Filing for naturalization in the Philippines is not a simple immigration form. It is a citizenship process where the government checks not only your residence and documents, but also your character, income, integration into Filipino society, legal entry, school history, tax compliance, criminal record, and loyalty to the Philippines. For many applicants, the hard part is not one single document—it is proving, with complete and consistent evidence, that they strictly meet every requirement under Philippine law.
In the Philippines, a foreigner may generally become a Filipino citizen through judicial naturalization, administrative naturalization, or in rare cases, legislative naturalization. The correct path depends on your personal history: where you were born, how long you have lived in the Philippines, whether you studied here, your immigration status, your family situation, and whether you have any disqualification.
What Naturalization Means in the Philippines
Naturalization is the legal process by which a foreign citizen becomes a Filipino citizen.
The 1987 Philippine Constitution recognizes as Filipino citizens, among others, “those who are naturalized in accordance with law” under Article IV, Section 1(4). You can read the citizenship provisions in the 1987 Philippine Constitution, Article IV on Citizenship.
A naturalized Filipino becomes a Philippine citizen, but usually not a natural-born citizen. This distinction matters because some rights, public offices, and constitutional positions are reserved for natural-born Filipinos.
For example, a naturalized Filipino may generally enjoy ordinary rights of citizenship, such as the right to reside permanently in the Philippines and own land as a Filipino citizen. However, positions such as President, Vice President, Senator, Representative, and certain constitutional offices require natural-born citizenship.
Main Ways to Become a Naturalized Filipino Citizen
| Path | Who it is usually for | Where filed | Legal basis |
|---|---|---|---|
| Judicial naturalization | Most foreign adults who were not born and raised in the Philippines under RA 9139 | Regional Trial Court | Commonwealth Act No. 473, Revised Naturalization Law and Republic Act No. 530 |
| Administrative naturalization | Aliens born in the Philippines and residing here since birth, who meet RA 9139 requirements | Special Committee on Naturalization under the Office of the Solicitor General | Republic Act No. 9139, Administrative Naturalization Law of 2000 |
| Legislative naturalization | Exceptional cases where Congress passes a law granting citizenship to a specific person | Congress | Individual Republic Act |
| Re-acquisition or retention of citizenship | Former natural-born Filipinos who became foreign citizens | Bureau of Immigration or Philippine consulate, depending on location | Republic Act No. 9225, Citizenship Retention and Re-acquisition Act of 2003 |
A former Filipino who lost Philippine citizenship because of naturalization abroad usually does not file for ordinary naturalization. They normally use RA 9225, which is a different and simpler process for former natural-born Filipinos.
Judicial Naturalization Under Commonwealth Act No. 473
Judicial naturalization is the traditional court process under the Revised Naturalization Law. It is filed in court and is treated seriously because citizenship is considered a privilege granted by the State, not an automatic right.
The Supreme Court has repeatedly said that naturalization laws are strictly construed in favor of the government and against the applicant. In Republic v. Go Pei Hung, G.R. No. 212785, the Court emphasized that a petition must be denied when full and complete compliance with Commonwealth Act No. 473 is not shown. The decision is available through the Supreme Court E-Library.
Basic Qualifications for Judicial Naturalization
Under Section 2 of Commonwealth Act No. 473, an applicant must generally prove that they:
- Are at least 21 years old on the day of the hearing;
- Have resided in the Philippines for a continuous period of at least 10 years;
- Are of good moral character;
- Believe in the principles underlying the Philippine Constitution;
- Have conducted themselves in a proper and irreproachable manner during their residence in the Philippines;
- Own real estate in the Philippines worth at least ₱5,000, or have a known lucrative trade, profession, or lawful occupation;
- Can speak and write English or Spanish and one principal Philippine language; and
- Have enrolled their minor children of school age in Philippine schools where Philippine history, government, and civics are taught.
The ₱5,000 property amount is an old statutory figure, but in practice, courts focus heavily on whether the applicant has a stable and lawful source of income, pays taxes properly, and will not become a public charge.
When the 10-Year Residence Requirement Is Reduced to 5 Years
Under Section 3 of Commonwealth Act No. 473, the usual 10-year residence requirement may be reduced to 5 years if the applicant falls under certain categories, such as:
- Having honorably held office under the Philippine government;
- Having established a new industry or introduced a useful invention in the Philippines;
- Being married to a Filipino spouse;
- Having taught in the Philippines for at least 2 years in a public or recognized private school not limited to a particular nationality or race; or
- Having been born in the Philippines.
