Сохранение гражданства и повторное приобретение гражданства по рождению (RA 9225)

RA 9225, short-titled the "Citizenship Retention and Re-acquisition Act of 2003," is the principal modern mechanism by which natural-born Filipinos who have acquired a foreign nationality recover or preserve their Philippine citizenship. The Act's full title is "AN ACT MAKING THE CITIZENSHIP OF PHILIPPINE CITIZENS WHO ACQUIRE FOREIGN CITIZENSHIP PERMANENT, AMENDING FOR THE PURPOSE COMMONWEALTH ACT NO. 63, AS AMENDED, AND FOR OTHER PURPOSES." Its legal character is dual: it operates restoratively for natural-born Filipinos who lost citizenship by foreign naturalization before the Act took effect (these "re-acquire"), and preservatively for those who become foreign citizens after effectivity (these "retain"). As of 2026 it is the operative route and the single most-used pathway for the Filipino diaspora to regain full Philippine citizenship.

The doctrinal centerpiece, settled by David v. Agbay (2015), is that the heading of §3 ("Retention of Philippine Citizenship") is not the whole story: "the authors of the law intentionally employed the terms 're-acquire' and 'retain' to describe the legal effect of taking the oath of allegiance to the Republic of the Philippines." The mechanism in both cases is a single, simple act — taking the prescribed oath of allegiance — yet the characterisation differs by whether foreign naturalisation occurred before or after the Act's effectivity. RA 9225 thus tolerates dual citizenship for natural-born Filipinos, expressly reversing the CA 63 rule that foreign naturalisation extinguished Philippine citizenship. It is not a naturalisation route and confers no citizenship on aliens; it restores or preserves a status the beneficiary already held by birth.

1. Re-acquirers (first paragraph of §3): natural-born Filipinos who lost Philippine citizenship by naturalisation in a foreign country before RA 9225's effectivity. These are "deemed to have reacquired Philippine citizenship upon taking the … oath of allegiance." Per David, "R.A. 9225 itself treats those of his category as having already lost Philippine citizenship."
2. Retainers (second paragraph of §3): natural-born Filipinos who, after effectivity, become foreign citizens. These "shall retain their Philippine citizenship upon taking the aforesaid oath." Their Philippine citizenship is never extinguished; the oath is confirmatory.

Persons who became Filipino only by naturalisation (CA 473 judicial, RA 9139 administrative, or legislative act) are outside RA 9225 — Bengson III v. HRET establishes there are "only two classes of citizens, i.e., natural-born and naturalized," and RA 9225 is reserved to the former. Aliens who were never Filipino cannot use the Act. Foundlings, held natural-born in Poe-Llamanzares (2016), are eligible: "Because a foundling is natural-born," a foundling who later acquires foreign citizenship may retain/re-acquire under RA 9225.

The decoded primary corpus fixes the legal predicates but not the granular administrative checklist (the BI sub-pages returned 403/404 this cascade; the documentary list is, scheduled post-ingest). What the primary record establishes:

• Proof of natural-born status is the gating document set — typically a PSA birth certificate and supporting parental citizenship evidence — because RA 9225 is reserved to natural-born Filipinos (David: §3 conditions apply "for two categories of natural-born Filipinos").
• Proof of foreign naturalisation (the foreign certificate of naturalisation/passport) establishes which paragraph of §3 applies; in David the petitioner "migrated to Canada where he became a Canadian citizen by naturalization."
• The executed §3 oath of allegiance before an authorised officer is the operative instrument.
• The Identification Certificate (IC) is the evidentiary output — David references "Identification Certificate No. 266-10-07 issued by the Consulate General of the Philippines (Toronto)."

For those who intend to exercise reacquired rights, additional evidentiary acts attach: a separate personal and sworn renunciation of foreign citizenship for elective-office aspirants (§5(2)), and registration for overseas voting under RA 9189 (§5(1)). These are downstream of, and distinct from, the reacquisition itself.

