Former Filipinos who became naturalized citizens of another country can usually regain Philippine citizenship without giving up their present nationality. The process is commonly called “applying for dual citizenship,” but the legal mechanism is more specific: a qualified former natural-born Filipino takes an oath of allegiance under Republic Act No. 9225. The most important questions are whether you were natural-born, how you acquired foreign citizenship, and whether your Philippine records can prove your identity and former citizenship.
What dual citizenship under RA 9225 means
Republic Act No. 9225, or the Citizenship Retention and Re-acquisition Act of 2003, allows certain natural-born Filipinos to retain or reacquire Philippine citizenship after becoming naturalized citizens of another country.
The law distinguishes between two situations:
- Retention of citizenship generally applies when a natural-born Filipino became a foreign citizen after RA 9225 took effect.
- Reacquisition of citizenship generally applies when the person had already lost Philippine citizenship through foreign naturalization before the law took effect.
In practice, both involve filing a petition, proving that the applicant was a natural-born Filipino, and personally taking the prescribed oath of allegiance to the Republic of the Philippines. Once the oath and approval requirements are completed, the applicant is again treated as a Philippine citizen under Philippine law. (Supreme Court E-Library)
RA 9225 does not create a general right to dual citizenship for every person with Filipino ancestry. It mainly covers former natural-born Filipinos who lost Philippine citizenship because they became naturalized citizens of another country.
Who is eligible for dual citizenship as a former Filipino?
You generally qualify under RA 9225 when all the following are true:
- You were a natural-born citizen of the Philippines.
- You lost Philippine citizenship because you were naturalized as a citizen of a foreign country.
- You are willing to take an oath of allegiance to the Philippines.
- You can provide satisfactory documents proving your identity, Philippine birth or parentage, and foreign naturalization.
What does “natural-born Filipino” mean?
Under Article IV of the 1987 Philippine Constitution, natural-born citizens are citizens of the Philippines from birth who did not have to perform an act to acquire or perfect their citizenship.
This generally includes:
- A person born to a Filipino father or mother under the 1987 Constitution.
- A person born on or after January 17, 1973, whose father or mother was a Philippine citizen at the time of birth.
- A person born before January 17, 1973, to a Filipino mother who properly elected Philippine citizenship under the applicable constitutional rules.
- A person whose Philippine citizenship from birth can be established through an applicable earlier Constitution.
Citizenship in the Philippines is primarily based on jus sanguinis, meaning citizenship by blood or parentage, rather than merely being born within Philippine territory. (Lawphil)
Who may need a different process?
| Situation | Likely procedure |
|---|---|
| Natural-born Filipino who became a naturalized foreign citizen | Petition under RA 9225 |
| Person born abroad while a parent was still a Philippine citizen | Report of Birth, Philippine passport application, or recognition as a Filipino citizen |
| Foreign citizen with a Filipino grandparent, but neither parent was Filipino at the time of birth | Usually not eligible under RA 9225 based only on the grandparent |
| Former Filipino who expressly renounced Philippine citizenship rather than losing it through foreign naturalization | Eligibility must be evaluated under other citizenship laws; RA 9225 may not automatically apply |
| Foreign spouse of a Filipino or dual citizen | Immigration or naturalization process, not derivative citizenship under RA 9225 |
| Former natural-born Filipino who wants permanent Philippine residence but not citizenship | A returning former Filipino immigrant visa under Section 13(g) may be considered |
A person born abroad to a Filipino parent may already have been a Philippine citizen from birth. In that situation, applying under RA 9225 may be unnecessary or procedurally incorrect. The Bureau of Immigration has a separate recognition as a Filipino citizen procedure for certain people whose Filipino citizenship must be formally documented. (Bureau of Immigration Philippines)
Legal effect of taking the oath under RA 9225
The central legal act is the applicant’s oath of allegiance. The oath is not merely ceremonial. It is the statutory act through which a qualified person retains or reacquires Philippine citizenship.
The applicant promises to:
- Support and defend the Constitution of the Philippines.
- Obey Philippine laws and lawful orders.
- Recognize the authority of the Philippines.
- Maintain faith and allegiance to the Republic.
Under Philippine law, applicants are not ordinarily required to surrender or renounce their foreign citizenship as part of a standard RA 9225 application. Whether the applicant may keep the foreign citizenship, however, also depends on the law of the other country. Some countries freely recognize multiple citizenships, while others restrict or penalize acquiring or exercising another nationality. Applicants should verify the current nationality law of their foreign country before taking the oath.
Rights restored after reacquiring Philippine citizenship
A person approved under RA 9225 generally regains the civil and political rights attached to Philippine citizenship, subject to constitutional and statutory requirements.
These may include the right to:
- Apply for and use a Philippine passport.
