I. Introduction

In the Philippines, citizenship is primarily governed by the 1987 Philippine Constitution and various statutory enactments. Over the years, the Philippine government has enacted legislation allowing former Filipinos who acquired foreign citizenship to regain or retain their Philippine citizenship under certain conditions. This policy aims to recognize the strong ties that Filipinos maintain with the motherland, even after moving abroad and adopting another nationality.

This article will outline:

The constitutional foundation for Philippine citizenship.
The key law enabling dual citizenship: Republic Act (R.A.) No. 9225.
Eligibility requirements for reacquisition and retention of Philippine citizenship.
The procedural steps for reacquiring or retaining citizenship.
Rights, obligations, and potential issues faced by dual citizens.
Other considerations when holding dual or multiple citizenships.

II. Constitutional and Legal Foundations

A. The 1987 Philippine Constitution

The 1987 Philippine Constitution, particularly Article IV, provides the basis for determining who are citizens of the Philippines. The following are considered Filipino citizens under Section 1 of Article IV:

Those who are citizens of the Philippines at the time of the adoption of the 1987 Constitution.
Those whose fathers or mothers are citizens of the Philippines (i.e., jus sanguinis, or bloodline principle).
Those born before January 17, 1973, of Filipino mothers, who elect Philippine citizenship upon reaching the age of majority.
Those who are naturalized in accordance with law.

Natural-Born Filipinos

Under the Constitution, natural-born citizens are those who are citizens of the Philippines from birth without having to perform any act to acquire or perfect their Philippine citizenship. This includes individuals born to at least one Filipino parent, even if they were born abroad.

B. Republic Act No. 9225 (Citizenship Retention and Re-Acquisition Act of 2003)

To address the growing diaspora and encourage former Filipinos to maintain legal ties with their homeland, Congress enacted Republic Act No. 9225, also known as the “Citizenship Retention and Re-Acquisition Act of 2003.”

Key points of R.A. 9225:

Eligibility: Only natural-born Filipinos who have lost their Philippine citizenship by naturalization in a foreign country are eligible to reacquire/retain their Philippine citizenship.
Dual Citizenship: R.A. 9225 recognizes that those who reacquire Philippine citizenship may still hold citizenship in another country (if that country’s laws permit dual citizenship).
Rights and Privileges: Those who reacquire Philippine citizenship under R.A. 9225 are entitled to the full civil, economic, and political rights enjoyed by Filipino citizens (with certain limitations for holding public office, discussed below).
Oath of Allegiance: Applicants must take an Oath of Allegiance to the Republic of the Philippines in a formal ceremony.

III. Who Is Eligible for Dual Citizenship Under R.A. 9225?

Natural-Born Filipinos who have lost Philippine citizenship due to acquiring foreign citizenship through naturalization.
Children of applicants (whether legitimate, illegitimate, or adopted) who are below 18 years of age are generally included as derivative beneficiaries of their parent’s reacquisition petition. They must still prove their Filipino lineage or relationship to the parent.

Note that Filipinos who were not natural-born (e.g., those who were naturalized as Filipinos) are not covered by R.A. 9225. However, such individuals may seek reacquisition under other legal avenues (e.g., regular naturalization laws).

IV. Retaining Original Nationality and the Concept of Dual Citizenship

Before R.A. 9225, Filipinos typically had to renounce their Philippine citizenship upon naturalizing in another country (depending on the laws of that country). R.A. 9225 removed the renunciation requirement, thereby allowing eligible natural-born Filipinos to retain or reacquire their Philippine citizenship.

Dual citizenship means that a person may hold two (or more) citizenships at once, subject to the laws of each country involved. While Philippine law under R.A. 9225 allows dual citizenship, the other country of citizenship may have its own restrictions—some nations (e.g., Japan, China) do not generally permit dual citizenship.

V. Requirements for Reacquiring Philippine Citizenship

When applying for reacquisition of Philippine citizenship under R.A. 9225, the typical documentary requirements include:

Proof of Philippine Citizenship:
- Philippine birth certificate (issued by the Philippine Statistics Authority or its predecessor, the National Statistics Office).
- Old Philippine passport, if available.
- Other documents showing that the applicant is a natural-born Filipino (e.g., Certificate of Naturalization as a Filipino, if applicable, or a foreign Birth Certificate indicating Filipino parentage).
Proof of Foreign Citizenship:
- Foreign passport.
- Certificate of naturalization in the foreign country.
Completed Application Forms:
- Forms vary slightly depending on whether you apply through a Philippine Consulate abroad or the Bureau of Immigration (BI) in the Philippines.
Oath of Allegiance:
- The applicant must swear allegiance to the Republic of the Philippines before a duly authorized Philippine official.
Fees:
- The consular or BI fees vary depending on jurisdiction and local rules.

Note: Minor children derived from the applicant’s reacquisition will also need proof of their relationship (e.g., birth or adoption certificate) and the relevant application forms, if they are being included under their parent’s petition.

