"Minimum" is a cited investment threshold in its stated currency. A USD figure appears only when a supported conversion is on file; "—" means no supported amount is on file, not that it is free. "To citizenship" counts the years of residence before a naturalisation application. A zero-year entry states no residence wait; citizenship still needs a separate decision.
