Visão geral

Quem se qualifica
Evidence-pinned eligibility & rules:
- A person who becomes a citizen of Singapore by descent while a minor ceases to be a citizen on attaining the age of 22 UNLESS, within 12 months after attaining the age of 21, he takes the Oath of Renunciation, Allegiance and Loyalty (Second Schedule form) and, where the Government so requires, divests himself of any foreign citizenship or nationality. This is the descent-citizen retention/election obligation (Art 122(4)). [Art 122(4); ICA ask.gov.sg — oath at 21; DualCitizenshipReport — renounce by 22]
- Citizens of Singapore by BIRTH (jus soli) and by DESCENT are NOT subject to the deprivation grounds in Articles 129, 134 and 135, which the Constitution restricts to citizens by registration and/or by naturalisation. Birth and descent citizenship is consequently more secure against involuntary loss (the cease-at-22 election in Art 122(4)/126(3) being the principal exception for minor descent/registered citizens). [Art 129(1); Art 129(3)(b); Constitution Part X — residence-abroad deprivation]
- The Oath of Renunciation, Allegiance and Loyalty required by Articles 122(2), 126(1) and (3) and 127(4) is of no effect unless made in the prescribed form and signed in the presence of, or administered by, a Justice of the Peace or a person authorised to administer oaths (in Singapore), or a diplomatic or consular officer (if made elsewhere). [Singapore Citizenship Rules r.19(1)]

conditional
A person who became a citizen by descent as a minor CEASES to be a citizen on attaining age 22 UNLESS, within 12 months after attaining age 21, she takes the Oath of Renunciation, Allegiance and Loyalty (Second Schedule) and, where the Government so requires, divests herself of any foreign citizenship (Art 122(4); SG-E1-017/SG-E1-018). Isabella has until 15 June 2026 (12 months after turning 21) to take ORAL and renounce Italian citizenship if required. If she does so, she retains Singapore citizenship; if she does not, she loses it at age 22. Outcome is conditional on her timely election. This is the dual-citizen election-at-majority edge case.
ineligible
Under Art 122(4), a descent citizen who, within 12 months after attaining 21, fails to take the Oath of Renunciation, Allegiance and Loyalty (and divest foreign citizenship where required) ceases to be a citizen of Singapore on attaining age 22 (SG-E1-017). Marcus's 12-month window (20 May 2024 to 20 May 2025) elapsed with no ORAL taken; he ceased to be a Singapore citizen on his 22nd birthday (20 May 2025) by operation of law. This is the 'descent child not taking the oath at 21 -> cease at 22' edge case. He is not now a Singapore citizen (Japan citizenship preserves him from statelessness).
conditional
Rafael acquired descent citizenship validly as a minor (father a citizen by descent who met the Art 122(3) residence condition - 6 years > 5-year aggregate). The retention rule (Art 122(4); SG-E1-017/SG-E1-018) requires him, within 12 months after attaining 21 (i.e. by 30 September 2026), to take ORAL and, WHERE THE GOVERNMENT SO REQUIRES, divest himself of any foreign citizenship. Singapore does not permit adult dual citizenship as a general matter, so retention will in practice require renouncing Brazilian citizenship before/at ORAL. His stated intention to keep both nationalities conflicts with the divestment requirement. Outcome is conditional: if he takes ORAL and divests as required, he retains Singapore citizenship; if he refuses to divest, he cannot complete ORAL and will cease to be a citizen at 22. This is the dual-citizenship election tension at majority.
conditional
Even a SINGLE-nationality descent citizen must comply with the Art 122(4) retention mechanic: he ceases to be a citizen at age 22 unless, within 12 months after attaining 21, he takes the Oath of Renunciation, Allegiance and Loyalty (Second Schedule) (SG-E1-017). The divestment-of-foreign-citizenship limb only applies 'where the Government so requires' and is moot here because Sebastian has no foreign citizenship - but the OATH itself is still mandatory to retain citizenship. He has until 5 May 2026 to take ORAL. Outcome is conditional on him taking the oath; failure would, on a literal reading, cause cessation at 22 even though he is mono-national (a point on which administrative practice would be critical, but the constitutional text conditions retention on the oath). This edge case isolates the oath requirement from the divestment requirement.
