Costa Rican nationality law

Costa Rican nationality law is regulated by the Options and Naturalizations Act (Spanish: Ley de Opciones y Naturalizaciones), which was originally named the Immigration and Naturalization Act and established under the 1949 Constitution.^[1] These laws determine who is, or is eligible to be, a citizen of Costa Rica. The legal means to acquire nationality and formal membership in a nation differ from the relationship of rights and obligations between a national and the nation, known as citizenship.^[2][3][4] Costa Rican nationality is typically obtained either on the principle of jus soli, i.e. by birth in Costa Rica; or under the rules of jus sanguinis, i.e. by birth abroad to at least one parent with Costa Rican nationality. It can also be granted to a permanent resident who has lived in Costa Rica for a given period of time through naturalization.^[5]