In real life, many foreign spouses of Filipinos ask whether marriage automatically gives them Philippine citizenship. It does not. Marriage may help shorten the residence requirement in the proper case, but the foreign spouse still has to go through naturalization and prove all legal requirements.
Disqualifications for Judicial Naturalization
Even if a person meets the basic qualifications, they cannot be naturalized if they fall under the disqualifications in Section 4 of Commonwealth Act No. 473. These include:
- Being opposed to organized government;
- Advocating violence, personal assault, or assassination for political or ideological success;
- Being a polygamist or believer in polygamy;
- Having been convicted of a crime involving moral turpitude;
- Suffering from mental alienation or incurable contagious disease;
- Not having mingled socially with Filipinos or not showing sincere desire to embrace Filipino customs, traditions, and ideals;
- Being a citizen or subject of a country at war with the Philippines; or
- Being a citizen of a country whose laws do not allow Filipinos to become naturalized citizens there.
That last point is the reciprocity requirement. If the applicant’s country does not allow Filipinos to naturalize there, the applicant may be disqualified from Philippine naturalization.
Step-by-Step Process for Judicial Naturalization
1. Confirm that you are eligible before filing anything
Before preparing a petition, the applicant should first check:
- Length of continuous residence in the Philippines;
- Immigration status and proof of lawful entry;
- Tax records;
- Employment, business, or professional income;
- Criminal, court, barangay, and immigration records;
- School records of minor children;
- Language ability;
- Country reciprocity;
- Any possible disqualification.
This early screening is important because one missing jurisdictional requirement can cause dismissal even after years of litigation.
2. File a Declaration of Intention, if required
Under Section 5 of Commonwealth Act No. 473, an applicant must generally file a Declaration of Intention one year before filing the naturalization petition.
The declaration states that the applicant truly intends to become a Filipino citizen. It includes personal details such as name, age, occupation, place of birth, former residence, allegiance, date of arrival, vessel or aircraft used, and present Philippine residence.
This requirement is not a formality. In Sefyan Abdelhakim Mohamed v. Republic, G.R. No. 220674, the Supreme Court upheld the strict treatment of the declaration requirement and cancellation consequences where compliance was defective. The case may be read in the Supreme Court E-Library decision on Mohamed v. Republic.
Some applicants may be exempt from filing a Declaration of Intention, such as those who were born in the Philippines and received primary and secondary education in Philippine schools recognized by the government and not limited to a particular nationality or race. However, exemptions should be examined carefully because courts require clear proof.
3. Prepare the Petition for Naturalization
Under Section 7 of Commonwealth Act No. 473, the petition must be filed in triplicate and must contain detailed information, including:
- Full name and surname;
- Present and former residences;
- Occupation;
- Place and date of birth;
- Civil status;
- Details of spouse and children;
- Approximate date of arrival in the Philippines;
- Port of entry;
- Vessel or aircraft used, if remembered;
- Statement that the applicant has all qualifications and none of the disqualifications;
- Statement that the applicant complied with the Declaration of Intention requirement, if applicable; and
- Statement that the applicant will reside continuously in the Philippines from filing until admission to citizenship.
The petition must be signed by the applicant in their own handwriting.
4. Secure two credible Filipino witnesses
The petition must be supported by the affidavit of at least two credible Filipino citizens who personally know the applicant.
These witnesses must be more than casual acquaintances. They should be able to credibly testify that the applicant:
- Has resided in the Philippines for the required period;
- Is of good repute;
- Is morally irreproachable;
- Has the qualifications for citizenship; and
- Is not disqualified under the law.
In Ho Ching Yi v. Republic, G.R. No. 227600, the Supreme Court stressed that “credible persons” must have good standing in the community and must genuinely vouch for the applicant’s worthiness. The decision is available in the Supreme Court E-Library case of Ho Ching Yi v. Republic.
