 In the mid-1950s, when oil refineries were machined in Grenada and had reduced their operating income, the US allowed a group of oil workers in Grenada to emigrate to this country.These men and women managed to immigrate to the US legally by various means.Some had made significant relationships at work in the oil enclave or in the naval base (in Chaguaramas, Trinidad), and their bosses gave references to American employers.
