"Singapore Citizenship is the highest form of immigration status in Singapore, granting full legal rights including voting rights, a Singapore passport, and access to all public services and schemes. Singapore does not permit dual citizenship — Singaporeans who acquire foreign citizenship must renounce their Singapore citizenship, and foreigners who naturalise must renounce their prior citizenship."
Key Facts
Eligibility: must be a Singapore PR for at least 2 years before applying (spouses of SC may apply directly)
Singapore does not allow dual citizenship — renunciation of prior nationality is required upon naturalisation
Singapore Citizen children under 21 at the time of parent's naturalisation may become citizens simultaneously
Processing time: typically 12–24 months from PR grant
ICA evaluates: depth of integration, length of PR status, national service completion (for male applicants), and commitment to Singapore
SC and Singapore PR — What You Need to Know
PR is the required intermediate step before Citizenship. Applicants who approach PR with a long-term Citizenship plan in mind — particularly those from countries with meaningful dual citizenship implications (Japan, Korea, India, Indonesia) — should factor the renunciation decision into their planning from the outset. The quality of integration demonstrated during the PR period directly informs the Citizenship application.

Singapore Permanent Residency (PR) is an immigration status that grants foreign nationals the right to live and work in Singapore indefinitely, with fewer restrictions than work pass holders but fewer rights than Singapore Citizens. PR is valid for 5 years initially and must be renewed through a Re-Entry Permit.
A Re-Entry Permit (REP) is the document that allows Singapore PRs and Citizens to re-enter Singapore after travelling abroad. For PRs, it is also the mechanism by which PR status is maintained and renewed — without a valid REP, a PR holder who leaves Singapore may lose their PR status upon return.
National Service (NS) is Singapore's mandatory military or civil defence service requirement for male Singapore Citizens and first-generation male PRs. It represents Singapore's commitment to collective defence and is deeply embedded in the nation's social identity.
Dual citizenship means holding citizenship in two countries at the same time. Singapore does not generally permit dual citizenship for adults acquiring or retaining Singapore Citizenship.
