Singapore
You may apply after two years as a permanent resident. Approval remains selective and is not automatic.

What the headline leaves out
When the clock starts
The public eligibility threshold begins after permanent residence is granted, not on the date of first arrival in Singapore.
The catch
Two years creates eligibility to apply, not an entitlement to citizenship. Singapore assesses the application and does not generally permit adult dual citizenship.
