Guyanese nationality law is regulated by the 1980 Constitution of Guyana, as amended; the Citizenship Act of 1967, and its revisions; and various British Nationality laws.[1][2] These laws determine who is, or is eligible to be, a national of Guyana. Guyanese nationality is typically obtained either on the principle of jus soli, i.e. by birth in Guyana; or under the rules of jus sanguinis, i.e. by birth abroad to parents with Guyanese nationality. It can also be granted to persons with an affiliation to the country, or to a permanent resident who has lived in the country for a given period of time through naturalisation.[3] There is not currently a program in Guyana for persons to acquire nationality through investment in the country.[4] Nationality establishes one's international identity as a member of a sovereign nation.[5] Though it is not synonymous with citizenship, for rights granted under domestic law for domestic purposes, the United Kingdom, and thus the Commonwealth, have traditionally used the words interchangeably.[6]
