Dual Citizenship

Sierra Leone has permitted dual citizenship since the passage of the Citizenship (Amendment) Act 2006. Prior to this amendment, Sierra Leonean citizens who acquired a foreign nationality automatically lost their Sierra Leonean citizenship.

The 2006 amendment allows Sierra Leonean citizens to hold the citizenship of another country without losing their Sierra Leonean nationality. Foreign nationals who naturalize in Sierra Leone are similarly permitted to retain their existing citizenship.

Restrictions on dual citizens in public office: Despite the legal permission for dual citizenship, the 1991 Constitution contains provisions that bar dual nationals from holding certain senior government positions. Section 76 requires that candidates for the Presidency and Vice Presidency be citizens of Sierra Leone “by birth or descent” and — critically — not hold citizenship of any other country. Similar restrictions apply to Members of Parliament and other high officials.

This restriction has been a persistent source of political controversy. During the 2018 and 2023 general elections, the citizenship status of several candidates was challenged on dual nationality grounds. The tension between the 2006 amendment (permitting dual citizenship generally) and the 1991 Constitution (restricting dual citizens from office) remains unresolved.

The racial criterion: The most distinctive and controversial aspect of Sierra Leonean citizenship law is the racial requirement for citizenship by birth. The 1991 Constitution restricts citizenship by birth to persons of “Negro-African” descent — a provision that affects the long-established Lebanese, Syrian, Indian, and mixed-heritage communities who have lived in Sierra Leone for generations. This has drawn sustained criticism from the African Commission on Human and Peoples’ Rights and international human rights organizations.

Acquisition of Nationality

By Birth (Jus Sanguinis with Racial Criterion)

Under the 1991 Constitution (Section 27), a person born in or outside Sierra Leone is a citizen by birth if their father or grandfather was born in Sierra Leone and is or was of Negro-African descent. This racial prerequisite is a constitutional requirement that has been challenged but not yet amended.

Who is affected:

Persons of Lebanese, Syrian, Indian, Chinese, or European descent born in Sierra Leone to families who have lived in the country for multiple generations are excluded from citizenship by birth.
Mixed-heritage individuals must satisfy the descent test through the patrilineal line.
The practical impact falls most heavily on the Lebanese-Sierra Leonean community, which numbers approximately 5,000—10,000 and has been present in Sierra Leone since the late 19th century.

These excluded groups may only acquire citizenship through naturalization, with its 15-year residency requirement.

By Descent

Children born outside Sierra Leone to a father or grandfather who is a Sierra Leonean citizen of Negro-African descent acquire citizenship automatically. Registration at a Sierra Leonean mission abroad is advisable to obtain documentary proof, but the citizenship is acquired by operation of law.

Gender asymmetry: The constitutional text references the father or grandfather, creating a patrilineal bias. While reforms have been discussed, particularly following ECOWAS court rulings on gender equality in nationality laws, the constitutional text has not been amended. In practice, maternal-line claims may be accepted in some administrative contexts, but the legal basis remains uncertain.

By Adoption

Sierra Leone does not have a specific statutory provision for automatic citizenship acquisition through adoption. Adopted children may apply for naturalization through the standard process, and the adoption relationship would be considered favorably. The Adoption Act provides a legal framework for adoption, but it does not address citizenship transmission.

By Marriage

A foreign woman who marries a Sierra Leonean citizen of Negro-African descent may apply for citizenship by registration — a simplified process compared to full naturalization. The application is made to the Minister responsible for internal affairs.

Gender disparity: Foreign men who marry Sierra Leonean women do not benefit from an equivalent simplified registration pathway. They must naturalize through the standard 15-year process. This gender asymmetry has been criticized by the CEDAW Committee and human rights organizations.

Requirements for registration through marriage:

The marriage must be legally valid.
The applicant must be of good character.
The applicant must intend to reside in Sierra Leone.
There is no specified minimum duration of marriage before application.

By Naturalization

Requirement	Details
Lawful residence	15 years of continuous residence (one of the longest in Africa)
Good character	Good character attested by at least two references who are Sierra Leonean citizens
Language	Adequate knowledge of a language in common use in Sierra Leone (Krio, Mende, Temne, or English)
Financial contribution	Must have made a tangible contribution to Sierra Leone or intend to reside permanently and contribute to the welfare of the community
Renunciation	Not required since the 2006 amendment
Oath of allegiance	Required; administered before a court
Application	Submitted to the Minister responsible for internal affairs

The 15-year residency requirement is one of the longest in the world, let alone in Africa. The President has discretionary power to waive requirements in exceptional cases, particularly for persons who have rendered distinguished service to Sierra Leone, but this power is exercised rarely.

Important: Even naturalized citizens remain subject to the racial distinction in the Constitution. A naturalized citizen of non-Negro-African descent cannot later claim the rights reserved for citizens “by birth” under the Constitution.

Loss and Renunciation

Voluntary renunciation: A citizen who holds another nationality may renounce Sierra Leonean citizenship by written declaration to the competent authority. The renunciation takes effect upon registration.

Involuntary loss (deprivation): Citizenship by naturalization may be revoked if:

Obtained by fraud, false representation, or concealment of a material fact.
The person has shown disloyalty to Sierra Leone by act or speech.
The person has been sentenced to imprisonment for a term of 12 months or more within 7 years of naturalization.
The person has resided outside Sierra Leone continuously for 7 or more years without maintaining registration at a Sierra Leonean consulate.

Citizens by birth generally cannot be deprived of citizenship unless the acquisition was based on fraudulent claims of descent.

Restoration of Nationality

Persons who lost Sierra Leonean citizenship under the pre-2006 law (by acquiring a foreign nationality) may apply for restoration. The 2006 amendment effectively opened the door for members of the diaspora to reclaim their citizenship. Applications are submitted to the Ministry of Internal Affairs.

Key points:

Restoration is discretionary, not automatic.
The applicant must demonstrate their prior citizenship and the circumstances of loss.
Processing times vary but typically range from 6 to 18 months.
There is no residency requirement for restoration (unlike for new naturalizations).

Stateless Persons and Foundlings

The Constitution does not contain a specific provision for foundlings. However, a child born in Sierra Leone whose parents are unknown would generally be presumed to have the nationality of Sierra Leone, subject to the racial criterion in the Constitution — a problematic gap, as a foundling of unknown descent cannot definitively satisfy the “Negro-African descent” requirement.

Sierra Leone is a party to the African Charter on the Rights and Welfare of the Child, which includes provisions on the right to nationality. The practical application of these provisions for foundlings remains underdeveloped.
