Singapore citizenship and oath ceremony — Costs and fees breakdown

Singapore citizenship and the oath ceremony are the final steps in a residence journey: eligible permanent residents apply through ICA, renounce foreign citizenship where required, and take the Oath of Renunciation, Allegiance and Loyalty at a ceremony. This guide breaks down eligibility, documents, timelines, costs and pitfalls for 2026.

What Singapore citizenship involves

Singapore citizenship confers full civic status, including the right to a Singapore passport, the right to vote, and access to the widest range of housing and other benefits. It is granted at the discretion of the Government under the Constitution of the Republic of Singapore and the relevant citizenship provisions, and it is the natural endpoint for permanent residents who intend to make Singapore their permanent home.

Singapore does not recognise dual citizenship for adults. A successful applicant who holds another nationality is generally required to renounce it, and the final grant is conditional on completing that renunciation and taking the citizenship oath.

Who is eligible

An adult applicant generally must have been a permanent resident for at least two years and be at least 21 years old, though ICA assesses each case on its merits, weighing the applicant’s ties, contribution and intention to settle. Spouses of citizens, and children of citizens, have separate eligibility routes with their own criteria.

As with permanent residence, eligibility to apply does not guarantee approval. The citizenship assessment builds on the PR track record, so the succession planning across PR and citizenship perspective and, for entrepreneurs, Pte Ltd registration for foreigners are useful context for how business and family ties strengthen a case. Our analysis of PR approval odds by salary band also illuminates how economic contribution is weighed at each stage.

Documents and the application process

Applications are submitted online through ICA’s e-Service. Required documents typically include the applicant’s identity card and passport, birth and marriage certificates, educational and professional qualifications, employment and income records, and documents for any children included. Non-English documents require official translation.

After submission, ICA reviews the application and may request additional information or an interview. Because citizenship is a significant and largely irreversible step, applicants should ensure their file is complete and their intention to reside permanently is clearly evidenced.

The oath ceremony, costs and timeline

On approval-in-principle, an applicant who holds another citizenship completes renunciation, then attends a citizenship ceremony to take the Oath of Renunciation, Allegiance and Loyalty, after which the Singapore citizenship certificate and identity card are issued and the pink identity card and passport can be obtained. The ceremony is a formal civic event, often organised at community level.

Government fees are modest: the citizenship application fee and subsequent issuance fees for the citizenship certificate and identity documents together typically total a few hundred Singapore dollars per person. On timeline, processing commonly takes several months to around a year, depending on the case. Confirm current requirements and fees on the ICA website; work-pass matters during the transition remain governed by MOM.

Step-by-step to citizenship

Step one, confirm you meet the PR duration and age criteria and have a strong record of residence and contribution. Step two, assemble and translate all documents. Step three, submit the online application and pay the fee. Step four, respond to any ICA queries and, if approved in principle, complete renunciation of foreign citizenship. Step five, attend the citizenship ceremony to take the oath, then collect your citizenship certificate, identity card and passport.

The Constitution of the Republic of Singapore sets out the framework for the acquisition and renunciation of citizenship, and the process reflects the seriousness of the commitment. Planning the renunciation step early, including checking the renunciation rules of the other country, avoids delays at the final stage.

Common mistakes and gotchas

A common misunderstanding is expecting to keep dual citizenship; adults generally must renounce other nationalities. Another is applying without a settled record of residence and contribution, which weakens the case. A third is underestimating the renunciation logistics, which depend on the other country’s own rules and can take time.

Families should also plan for children carefully, since National Service obligations apply to male citizens and second-generation permanent residents, and the timing of a child’s citizenship can have long-term implications. Taking these into account before applying leads to better decisions.

The citizenship journey in stages

Citizenship usually follows a settled period of permanent residence. In practice the journey runs from work pass, to permanent residence, to citizenship, with each stage building on the record established in the previous one. An applicant with a long, stable PR history, deep family and economic ties, and clear intent to remain presents the strongest case.

ICA assesses each application holistically, weighing contribution, ties and integration. Because citizenship is largely irreversible and involves renouncing other nationalities, applicants should be confident in their long-term commitment to Singapore before applying, rather than treating it as a routine upgrade from PR.

Worked example: costs and the renunciation step

A permanent resident of five years, married with two children, applies for citizenship. The government application and issuance fees total a few hundred Singapore dollars per person. The distinctive step is renunciation: because Singapore does not permit dual citizenship for adults, the applicant must renounce their existing nationality once approved in principle, and the logistics depend on the other country’s rules, which can add weeks or months.

After renunciation, the family attends a citizenship ceremony to take the Oath of Renunciation, Allegiance and Loyalty, then collects citizenship certificates, identity cards and passports. Planning the renunciation early, including checking the other country’s requirements, avoids a bottleneck at the final stage.

National Service and family planning considerations

Families with sons should understand National Service obligations before applying. Male citizens and second-generation permanent residents are generally liable for National Service, and the timing of a child’s citizenship can have long-term implications for education and career planning. These are not reasons to avoid citizenship, but they are factors to weigh deliberately.

Taking advice on the family’s overall position, including the children’s status and any cross-border tax or inheritance considerations, leads to better-informed decisions. Citizenship is a family milestone, and planning it with the whole household in mind produces the smoothest outcome.