- Reside indefinitely in the Philippines without an immigration visa.
- Own land in the Philippines, subject to constitutional and legal limitations.
- Engage in business or investment activities open to Philippine citizens.
- Practice a regulated profession after obtaining the required Philippine license or authority.
- Register and vote if the person meets the applicable election and overseas voting requirements.
- Transmit Philippine citizenship to a child born while the parent is a Philippine citizen.
Reacquiring citizenship does not automatically activate every right without further paperwork. For example, a dual citizen must still register as a voter, qualify for a professional license, properly document a child’s birth, and obtain a Philippine passport before relying on that passport for travel.
Running for public office or accepting a government position
RA 9225 imposes additional requirements on dual citizens who seek elective or appointive public office.
A person running for elective office must:
- Meet all constitutional and statutory qualifications for the position; and
- Make a personal and sworn renunciation of all foreign citizenship when filing the certificate of candidacy.
A person accepting an appointive public office must generally renounce the oath of allegiance previously made to the foreign country, in addition to taking the oath required for the Philippine position.
These requirements are stricter than the ordinary RA 9225 oath. In Maquiling v. Commission on Elections, the Supreme Court treated the use of a foreign passport after a sworn renunciation as conduct inconsistent with the renunciation for election purposes. Dual citizens considering public office should therefore avoid assuming that an RA 9225 approval alone is sufficient. (Supreme Court E-Library)
Documents needed for a dual citizenship application
Exact requirements differ among Philippine embassies, consulates, and Bureau of Immigration offices. Most applicants should prepare the following:
| Document | Practical notes |
|---|---|
| Accomplished RA 9225 petition form | Use the form required by the particular embassy, consulate, or BI office |
| Recent passport photographs | Size, background, clothing, and number of copies vary by office |
| PSA-issued Philippine birth certificate | Usually the main proof of birth and natural-born status |
| Old Philippine passport | Submit the original or copies if available; explain loss or unavailability through an affidavit when required |
| Current foreign passport | Bring the original and photocopies of the information and signature pages |
| Foreign naturalization certificate | Shows how and when foreign citizenship was acquired |
| Marriage certificate | Required when the applicant’s name changed through marriage |
| Court order, divorce decree, or death certificate | May be needed to explain later civil-status or name changes |
| Affidavit explaining discrepancies | Commonly required for differences in names, dates, places of birth, or parents’ information |
| Documents for minor children | Birth certificates, passports, photographs, proof of relationship, and citizenship records |
| ACR I-Card or alien registration records | Relevant when applying in the Philippines as a registered foreign national |
The Bureau of Immigration publishes the standard petition and dependent forms on its official BI forms page. (Bureau of Immigration Philippines)
Foreign-language and foreign-issued documents
Documents not written in English or Filipino normally require a certified English translation. Depending on the issuing country and the instructions of the receiving office, a foreign public document may also need:
- An apostille issued by a competent authority of a country that is a party to the Apostille Convention; or
- Authentication or legalization through the appropriate government and Philippine foreign-service channels when the issuing country does not use the Apostille Convention.
Private documents, such as affidavits, may first need notarization before they can be apostilled. Always follow the document rules of the embassy, consulate, or BI office handling the petition because requirements can differ according to the country where the document originated. The Philippine Embassy’s apostille guidance explains the general treatment of foreign documents intended for use in the Philippines. (Philippine Embassy)
How to apply for dual citizenship outside the Philippines
Applications abroad are processed through the Philippine embassy or consulate that has jurisdiction over the applicant’s residence.
Identify the correct Philippine foreign-service post. Check the official website of the Philippine embassy or consulate responsible for your state, province, territory, or country. Do not assume that the nearest physical office has jurisdiction over your address.
Download the post’s current checklist and application form. Consular posts may impose their own appointment, mailing, photograph, payment, and photocopy requirements.
Obtain a recent PSA birth certificate. Request the correct record before scheduling the oath. A local civil registrar certificate may not be accepted as a substitute when the post requires a PSA-issued copy.
Resolve name and civil-status discrepancies. Prepare marriage records, court orders, divorce documents, death certificates, or affidavits explaining why your present name differs from the Philippine birth record.
Submit the documents for pre-evaluation. Some posts require advance mailing or electronic submission. Others evaluate the application during a scheduled personal appointment.
Appear personally for the interview and oath. The principal applicant must ordinarily appear before a Philippine consular officer. Do not sign the petition or oath in advance when the post instructs applicants to sign in the officer’s presence.
Pay the required consular fees. Payment methods may be limited to cash, money order, cashier’s check, or another method specified by the post.
Receive the approval documents. These commonly include an identification certificate, order of approval, oath of allegiance, or certificate of retention or reacquisition.
