🇸🇬 Singapore · Citizenship
Naturalization and citizenship-by-investment: residence years, language and civics tests, dual-citizenship rules, and multi-passport planning.
Quick answer
Singapore citizenship generally requires being a permanent resident for at least two years (or being married to a citizen), economic contribution and intention to settle. Singapore does not allow dual citizenship for adults.
Singapore citizenship is granted by the Immigration & Checkpoints Authority (ICA), usually to those who have been permanent residents for at least two years (most successful applicants longer), are of good character, intend to live in Singapore permanently and can contribute and integrate. Singapore does not recognise dual citizenship: approved applicants must renounce all other citizenships before or at the citizenship ceremony.
- You must already be a Singapore PR — usually for at least two years (most approved applicants have held PR longer).
- ICA assesses holistically: good character, economic contribution, family ties, integration and intention to settle.
- Singapore does not allow dual citizenship — you must renounce any other citizenship before/at the citizenship confirmation.
- Apply online via ICA e-Service; processing typically takes several months.
