I hope this settles the issue once and for all. Only minors below the age of 21 are
temporarily given the option of holding on to multiple citizenship until age 21 when they are legally required to hold only one by providing proof of renunciation of all remaining foreign citizenship to ICA. As far as the
Singapore Constitution goes; the Singapore govt can and will strip any Singaporean of his citizenship if he holds foreign citizenship or exercise the rights of a foreign citizen.

the case for dual citizenship
Is Singapore ready for dual citizenship? In a reply to a reader’s letter to The Straits Times forum, the Immigration & Checkpoints Authority’s (ICA) response was, “We have yet to reach the stage of nationhood where a Singaporean with a second citizenship would still retain his identity and loyalty to Singapore as his homeland wherever he goes, with his second citizenship being only of secondary importance.” This caused quite a stir, prompting responses from the public in favour of Mr Betrand Teo, the author of the letter. Ms Mabel Leong asked ICA for evidence of its claim, otherwise, to her, “The statement is, at best, academic and unproven and, in my view, outdated.”
Ms Leong referred to the recent trend of globalisation and the changing demographic pattern of the population, “Because globalisation results in freer movement across borders, the ICA, and government agencies should look critically into whether a dual-citizenship policy would promote a freer flow of human capital into Singapore.” Another reader wrote in and summed up the debate with this analogy, “Most people have two parents. Do we feel less loyal to any one of our parents? I doubt so, in the average family setting.”
Deprivation of citizenship
(The Singapore Constitution).
A person may lose his/her Singapore citizenship in the following cases:
a.in the case of a minor citizen, if he/she failed to take the Oath of Renunciation, Allegiance & Loyalty within 1 year of turning 21;
b.Where the person, while 18 years or older, acquired the citizenship of another country;
c.Where the person renounced his/her citizenship.
The government may, by order, deprive a person of his/her citizenship, if it is satisfied that the person: -
a.had, (when 18 years or older) voluntarily claimed and exercised rights accorded exclusively to citizens or nationals of foreign countries, such as the right to vote; or
b.had, (when 18 years old or older) applied for or used a foreign passport; or
c.is 18 years or older and has failed to return to Singapore over a continuous period of 10 years, including any period before 2 January 1986.

Dual citizenship is generally not recognised in Singapore[6], but is possible under certain circumstances. Singaporean citizens who acquire citizenship of a foreign country after the age of 18 may lose Singaporean citizenship[5]. Foreigners who naturalise as Singaporean citizens are required to renounce all foreign citizenships. Minors who are dual or multiple citizens by birth on foreign soil, by descent from foreign parents or by naturalisation before the age of 18 are required to renounce all foreign citizenships by the age of 22 or may lose their Singaporean citizenship[5].
The prohibition of dual citizenship is a contentious issue in Singapore. As the economy has become more global and Singaporeans have become more mobile, many Singaporeans have acquired foreign citizenships and reluctantly renounced their Singaporean citizenship even though they may feel a strong emotional attachment to Singapore. Immigrants who have been resident in Singapore for long periods and qualify for Singaporean citizenship may be reluctant to become naturalized citizens as it would mean giving up the citizenship of their native countries. Those who are dual citizens at birth may find it unjust that they are denied their birthright to citizenship of other countries where they were born or that of their parents. Male dual citizens are also not allowed to renounce Singaporean citizenship after the age of 11 and before attaining majority at the age of 21, such that they have to serve National Service at the age of 18 for a country to whom allegiance they may almost immediately abjure.[7]
The government's rationale for not allowing dual citizenship is that Singapore is a young and vulnerable nation which cannot afford to allow its citizens multiple allegiances which may be compromised in times of national crisis. Citizens without a second citizenship may feel aggrieved if dual citizens enjoy the benefits of citizenship during periods of wealth but leave the country in trying times.[8].
Nevertheless, the government is open to the possibility of allowing dual citizenship if local and global circumstances demand so.[9]