Apply separately for a Philippine passport. Reacquisition of citizenship and passport issuance are separate processes, even when the applications can be handled during the same consular visit.
For example, the Philippine Consulate General in New York requires personal appearance, documentary proof of Philippine birth and foreign naturalization, current passports, civil-status records where applicable, and separate documents for dependent minor children. Other posts may use different appointment systems and checklists. (Philippine Consulate General)
How to apply for dual citizenship in the Philippines
A qualified applicant who is physically in the Philippines may file through the Bureau of Immigration.
- Download and complete the correct BI petition form.
- Compile the documentary checklist.
- Submit the petition to the designated BI receiving office.
- Present the original documents for verification.
- Obtain the Order of Payment Slip.
- Pay the assessed government fees and keep the official receipt.
- Take the oath of allegiance when instructed.
- Wait for evaluation and approval by the authorized BI office.
- Claim the order of approval, oath, and certificate of retention or reacquisition.
- Request cancellation of foreigner registration records when applicable.
A registered alien should disclose any Alien Certificate of Registration Identity Card, Immigrant Certificate of Residence, or similar record. Upon reacquisition, the applicant may need to surrender or cancel immigration documents that treated the person as a foreign national. (Bureau of Immigration Philippines)
Applications filed at a field office may be transmitted to the BI’s RA 9225 unit or central office for final action. This can add processing time compared with a straightforward filing handled directly by the responsible central unit.
Fees and typical processing times
Published fees and processing periods can change. The final amount is the amount stated in the official Order of Payment Slip or the current consular schedule.
| Filing location | Published reference amount | Practical processing considerations |
|---|---|---|
| BI application in the Philippines | BI service page lists a total of ₱3,010 for the principal applicant | Document verification, central-office approval, and field-office transmittal may affect timing |
| Dependent child through a BI field-office process | A 2025 BI Davao charter lists ₱1,760 per dependent | Confirm the current amount with the receiving office |
| Philippine embassy or consulate | RA 9225 implementing rules provide a base fee of US$50 for the principal and US$25 per qualified minor beneficiary | Local currency conversion, mailing, certification, or administrative charges may apply |
The BI’s 2025 Davao Citizen’s Charter states an office-specific processing period of approximately 20 to 40 working days for a field-office application transmitted for final action. This should not be treated as a nationwide guarantee. A consular application may take several weeks when pre-evaluation, appointment availability, PSA verification, document authentication, or name discrepancies are involved.
The most frequent source of delay is usually not the oath itself. It is an incomplete or inconsistent civil-record trail.
Including minor children in the application
Under Section 4 of RA 9225, an unmarried child below 18 years old may derive Philippine citizenship from a parent who retains or reacquires citizenship. This can apply to a legitimate, illegitimate, or legally adopted child.
The parent should identify the child in the petition and submit the required supporting records, such as:
- The child’s birth certificate.
- The child’s foreign passport.
- Proof of the child’s foreign citizenship, where required.
- Adoption records for an adopted child.
- Documents proving the parent-child relationship.
- Recent photographs.
- The prescribed dependent form and fee.
A child who is already 18 or older cannot ordinarily obtain derivative citizenship as a minor beneficiary under Section 4. However, an adult child may already be a natural-born Philippine citizen if a parent was still Filipino when the child was born. That person should investigate a Report of Birth, passport, or recognition procedure rather than assume that an independent RA 9225 petition is required. (Supreme Court E-Library)
Does a foreign spouse become a Filipino citizen?
No. A foreign husband or wife does not automatically become a Philippine citizen when the former Filipino spouse reacquires citizenship.
The foreign spouse may consider:
- A Philippine immigrant visa based on marriage.
- Temporary resident status when applicable.
- Recognition of an existing immigrant status.
- Judicial or administrative naturalization, if legally qualified.
Marriage to a Filipino can create an immigration basis, but it is not automatic naturalization. The spouse must complete the applicable immigration or citizenship process.
Common problems that delay or derail applications
The name on the PSA record does not match the foreign passport
This frequently happens because of marriage, divorce, adoption, spelling changes, or the use of a middle name as part of a foreign surname.
Submit the official document that connects each name. An affidavit by itself may not be enough when a marriage certificate, court order, or civil-registry record should exist.
There is no PSA birth record
Check whether the birth was registered with the local civil registrar. If a local record exists but does not appear in the PSA database, it may need to be endorsed to the PSA.
When no civil-registry record exists, late registration may be necessary. This can significantly extend the application timeline because the applicant must establish the facts of birth through supporting records.
The applicant cannot find the old Philippine passport
An old passport is helpful but is not the only possible proof of former citizenship. Depending on the office, the applicant may submit a PSA birth certificate, parents’ records, voter records, school records, baptismal records, or other reliable evidence, together with an affidavit explaining the missing passport.