5. Attach required documents
Common documents in judicial naturalization include:
| Document | Practical purpose |
|---|---|
| Certificate of Arrival or equivalent Bureau of Immigration record | Proves lawful entry into the Philippines |
| ACR I-Card and immigration records | Shows legal immigration status |
| Passport pages and visas | Supports travel and residence history |
| Birth certificate | Proves identity and place of birth |
| Marriage certificate, if married | Proves civil status and spouse details |
| Birth certificates of children | Required if applicant has children |
| School certifications for minor children | Proves compliance with Philippine schooling requirement |
| Income tax returns and BIR records | Shows tax compliance and lawful income |
| Employment certificate, business permits, SEC/DTI records, or professional documents | Shows lawful occupation or business |
| NBI, police, barangay, court, and prosecutor clearances | Helps prove good moral character and absence of derogatory records |
| Affidavits of witnesses | Supports character, residence, and integration |
| Proof of language ability and integration | Supports ability to speak/write required languages and mingle with Filipinos |
A major practical issue is consistency. Names, dates, addresses, immigration entries, school records, and tax filings should match across documents. In naturalization cases, inconsistencies are often treated seriously.
6. File in the proper Regional Trial Court
Commonwealth Act No. 473 originally refers to the Court of First Instance. Today, this jurisdiction is exercised by the Regional Trial Court (RTC).
The petition is filed in the RTC of the province or city where the applicant has resided for at least one year immediately before filing.
7. Publication and notice requirements
After filing, the petition must be published at the applicant’s expense.
Under Section 9 of Commonwealth Act No. 473, the notice must be published once a week for three consecutive weeks and the hearing cannot be held too soon after publication. Republic Act No. 530 also provides that no petition for Philippine citizenship shall be heard by the courts until after six months from publication.
This publication requirement gives the government and the public an opportunity to oppose the petition if there are valid grounds.
8. Court hearing and government opposition
Naturalization hearings are public. The Office of the Solicitor General, or its deputized representative, appears for the Republic.
At the hearing, the applicant and witnesses may be questioned about:
- Residence history;
- Immigration status;
- Family background;
- Work, business, or profession;
- Tax compliance;
- Moral character;
- Community involvement;
- Language ability;
- Knowledge of Philippine government, history, and civic duties;
- Travel outside the Philippines;
- Possible disqualifications; and
- Whether the applicant truly intends to become Filipino.
The government may oppose the petition if there are missing documents, insufficient proof, inconsistent statements, unpaid taxes, criminal issues, questionable witnesses, or failure to strictly comply with the law.
9. Court decision and two-year waiting period
If the RTC grants the petition, the applicant does not automatically become a Filipino citizen on that date.
Republic Act No. 530 provides that a decision granting naturalization does not become executory until after two years from promulgation and after the court is satisfied, at a proper hearing with the Solicitor General or representative present, that during the intervening period the applicant:
- Did not leave the Philippines;
- Dedicated themselves continuously to a lawful calling or profession;
- Was not convicted of any offense or violation of government rules; and
- Did not commit any act prejudicial to national interest or contrary to government policies.
This two-year period is a common bottleneck. Travel abroad during this period can create serious problems. In naturalization practice, the safest assumption is that the applicant must remain in the Philippines unless the court and applicable jurisprudence clearly allow otherwise.
10. Oath of allegiance and certificate of naturalization
Only after the required findings are made may the applicant take the oath of allegiance and receive the certificate of naturalization.
The oath is important because citizenship is completed only upon compliance with the final legal steps. Before the oath and issuance of the proper certificate, the applicant should not assume that they already enjoy all rights of a Filipino citizen.
Administrative Naturalization Under Republic Act No. 9139
Administrative naturalization is a separate process under RA 9139, also known as the Administrative Naturalization Law of 2000. It is not for every foreigner.
It is mainly for aliens who were born in the Philippines and have resided in the Philippines since birth, and who satisfy the specific requirements of the law.
Applications are handled by the Special Committee on Naturalization (SCN), composed of the Solicitor General as Chair, the Secretary of Foreign Affairs or representative, and the National Security Adviser. The Office of the Solicitor General has an official page for the Special Committee on Naturalization.
Who May Apply for Administrative Naturalization
Under Section 3 of RA 9139, the applicant must generally prove that they:
- Were born in the Philippines and have resided here since birth;
- Are at least 18 years old at the time of filing;
- Are of good moral character;
- Believe in the principles underlying the Philippine Constitution;
- Have conducted themselves properly and irreproachably with the government and community;
- Received primary and secondary education in a Philippine public school or recognized private school where Philippine history, government, and civics are taught and enrollment is not limited by race or nationality;
- Have a known trade, business, profession, or lawful occupation sufficient for support, unless exempt under the law;
- Can read, write, and speak Filipino or any Philippine dialect; and
- Have mingled with Filipinos and sincerely desire to embrace Filipino customs, traditions, and ideals.
