In the Republic of Armenia, acquisition of citizenship is based upon the principle of ius sanguinis and in restricted circumstances upon the principle of ius soli and through naturalisation.
The law establishes the following grounds for the acquisition of Armenian citizenship namely: through recognition of citizenship; by birth; through naturalisation; by resumption; through collective acquisition of citizenship; and on the grounds provided for by the international treaties of the Republic of Armenia.
Armenian citizenship through recognition can be obtained by; citizens of the former Armenian SSR if they meet the requirements prescribed by the law; stateless Armenians permanently residing in the Republic of Armenia; or stateless citizens of other Republics of the former USSR who apply for acquiring the citizenship of the Republic of Armenia before 31 December 2019.
Armenian citizenship in a simplified manner can be granted through naturalisation for a person with an Armenian origin or with an Armenian predecessor. Citizenship of the Republic of Armenia may also be granted to those who render exclusive service to the Republic of Armenia.
Citizens of the Republic of Armenia shall be free to acquire citizenship of another country or countries whilst maintaining their original citizenship. Foreign nationals may, without the requirement of resignation, obtain citizenship of the Republic of Armenia if they meet the requirements prescribed by the law. Persons obtaining dual citizenship, are not obliged to notify the Republic of Armenia.
An Armenian citizen that has obtained dual citizenship is however recognised as a citizen of the Republic of Armenia only. The dual citizen of the Republic of Armenia has the same rights as those are provided for other citizens of the Republic of Armenia and has the same duties and responsibilities except for the cases stipulated by the international treaties or laws of the Republic of Armenia. The Republic of Armenia has agreements on regulating dual citizenship matters such as excluding double taxation, with a number of countries.
