Citizenship by Adoption — Child Adopted by Lithuanian Citizen(s) (Article 17)
A child adopted by Lithuanian citizen(s) acquires Lithuanian citizenship automatically from the date the adoption takes legal effect (Art 17(1), Law XI-1196, 2024-01-01 consolidated). Conversely, a Lithuanian-citizen child adopted by foreign citizen(s) retains Lithuanian citizenship irrespective of any foreign citizenship conferred by the adoption (Art 17(2)). The operative article is Art 17 — NOT Art 16 (which governs foundlings/children of unknown parents). No language exam, Constitution exam, or residence requirement applies; citizenship follows the adoption decree. Dual-citizenship outcomes for adopted children under 18 interact with Art 7(11) of the single-nationality framework.
