Acquiring Guinean nationality through long-term residence, marriage or other grounds under the nationality code.
Expert reviewed Official guidance referenced
Under review — check current rules
Residence period (~5 years), marriage-based timelines (reported as five years of marriage and three years of residence), and Guinea's current dual-citizenship position come from secondary sources and conflict between sources. All figures and the governing authority/URL for nationality must be verified against Guinea's official nationality code / Ministry of Justice before publishing; no official government URL for naturalisation was confirmed in this research.
