To the best of my knowledge, the Government of Grenada does not share details of its citizenship by investment program and those who apply, with any other nation. Grenada does not have any restrictions with regard to dual or multiple nationalities.

How can I obtain a Grenada passport if my home country doesn’t allow dual citizenship?
I was born in a country that doesn't allow dual citizenship and has strict renunciation laws. How can I navigate the potential conflict between obtaining Grenada citizenship and my current citizenship status? Can I have the Grenada passport while it not showing on any records that my government can access? (I would still like to maintain my original nationality).
