplete Documentation: Failing to compile and submit all the necessary documents (e.g., birth certificates, clearances, proof of residency) can delay or derail the application.
  • Residency Requirements: Applicants must strictly comply with the residency requirements. Extended absences from the Philippines might reset or invalidate the continuous residency requirement.
  • Language and Cultural Familiarity: The requirement to speak a Philippine language and be familiar with local customs is often underestimated. Sincere efforts to learn and integrate can be crucial in demonstrating good moral character and intent.
  • Public Charge Concerns: Applicants need to prove that they have a stable income or livelihood. An inability to show a legitimate source of income can lead to denial.
  • Legal Advice: While it is not mandatory to hire a lawyer for administrative naturalization, having legal guidance is highly advisable, especially for the judicial route.

9. Conclusion

Obtaining Philippine citizenship through naturalization is a detailed legal process that requires meeting strict qualifications, preparing documentary evidence, and demonstrating genuine integration into Philippine society. Prospective applicants should carefully review the relevant laws—particularly Commonwealth Act No. 473 for judicial naturalization and Republic Act No. 9139 for administrative naturalization—to determine which route applies best to their circumstances.

Ultimately, acquiring Philippine citizenship opens the door to a host of rights and privileges, from voting in national and local elections to owning land and engaging in business freely within the country. Given the complexity of the process and the evolving nature of immigration policies, consulting an immigration lawyer or approaching authorized government agencies for accurate and up-to-date information is strongly recommended.