RA 9225 (re-)acquisition is processed through two parallel channels, both culminating in the §3 oath and the issuance of an Identification Certificate (IC):

• Domestic channel — Bureau of Immigration (BI): an applicant in the Philippines petitions the BI, which adjudicates natural-born status and administers the oath. David v. Agbay records the BI's role: the petitioner "cites the letter-reply dated January 31, 2011 of the Bureau of Immigration (BI) to his query, stating that his status as a natural-born Filipino will be governed by Section 2 of R.A. 9225."
• Overseas channel — Philippine Foreign Service Post (DFA consulate/embassy): an applicant abroad files with the consular post, which administers the oath and issues the IC. David documents exactly this: the petitioner "re-acquired his Filipino citizenship under the provisions of Republic Act No. 9225 … as evidenced by Identification Certificate No. 266-10-07 issued by the Consulate General of the Philippines (Toronto) on October 11, 2007."

The operative legal act is the oath: the statute deems citizenship reacquired/retained "upon taking the … oath of allegiance to the Republic." Administrative formalities (petition forms, IC issuance) evidence the oath rather than constitute the grant. Japzon v. COMELEC confirms the standard sequence in practice — the beneficiary takes the oath before a consular officer and may then obtain a Philippine passport: "Ty complied with the requirements of Sections 3 and 5 of Republic Act No. 9225 and reacquired his Philippine citizenship." Current BI/DFA fee schedules are set by administrative circulars (access-blocked, scheduled post-ingest); the statute fixes no fee for RA 9225.

RA 9225 reacquisition is, by design, a fast mechanism relative to naturalisation. Bengson III contrasts repatriation/reacquisition with "the lengthy process of naturalization," noting reacquisition "simply consists of the taking of an oath of allegiance … and registering said oath." The operative legal effect is instantaneous upon the oath; no probationary period (unlike the two-year wait under CA 473 naturalisation) applies.

On retroactivity, the apex law distinguishes the date of legal effect from the date of the act. David v. Agbay notes that Frivaldo v. COMELEC (G.R. No. 120295, 1996) and Altarejos v. COMELEC (G.R. No. 163256, 2004) recognise "the retroactivity of one's re-acquisition of Philippine citizenship to the date of filing his application therefor" — a doctrine that can validate qualifications for office retroactively. However, David holds this retroactivity does not cure an antecedent misrepresentation: for a first-paragraph re-acquirer, "the falsification was already a consummated act, the said law having no retroactive effect insofar as his dual citizenship status is concerned." Thus reacquisition is prompt and, for office-eligibility purposes, may relate back, but it does not rewrite the applicant's status at moments before the oath for purposes such as land ownership or criminal liability. The Act's own effectivity (fifteen days after publication, §8) is the temporal pivot dividing "re-acquire" from "retain."

RA 9225 §3 (Retention/Re-acquisition), first paragraph: "natural-born citizens of the Philippines who have lost their Philippine citizenship by reason of their naturalization as citizens of a foreign country are hereby deemed to have reacquired Philippine citizenship upon taking the following oath of allegiance to the Republic." Second paragraph: "Natural-born citizens of the Philippines who, after the effectivity of this Act, become citizens of a foreign country shall retain their Philippine citizenship upon taking the aforesaid oath."

The §3 oath of allegiance: "I ______, solemnly swear (or affirm) that I will support and defend the Constitution of the Republic of the Philippines and obey the laws and legal orders promulgated by the duly constituted authorities of the Philippines; and I hereby declare that I recognize and accept the supreme authority of the Philippines and will maintain true faith and allegiance thereto; and that I impose this obligation upon myself voluntarily without mental reservation or purpose of evasion."

RA 9225 §8 (Effectivity): "This Act shall take effect after fifteen (15) days following its publication in the Official Gazette or two (2) newspaper[s] of general circulation."

Constitutional anchor — 1987 Constitution Art. IV §3: "Philippine citizenship may be lost or reacquired in the manner provided by law." Art. IV §2 defines natural-born citizens as "those who are citizens of the Philippines from birth without having to perform any act to acquire or perfect their Philippine citizenship." Art. IV §5 ("Dual allegiance of citizens is inimical to the national interest and shall be dealt with by law") is the provision against which RA 9225 was challenged and upheld.
