[6] Grenada was previously an associated state of the United Kingdom and local residents were British subjects.
[17] The primary applicant must be 18 years of age or older and up to four family members (parents, grandparents, siblings, spouse, or children) must make a minimum investment, which in 2020 was US$150,000 for a single applicant and US$200,000 for a family of four persons, to the National Transformation Fund.
[21] Grenada allows a special naturalisation process for people who are political refugees or stateless, at the discretion of the Minister.
[25] Denaturalisation may occur if a person obtained nationality through fraud, false representation, or concealment; if they have committed acts of treason; if they have committed acts of disloyalty or service to a foreign government; if they are found guilt of certain criminal offences; and in the case of nationality by investment for failure to meet requirements of the program.
[27] Grenada was encountered by Spain in 1498, however no attempts were made to inhabit it by them because of the warlike nature of the indigenous Kalinago, or Carib, people living there.
[28] In 1626, the Compagnie de Saint-Christophe was chartered by Louis XIII of France's chief minister, Cardinal Richelieu to colonize the Lesser Antilles.
[29][30] In 1627 a royal patent was issued by Charles I of England to James Hay, 1st Earl of Carlisle granting rights over the islands situated between 10° and 20° north latitude, creating a competing claim for Grenada.
[31] In 1650, Jacques Dyel du Parquet purchased land from the Caribs and established a permanent French settlement.
[37] In Britain, allegiance, in which subjects pledged to support a monarch, was the precursor to the modern concept of nationality.
[60] Because of administrative problems and a lack of evidence that the apprentice program was preparing former slaves for freedom, Britain ended all apprenticeships effective on 1 August 1838.
[63] In 1833, Grenada was included in the confederation of the British Windward Islands, along with Barbados, St. Vincent, and Tobago, under the authority of a single governor, but with individual legislatures.
[67] The uniform law, which went into effect on 1 January 1915, required a married woman to derive her nationality from her spouse, meaning if he was British, she was also, and if he was foreign, so was she.
[70] The statute reiterated common law provisions for natural-born persons born within the realm on or after the effective date.
[71] For those born abroad on or after the effective date, legitimacy was still required, and could only be derived by a child from a British father (one generation), who was natural-born or naturalised.
[74] Because of a rise in statelessness, a woman who did not automatically acquire her husband's nationality upon marriage or upon his naturalisation in another country, did not lose their British status after 1933.
[75] The 1943 revision allowed a child born abroad at any time to be a British national by descent if the Secretary of State agreed to register the birth.
[78] The federation, which included Barbados, the British Leeward Islands, the British Windward Islands, Jamaica, and Trinidad and Tobago, was typically seen by its supporters as a means to use a federal structure to gain national independence and eventual recognition as a Dominion.
The federation was unable to develop a unified nationality scheme, as member states tended to identify with their specific island, rather than by region.
