Will I need to give up my current citizenship to take the NDF route?

Antigua and Barbuda recognises dual citizenship, meaning you are not required to renounce your current nationality when you naturalise through the National Development Fund. Most applicants hold their original passport alongside the Antigua and Barbuda one.

The limiting factor is your home country's law, not Antigua's. Some countries do not allow their citizens to hold a second nationality, or require notification. Check your own country's rules before applying, because a restriction there could force a choice between the two.
