You can become a citizen of Grenada by financially investing in the country, either by making a cash donation or through purchasing pre-approved real estate on the island. Applicants can apply for citizenship through the country’s citizenship by investment program. If you are at least 18 years old and are healthy, can afford the cost of citizenship (the minimum price is $150,000 USD) as well as all the associated fees, and pass an extensive background check, you will likely receive Grenadian citizenship.