Disqualifications Under RA 9139
RA 9139 disqualifies applicants who are:
- Opposed to organized government;
- Advocates of violence, personal assault, or assassination for the success of their ideas;
- Polygamists or believers in polygamy;
- Convicted of crimes involving moral turpitude;
- Suffering from mental alienation or incurable contagious disease;
- Not socially integrated with Filipinos;
- Citizens or subjects of a country at war with the Philippines; or
- Citizens of a country whose laws do not grant Filipinos the right to become naturalized citizens there.
Documents Commonly Required for Administrative Naturalization
The SCN requires strict and organized compliance. Based on the OSG’s published requirements, regular petitioners should expect to prepare documents such as:
| Requirement | Notes |
|---|---|
| PSA birth certificate | Must be authenticated or PSA-issued |
| ACR I-Card certificate | Issued by the Bureau of Immigration |
| Native-Born Certificate of Residence, if available | Also from the Bureau of Immigration |
| PSA marriage certificate, if married | Include spouse details |
| Court decree of annulment, nullity, or legal separation, if applicable | Certified true copy |
| PSA birth certificates of children | Required if applicant has children |
| NBCR or immigration records of children, if applicable | From BI |
| Affidavit of financial capacity | May include bank certifications, employment records, business documents, property documents, and proof of assets |
| ITRs and tax documents for the past 3 years | Must show BIR filing/payment proof |
| Affidavits of at least 2 credible Filipino witnesses | Witnesses should have known the applicant for at least 10 years |
| NBI clearance of character witnesses | Required by SCN guidance |
| Medical certificate from a government hospital | Includes neuro-psychiatric evaluation, drug test, HIV test, and other required lab results |
| School diplomas and transcripts | Elementary, high school, and college records in the Philippines |
| School records of minor children | Must show enrollment in schools teaching Philippine history, government, and civics |
| Clearances | NBI, barangay, police, RTC, MeTC/MTCC/MTC/MCTC, and prosecutor clearances |
The SCN warns that strict compliance, not substantial compliance, is required. It also states that false or falsified documents may result in denial and possible criminal prosecution.
Fees for Administrative Naturalization
Based on the OSG’s published SCN information, the fees for regular petitioners are:
| Fee | Amount |
|---|---|
| Application form fee | ₱1,000 |
| Filing and docketing fee | ₱39,000 |
| Oath-taking and naturalization fee | ₱100,000 |
| Total | ₱140,000 |
There are also publication fees, payable directly to the assigned accredited newspaper, and expenses for securing government documents and clearances.
Administrative Naturalization Process
The OSG describes the administrative naturalization process as involving several stages. In practical terms, it usually looks like this:
- Secure and fill out the petition/application form.
- Prepare the documentary requirements in an organized file with a table of contents.
- Submit the petition for pre-evaluation.
- Personally file the petition; the applicant must be present because a photo will be taken.
- The petition is assigned by raffle to a Naturalization Review Officer, an OSG lawyer.
- The NRO evaluates the petition and may require additional documents.
- Once documents are compliant, copies are transmitted to government agencies for posting, background checks, and reports.
- The petition is raffled to an accredited newspaper for publication once a week for three consecutive weeks.
- The applicant waits for agency reports and the affidavit of publication.
- The NRO evaluates all reports received.
- The applicant and character witnesses may be scheduled for written examination and interview.
- The NRO prepares an evaluation report for the SCN.
- The SCN deliberates.
- If approved, the applicant attends oath-taking.
- The applicant’s ACR I-Card is cancelled with the Bureau of Immigration.
Administrative naturalization is often document-heavy. Delays commonly happen when clearances expire, school records are incomplete, tax documents are unclear, witness affidavits are weak, or the SCN requests additional proof.