The foreign naturalization certificate is missing
Request a certified replacement or official citizenship record from the foreign government. A foreign passport normally proves present nationality but may not establish when or how the person acquired that citizenship.
The date and manner of acquisition matter because RA 9225 applies to loss of Philippine citizenship through foreign naturalization.
The applicant became a foreign citizen automatically
A person who acquired another nationality automatically at birth, by descent, or through operation of foreign law may not have lost Philippine citizenship in the first place. The correct procedure may be recognition, Report of Birth, or passport documentation—not reacquisition.
The applicant assumes dual citizenship rules are identical everywhere
Philippine law may allow the applicant to retain foreign citizenship, but the foreign country may have different rules. Confirm whether taking a Philippine oath, applying for a Philippine passport, voting, or holding public office affects the other citizenship.
The applicant travels before obtaining clear proof of status
For smoother departure and arrival processing, obtain a valid Philippine passport after approval. Until then, carry the original or certified copies of the order of approval, oath of allegiance, identification certificate, and current foreign passport, and verify the airline’s documentary requirements before travel. (Philippine Embassy in Berne)
What to do after the application is approved
Approval under RA 9225 is only the beginning of documenting and using the restored citizenship.
After approval:
Keep multiple certified copies of the approval documents. Replacement can be difficult, particularly when the oath was taken many years earlier or at a foreign post.
Apply for a Philippine passport. The passport is the most practical proof of Philippine citizenship for international travel.
Update Philippine immigration records. Surrender or cancel the ACR I-Card and related foreigner records when instructed by the BI.
Document children born abroad. File a Report of Birth when a child was born while the parent was a Philippine citizen and the birth has not yet been reported.
Register to vote when eligible. Citizenship approval does not automatically place the person on the voter list.
Review property and estate documents. A dual citizen buying or inheriting land should ensure that deeds, tax declarations, estate records, and citizenship documents consistently identify the owner.
Check licensing requirements before working in a regulated profession. Philippine citizenship does not replace Professional Regulation Commission registration, bar admission, or another agency’s licensing rules.
Review tax residency and income-source rules. RA 9225 does not create a separate tax regime. Philippine tax obligations depend on matters such as residence, source of income, business activity, property ownership, and applicable tax treaties. Dual citizenship alone does not produce the same tax result for every person. (Lawphil)
Frequently Asked Questions
Can I keep my US, Canadian, Australian, or other foreign citizenship?
Philippine law does not generally require a qualified RA 9225 applicant to renounce existing foreign citizenship. You must still check the law of the other country because its rules determine whether that citizenship is retained.
Do I need to live in the Philippines after reacquiring citizenship?
No general Philippine residence requirement is imposed merely to keep citizenship reacquired under RA 9225. Separate residence rules may apply when voting locally, running for office, obtaining benefits, or being treated as a Philippine tax resident.
Can a dual citizen own land in the Philippines?
Yes. A person who has validly reacquired Philippine citizenship generally has the landholding rights of a Philippine citizen. The purchase must still comply with property, marital-property, titling, agrarian, condominium, and land-use laws.
Can I apply even if I no longer have a Philippine passport?
Yes, provided you can prove that you were a natural-born Filipino. Expect to submit alternative citizenship evidence and an affidavit explaining why the passport is unavailable.
Can my 20-year-old child be included in my petition?
No, not as a derivative minor under Section 4 of RA 9225. Determine whether the child was already a Philippine citizen at birth because you were Filipino when the child was born. If so, a Report of Birth, recognition, or passport process may be appropriate.
Can I include my foreign spouse?
No. Derivative citizenship under RA 9225 applies to qualified unmarried children below 18, not to spouses. A foreign spouse must use the appropriate immigration or naturalization procedure.
Is a PSA birth certificate always required?
Most offices treat it as the primary evidence of Philippine birth and parentage. When no PSA record exists, the applicant may need local civil-registry endorsement, delayed registration, or additional evidence. Follow the checklist of the office processing the application.
Do I automatically receive a Philippine passport after taking the oath?
No. The passport requires a separate application, identity verification, biometrics, and payment. Some foreign posts allow the passport application to be filed on the same day as the oath, but approval under RA 9225 and issuance of a passport remain separate government actions.
Can I vote in Philippine elections after reacquiring citizenship?
You may register and vote if you meet the constitutional and statutory requirements, including the applicable domestic or overseas voting rules. Reacquisition does not automatically restore an old voter registration. (Supreme Court E-Library)
Does dual citizenship mean I must pay Philippine tax on all my worldwide income?
Not necessarily. Tax treatment depends on whether you are considered a resident or nonresident citizen, where the income is sourced, how long you stay in the Philippines, and whether a tax treaty applies. Citizenship is relevant, but it is not the only factor.
