Does Saint Lucia allow dual citizenship if I already hold another passport?

Saint Lucia allows dual citizenship, meaning you can generally become a citizen of Saint Lucia while retaining your current citizenship. The country does not require you to renounce another nationality to take part in the investment programme.

However, whether you can legally hold two citizenships also depends on the laws of your country of origin. Some countries restrict or do not recognise dual citizenship, so you should check your home country's rules before applying.