Judicial vs. Administrative Naturalization
| Issue | Judicial naturalization | Administrative naturalization |
|---|---|---|
| Main applicant type | Foreigners who meet CA 473 requirements | Aliens born in the Philippines and residing here since birth |
| Minimum age | 21 at hearing | 18 at filing |
| Main office | RTC | Special Committee on Naturalization |
| Residence requirement | Usually 10 years, reducible to 5 years in certain cases | Born and residing in the Philippines since birth |
| Publication | Required | Required |
| Character witnesses | At least 2 credible Filipino witnesses | At least 2 credible Filipino witnesses, with stricter SCN documentary expectations |
| Government participation | OSG or representative appears in court | SCN/OSG directly evaluates |
| Waiting period after approval | RA 530 two-year period applies to judicial naturalization | RA 9139 has its own approval, fee, oath, certificate, and BI cancellation process |
| Common bottleneck | Strict court compliance and two-year period | Document completeness, background checks, exam/interview, additional SCN requirements |
Common Reasons Naturalization Petitions Are Denied
Missing or defective Certificate of Arrival
The Certificate of Arrival or equivalent proof of lawful entry is crucial in judicial naturalization. In Republic v. Go Pei Hung, the Supreme Court held that failure to attach the required Certificate of Arrival was fatal because the State must be able to determine that the applicant entered the Philippines lawfully.
Permanent residence alone does not automatically cure a missing proof of lawful entry.
Weak or unqualified character witnesses
Witnesses must be credible in the legal sense. They should not merely say, “I know the applicant is a good person.” They must be able to explain how long they have known the applicant, how they know the applicant’s character, and why they can vouch for the applicant’s qualifications.
Inconsistent names, dates, or addresses
Naturalization applications often fail or get delayed because of mismatched details, such as:
- Different spellings of names;
- Inconsistent birth dates;
- Undeclared former names;
- Unexplained address gaps;
- Conflicting immigration entries;
- Different civil status information across records; or
- Undeclared children or prior marriages.
If there are legitimate discrepancies, they should be explained and supported with proper documents.
Tax problems
Income tax returns are not just financial documents. They show lawful income, compliance with Philippine law, and seriousness as a future citizen.
Common issues include:
- No ITR despite employment or business;
- ITRs that do not match claimed income;
- Business income without proper registration;
- Unpaid tax liabilities;
- Late filings without explanation; or
- Dependence on undocumented support.
Leaving the Philippines during the RA 530 period
For judicial naturalization, the two-year period after a favorable decision is critical. RA 530 requires the court to find that the applicant did not leave the Philippines during the intervening period, among other conditions.
Applicants who travel after winning the case but before oath-taking may place the entire petition at risk.
Assuming marriage gives automatic citizenship
A foreign spouse of a Filipino does not automatically become Filipino by marriage. The foreign spouse may qualify for immigration benefits, such as a 13(a) visa in proper cases, but citizenship still requires naturalization unless another specific law applies.
Confusing RA 9225 with naturalization
RA 9225 is for former natural-born Filipinos who became foreign citizens. It is not the same as naturalization for foreigners who were never Filipino.
A foreign husband, wife, or child of a former Filipino does not automatically become a Filipino citizen under RA 9225 except where the law grants derivative citizenship to qualified minor children.
Practical Timeline
Timelines vary widely depending on the completeness of documents, court calendars, publication, government reports, opposition by the Republic, and additional requirements.
| Process | Practical timeline |
|---|---|
| Preparing documents | 2 to 6 months, sometimes longer if records are missing |
| Declaration of Intention | Must generally be filed 1 year before judicial petition, unless exempt |
| Judicial naturalization case | Often several years depending on court proceedings and opposition |
| RA 530 waiting period after favorable judicial decision | 2 years before decision becomes executory, subject to required findings |
| Administrative naturalization | Often many months to several years depending on SCN evaluation, publication, reports, exam/interview, and additional requirements |
For both judicial and administrative naturalization, applicants should expect the process to be measured in years, not weeks.
What Happens After Approval
After the oath and issuance of the proper certificate, the new Filipino citizen should update records with relevant agencies.
Common post-naturalization steps include:
- Registration of the naturalization certificate with the local civil registrar, when applicable;
- Cancellation of ACR I-Card with the Bureau of Immigration;
- Updating civil registry records;
- Applying for Philippine identification documents;
- Applying for a Philippine passport through the DFA;
- Updating tax, employment, business, bank, school, and property records as needed.
A newly naturalized Filipino should keep certified copies of the decision, oath, certificate of naturalization, and civil registry records. These documents may be requested later for passport applications, property transactions, banking, employment, or correction of records.