VI. The Application Process

A. Application in the Philippines (Bureau of Immigration)

Submit Documents: File a petition for reacquisition under R.A. 9225. Provide supporting documents (proof of Philippine birth, proof of foreign citizenship, etc.).
Evaluation: The Bureau of Immigration evaluates the documents to confirm the applicant’s eligibility as a natural-born Filipino.
Oath of Allegiance: Upon approval, the applicant will be scheduled for the taking of the Oath of Allegiance.
Issuance of Certificate of Reacquisition: After taking the oath, the applicant receives a Certificate of Reacquisition (or Retention).

B. Application at a Philippine Consulate/Embassy Abroad

Set an Appointment or Walk-in: Procedures vary by consulate or embassy; check the official website for scheduling details.
Submit Documents and Pay Fees: Provide the completed form, proof of natural-born Philippine citizenship, proof of foreign citizenship, and any required fees.
Interview and Oath Taking: The consular officer administers an interview and, if the application is in order, schedules the Oath of Allegiance.
Issuance of Certificate: After taking the oath, the consulate issues the Certificate of Reacquisition/Retention of Philippine Citizenship.

VII. Rights, Privileges, and Obligations of Dual Citizens

Once Philippine citizenship is reacquired or retained, dual citizens generally enjoy the following:

Right to Reside in the Philippines: No need for a visa or special permit to enter or live in the Philippines indefinitely.
Right to Travel with a Philippine Passport: Dual citizens can hold both Philippine and foreign passports. When entering or exiting the Philippines, presenting the Philippine passport is often required (or recommended) to facilitate immigration procedures.
Right to Own Real Property: Philippine citizens have full rights to own land and property in the Philippines, subject to existing property laws.
Right to Engage in Business or Profession: Dual citizens may practice their profession in the Philippines (assuming compliance with professional regulatory requirements) and set up businesses subject to the same regulations as any Filipino citizen.
Political Rights:
- Right to Vote: Dual citizens can register and vote in Philippine elections (either in the Philippines or via overseas voting if abroad).
- Eligibility for Public Office: Natural-born Filipinos may hold certain elective offices, subject to residency requirements. However, individuals with dual citizenship who intend to hold public office (or serve in certain government positions) may be required by law to renounce their other citizenship before assumption of office.

VIII. Common Issues and Considerations

Conflict of Laws: Some countries do not recognize dual citizenship or impose restrictions. Before taking the Oath of Allegiance to the Philippines, applicants should verify if their foreign citizenship will be automatically nullified or require additional steps to maintain.
Taxation: Dual citizens might have tax obligations in multiple jurisdictions. Understanding cross-border taxation or seeking a tax professional’s advice is important.
Military Service: In certain countries, citizenship can entail compulsory military service. This is generally not the case in the Philippines at present, but individuals should research obligations in their other country of citizenship.
Renewal of Philippine Passport: A reacquired Filipino who wishes to hold a Philippine passport must follow standard passport application or renewal processes.
Children Born After Reacquisition: Children born after the parent has reacquired or retained Philippine citizenship typically inherit Filipino citizenship at birth, subject to the registration of the child’s birth at the Philippine Consulate or local civil registry in the Philippines.
Potential Renunciation for Public Office: Prospective candidates for certain public offices (e.g., legislative or executive positions) may need to formally renounce their non-Philippine citizenship, complying with constitutional or statutory requirements.

IX. Frequently Asked Questions

Can naturalized Filipinos (i.e., originally foreign nationals who became Filipino) apply for dual citizenship?
- R.A. 9225 specifically applies to natural-born Filipinos who lost Philippine citizenship through naturalization abroad. Naturalized Filipinos do not fall under this category but may avail themselves of other laws or reacquisition avenues.
How long does the process take?
- Processing times vary significantly based on the volume of applications and the applicant’s location (Philippines vs. abroad). In some Philippine Consulates, the entire process (submission, oath, and issuance of certificate) can be completed within a day or a few weeks, while in others, it may take longer.
Is there an age limit for applying?
- There is no specific maximum age limit, but an applicant must be of legal age to personally take the Oath of Allegiance. Minor children are included under the parent’s application.
Can I use my foreign passport when I leave or enter the Philippines?
- It is best practice for dual citizens to use the Philippine passport when entering or leaving the Philippines to avoid complications with immigration. In foreign airports, you typically use the foreign passport for exit/entry into that country.
Will reacquiring Philippine citizenship affect my pension or benefits in the foreign country?
- Generally, reacquisition of Philippine citizenship does not automatically forfeit foreign government pensions or benefits. However, the rules depend on each country’s laws and agreements.

X. Conclusion

Thanks to Republic Act No. 9225, natural-born Filipinos who have acquired foreign nationality can now retain or reacquire their Philippine citizenship. This legal framework aims to strengthen the bond between the global Filipino community and the Philippines, granting them the rights, privileges, and responsibilities of Filipino citizens once more.

Nevertheless, dual or multiple citizenship can present legal and practical issues, particularly when other countries have stricter citizenship laws. Anyone contemplating dual citizenship (or who has questions about property ownership, taxation, or eligibility for public office) is advised to consult relevant government agencies (e.g., the Bureau of Immigration, Philippine Consulates abroad) and/or seek professional legal counsel.
