Dual Citizenship

Burundi’s position on dual citizenship evolved significantly with the 2005 Constitution, adopted as part of the Arusha Peace and Reconciliation Agreement that ended the civil war.

Current framework:

  • Article 12 of the 2005 Constitution states that no Burundian may be deprived of their nationality of origin. This has been interpreted to mean that Burundians by birth or descent retain Burundian nationality even if they acquire a foreign citizenship.
  • The 2018 constitutional revision maintained this provision.
  • Naturalized citizens are subject to stricter rules: acquisition of another nationality after naturalization may result in loss of Burundian citizenship.
  • The Nationality Code of 1971 (still formally in force but superseded in part by the Constitution) contains provisions requiring renunciation, but constitutional supremacy means these provisions are largely unenforceable against citizens by origin.

Practical reality: Many Burundians in the diaspora (particularly in Belgium, France, Canada, Tanzania, and the Democratic Republic of Congo) hold dual nationality. The government has generally not pursued enforcement against citizens by origin, consistent with the constitutional guarantee.

Historical context: The dual citizenship provision was a critical component of post-conflict reconciliation. Hundreds of thousands of Burundians fled during the civil war (1993—2005) and the earlier 1972 genocide. Ensuring that exiled populations retained their nationality was essential to the peace process.

Acquisition of Nationality

By Birth (Jus Sanguinis)

Burundi follows a predominantly jus sanguinis system. Birth on Burundian territory does not automatically confer nationality.

Article 2 of the Nationality Code:

A child acquires Burundian nationality at birth if:

  1. The father is Burundian at the time of birth (under the original 1971 Code), OR
  2. The mother is Burundian at the time of birth (under the gender-equality provisions of the 2005 Constitution).

Key notes:

  • The 1971 Code originally transmitted nationality through the father only. The 2005 Constitution’s equal protection provisions effectively extended transmission to mothers, though a comprehensive legislative update to the Nationality Code has not been enacted.
  • Children born in Burundi to two foreign parents do not acquire Burundian nationality at birth.

By Descent

Children born outside Burundi to at least one Burundian parent acquire nationality at birth, subject to registration with Burundian consular authorities.

Generational limit: No explicit generational cutoff exists in the legislation, but the chain of transmission requires each generation to establish parentage through official documentation.

By Adoption

The Nationality Code provides for acquisition of Burundian nationality through adoption:

  • A minor child (under 18) adopted by a Burundian citizen may acquire Burundian nationality.
  • The adoption must be legally recognized under Burundian law.
  • The Minister of the Interior must approve the nationality acquisition.

By Marriage

Marriage to a Burundian citizen does not confer automatic nationality. A foreign spouse may apply for naturalization under a facilitated pathway.

Requirements:

  • The marriage must have existed for at least 2 years.
  • The applicant must reside in Burundi.
  • Standard naturalization conditions apply (good character, no serious criminal convictions).
  • The original 1971 Code provided automatic acquisition for foreign women marrying Burundian men — this gender-discriminatory provision has been superseded by the 2005 Constitution.

By Naturalization

Standard pathway (Articles 7—12, Nationality Code):

RequirementDetails
Lawful residence10 years of continuous habitual residence in Burundi
AgeAt least 18 years old
CharacterGood moral character; no convictions for serious criminal offenses
LanguageNo formal requirement, but practical knowledge of Kirundi or French is expected
Economic meansMust demonstrate means of subsistence
HealthMust not suffer from contagious diseases (a dated provision still formally in the Code)
ApprovalGranted by presidential decree on recommendation of the Minister of the Interior

Exceptional naturalization: The President may grant Burundian nationality by decree to any person who has rendered exceptional services to Burundi or whose naturalization is in the national interest.

Loss and Renunciation

Voluntary Renunciation

A Burundian citizen may renounce nationality by declaration, provided:

  1. They hold or are assured of acquiring another nationality.
  2. The renunciation is approved by the government.

Constitutional safeguard: Under Article 12 of the 2005 Constitution, a Burundian by origin cannot be deprived of nationality. This creates an asymmetry — while voluntary renunciation is permitted, involuntary deprivation of citizens by origin is constitutionally prohibited.

Involuntary Loss

GroundDetails
Voluntary acquisition of foreign nationality (naturalized citizens only)A naturalized citizen who acquires another nationality may lose Burundian citizenship by government decision
Service in a foreign militaryServing in a foreign armed force without government authorization
FraudNationality obtained through false declarations or fraud may be annulled within 10 years
Acts against the stateNaturalized citizens may be deprived for acts of treason or acts incompatible with Burundian nationality

Important: Citizens by origin (jus sanguinis) are constitutionally protected from deprivation. The loss provisions primarily affect naturalized citizens.

Restoration of Nationality

Former Burundian citizens may apply for reacquisition of nationality:

  1. Citizens by origin who renounced: May reclaim nationality by declaration to the Minister of the Interior. The constitutional guarantee in Article 12 supports a right of return to Burundian nationality for those who are Burundian by origin.
  2. Naturalized citizens who lost nationality: Must reapply through the standard naturalization process.
  3. Post-conflict returnees: The Arusha Agreement and the 2005 Constitution specifically addressed the situation of Burundians who fled during the civil war and the 1972 events. Returnees are entitled to recover their nationality and property rights.

Processing times for restoration vary widely and depend on administrative capacity and political conditions.

Stateless Persons and Foundlings

Burundi is a party to the 1954 Convention Relating to the Status of Stateless Persons but has not ratified the 1961 Convention on the Reduction of Statelessness.

Foundlings: A child of unknown parentage found on Burundian territory is presumed to be of Burundian nationality until proven otherwise (Article 3 of the Nationality Code).

Stateless persons: The Nationality Code does not contain specific facilitated naturalization provisions for stateless persons. UNHCR offices in Bujumbura assist with identification and documentation. Residual statelessness risks exist among certain populations, including persons of mixed Burundian-Congolese or Burundian-Tanzanian parentage in border areas.