Effect on Spouse and Children
The effect of naturalization on family members depends on the legal route and the family member’s status.
Under Commonwealth Act No. 473, minor children may acquire citizenship in certain situations depending on birth, residence, and timing. Under RA 9139, the law separately discusses the status of the alien wife, husband, and minor children, and the SCN process may require petitions for cancellation of alien certificates of registration and payment of corresponding fees.
This is an area where the facts matter. Important details include:
- Whether the child is legitimate, illegitimate, or adopted;
- The child’s age;
- Whether the child is residing in the Philippines;
- Whether the child was born before or after the parent’s naturalization;
- Whether the child has an ACR I-Card;
- Whether the child is enrolled in a qualifying Philippine school; and
- Whether the spouse independently qualifies.
A spouse should not assume that the applicant’s naturalization automatically covers them.
Dual Citizenship Issues After Philippine Naturalization
Philippine naturalization requires an oath of allegiance to the Philippines and, under the wording of the naturalization laws, a renunciation of foreign allegiance.
However, whether the applicant will lose their original citizenship depends also on the law of their country of origin. Some countries automatically revoke citizenship upon foreign naturalization; others allow dual citizenship; others require a separate renunciation procedure.
Before filing, the applicant should check the nationality law of their current country because the Philippine process may have consequences for their passport, property, inheritance, taxation, military obligations, and immigration status abroad.
Frequently Asked Questions
Can a foreigner become a Filipino citizen?
Yes. A foreigner may become a Filipino citizen if they qualify under Philippine naturalization laws. The most common route is judicial naturalization under Commonwealth Act No. 473. Aliens born in the Philippines and residing here since birth may qualify for administrative naturalization under RA 9139.
How many years must a foreigner live in the Philippines before applying for citizenship?
For judicial naturalization, the general rule is continuous residence for at least 10 years. This may be reduced to 5 years in certain cases, such as being born in the Philippines, being married to a Filipino spouse, teaching in a qualifying Philippine school, holding certain government office, or establishing a new industry or useful invention.
Does marrying a Filipino automatically make me a Filipino citizen?
No. Marriage to a Filipino does not automatically grant Philippine citizenship. It may help reduce the residence requirement in a proper judicial naturalization case, but the foreign spouse must still prove all qualifications and none of the disqualifications.
Where do I file for naturalization in the Philippines?
For judicial naturalization, the petition is filed in the Regional Trial Court of the place where the applicant has resided for at least one year immediately before filing. For administrative naturalization under RA 9139, the petition is filed with the Special Committee on Naturalization under the Office of the Solicitor General.
How much does administrative naturalization cost?
Based on the OSG’s published SCN schedule, regular administrative naturalization fees total ₱140,000, consisting of a ₱1,000 application form fee, ₱39,000 filing and docketing fee, and ₱100,000 oath-taking and naturalization fee. Publication fees and document-related expenses are separate.
Is there a citizenship exam in the Philippines?
For administrative naturalization, the SCN process includes a written exam and interview for the applicant, and interviews of character witnesses. In judicial naturalization, the applicant and witnesses are examined in court, and questions may cover qualifications, residence, work, language ability, moral character, and integration into Filipino society.
Can I apply for Philippine citizenship if I was not born in the Philippines?
Yes, but usually through judicial naturalization under Commonwealth Act No. 473, not administrative naturalization under RA 9139. Administrative naturalization is generally for those born in the Philippines and residing here since birth.
Can a naturalized Filipino own land in the Philippines?
A naturalized Filipino is a Philippine citizen and may generally own land, subject to ordinary legal rules. Before naturalization, a foreigner is generally restricted by Article XII, Section 7 of the Constitution, which limits private land ownership to those qualified to acquire or hold lands of the public domain, except in cases such as hereditary succession.
Can my application be denied even if I have lived in the Philippines for many years?
Yes. Long residence alone is not enough. The applicant must strictly prove all qualifications, no disqualifications, lawful entry, good moral character, proper income, tax compliance, language ability, integration with Filipinos, proper schooling of minor children, and complete procedural compliance.
Is RA 9225 the same as naturalization?
No. RA 9225 is for former natural-born Filipinos who lost Philippine citizenship because they became citizens of another country. It allows them to retain or re-acquire Philippine citizenship by taking the required oath. It is not the ordinary naturalization process for foreigners who were never Filipino citizens.
