Dual Citizenship

Estonia maintains a restrictive stance on dual citizenship, though the practical application has softened over time.

Legal position:

The Estonian Constitution (Section 8) states that no person may be deprived of citizenship acquired by birth. A person who acquires Estonian citizenship by birth cannot lose it involuntarily.
Persons who acquire Estonian citizenship by naturalization must renounce their prior citizenship. If they subsequently acquire a foreign citizenship voluntarily, they may be deemed to have implicitly renounced their Estonian citizenship.
Estonian law does not explicitly prohibit dual citizenship for citizens by birth but requires naturalized citizens to hold only Estonian citizenship.

Practice:

Estonian citizens by birth who acquire a foreign nationality are not actively pursued for renunciation. Estonia does not have an enforcement mechanism to strip birth citizens of their nationality for acquiring another.
Citizens by naturalization face a stricter regime. Acquiring another nationality after naturalization may trigger proceedings to revoke Estonian citizenship.
Children who acquire Estonian citizenship at birth AND simultaneously acquire another citizenship by birth (e.g., from the other parent) are tolerated as dual citizens. The government has declined to require them to choose.

Political debate: There has been ongoing discussion about formally legalizing dual citizenship, particularly to maintain ties with the Estonian diaspora. As of 2026, no legislative reform has been enacted.

e-Residency distinction: Estonia’s e-Residency program grants a digital identity for business purposes. It confers no immigration rights, no residency rights, and no path to citizenship. e-Residents are not Estonian residents or citizens.

Acquisition of Nationality

By Birth (Jus Soli)

Estonia applies a very limited jus soli:

A child born in Estonia acquires Estonian citizenship at birth only if both parents are stateless persons or persons of undetermined citizenship who have been lawfully resident in Estonia for at least 5 years before the child’s birth, and the child does not acquire any other citizenship at birth (Section 5(1) of the Citizenship Act, as amended in 2015).
Foundlings discovered on Estonian territory are deemed Estonian citizens until another nationality is established.

Context on “persons with undetermined citizenship”: Following the restoration of independence in 1991, approximately one-third of Estonia’s population (primarily ethnic Russians who had settled during the Soviet occupation) were not granted automatic citizenship. They were classified as persons with undetermined citizenship (hallmaaramatata kodakondsusega isik) and issued grey passports. Their children born in Estonia after 1992 may acquire citizenship through the provision above or through naturalization.

By Descent (Jus Sanguinis)

Estonian citizenship is acquired automatically at birth if (Section 5):

At least one parent is an Estonian citizen at the time of the child’s birth.
This applies regardless of where the child is born.
No registration is required for the citizenship to take effect, though registration at an Estonian consulate is necessary for births abroad.

Continuity principle: Estonia views its citizenship as continuous from the pre-1940 Republic. Persons who were Estonian citizens (or their descendants) before the Soviet occupation on 16 June 1940 are entitled to Estonian citizenship regardless of what occurred during the occupation period.

By Adoption

A child under 15 adopted by an Estonian citizen acquires Estonian citizenship if:

The adoption is recognized under Estonian law.
The child is under 15 at the time of the adoption.
At least one adoptive parent is an Estonian citizen.

Adults adopted by Estonian citizens do not acquire citizenship through adoption.

By Marriage

Marriage to an Estonian citizen does not automatically confer citizenship and does not create a separate facilitated pathway. The foreign spouse must naturalize through the standard process. Marriage is not a basis for reducing the residency requirement.

By Naturalization (Residency)

Standard pathway (Sections 6—9):

Requirement	Details
Lawful residence	At least 8 years in Estonia, of which at least the last 5 years must be on a permanent residence basis
Language	B1 Estonian (CEFR) — must pass the Estonian language proficiency exam at B1 level (reading, writing, listening, speaking)
Civics knowledge	Pass an examination on the Estonian Constitution and the Citizenship Act
Permanent legal income	Must have a lawful and permanent source of income supporting the applicant and dependents
Loyalty to the Estonian state	Must take an oath of loyalty
Renunciation of prior citizenship	Must be released from prior citizenship before Estonian citizenship is granted. Proof of renunciation or release must be submitted.
Fee	No state fee for the naturalization process itself (examination fees were abolished)

Simplified naturalization for minors:

A child under 15 born in Estonia to parents who are stateless or of undetermined citizenship may acquire Estonian citizenship through a simplified procedure initiated by the parents (Section 13^2). Requires both parents to have been lawfully resident for at least 5 years. No language or civics test for the child.

Exemptions from language/civics test:

Persons who completed secondary or higher education in Estonian.
Persons with disabilities preventing them from taking the exams.

Loss and Renunciation

Voluntary Renunciation

An Estonian citizen may renounce citizenship by filing an application with the Police and Border Guard Board (Section 23), provided:

They hold another nationality or have been assured one.
Renunciation will not render them stateless.

The Government decides on renunciation applications. Processing time: 3—6 months.

Involuntary Loss

Ground	Details
Entry into foreign government, military, or intelligence service	An Estonian citizen who enters the government, armed forces, or intelligence service of a foreign state without permission from the Estonian Government may lose citizenship (Section 28).
Acquisition by fraud	Citizenship obtained through false information or fraud may be revoked (Section 28).
Voluntary acquisition of foreign citizenship (naturalized citizens)	A naturalized Estonian citizen who voluntarily acquires another citizenship may be deemed to have forfeited Estonian citizenship. Citizens by birth are not subject to this rule.

Constitutional protection: Section 8 of the Constitution prohibits depriving any person of citizenship acquired by birth. This means citizens by birth cannot be stripped of their citizenship under any circumstances.

Restoration of Nationality

For persons who held Estonian citizenship and lost it:

Former Estonian citizens may apply for restoration of citizenship (Section 15). The standard naturalization requirements (residence, language, civics) apply, but the process may be facilitated.
Persons who were Estonian citizens before the 1940 Soviet occupation, and their descendants, are entitled to citizenship as a matter of right under the continuity doctrine. They do not need to naturalize — they need only register their citizenship.

For descendants of pre-1940 citizens:

Must provide documentary evidence of the ancestor’s Estonian citizenship (birth certificates, census records, pre-1940 citizenship documents).
Application to the Police and Border Guard Board or Estonian consulate.
No residency, language, or civics requirement.
Dual citizenship is tolerated for these applicants (as they are citizens by birth/descent, not naturalization).

Stateless Persons and Foundlings

Foundlings discovered on Estonian territory are deemed Estonian citizens until another nationality is established (Section 5).
Stateless children born in Estonia to parents who are stateless or of undetermined citizenship and have resided lawfully for 5+ years may acquire Estonian citizenship (2015 amendment).
Persons with undetermined citizenship (grey passport holders) may naturalize through the standard process. Approximately 65,000 persons still hold undetermined citizenship status as of 2025 (down from over 100,000 in the 2000s).
Estonia is a party to the 1954 Convention relating to the Status of Stateless Persons and the 1961 Convention on the Reduction of Statelessness.
