Short answer: before applying for citizenship by investment, the key is your current nationality rules. Mainland China does not recognise dual nationality; Hong Kong has special arrangements; Taiwan generally allows its nationals to hold another nationality.
The three at a glance
| Status | General rule |
|---|---|
| Mainland Chinese residents | The Nationality Law does not recognise dual nationality; those settled abroad who voluntarily take a foreign nationality automatically lose Chinese nationality |
| Hong Kong residents | Hong Kong residents of Chinese descent who take a foreign nationality are generally still treated as Chinese nationals unless they declare a change to the Immigration Department |
| Taiwanese residents | Nationals may generally also hold a foreign nationality, with restrictions for some public offices |
What this means for citizenship by investment
- The Caribbean countries and Turkey generally allow dual citizenship, but that’s only the new country’s side.
- Whether you keep your current nationality depends on your current rules too.
- Hong Kong residents with a foreign passport are generally still treated as Chinese nationals in Hong Kong and the mainland — for example, using Chinese travel documents to cross the border.
