Citizenship in Estonia
Naturalisation timelines, tests, and dual nationality
Naturalisation requires roughly eight years of residence in Estonia, of which at least the last five have been on the basis of a long-term or permanent residence right, together with a state examination in the Estonian language at the B1 level and a separate examination on the Constitution and the Citizenship Act. Estonia does not accept dual citizenship for naturalised citizens, so the previous nationality is normally given up.

The conditions in outline
- Age of at least fifteen, with children able to acquire citizenship through their parents.
- Roughly eight years of residence in Estonia, of which at least the last five have been permanent, and residence in the country in the year before applying.
- A registered permanent place of residence in Estonia.
- Proof of Estonian at the B1 level through the state examination, unless exempted.
- A pass in the examination on the Constitution and the Citizenship Act.
- A permanent legal income, and loyalty to the Estonian state, evidenced by an oath.
Why the language examination is the hard part
The B1 state examination tests listening, reading, writing and speaking in a language that is Finno-Ugric, unrelated to English or the Romance and Slavic languages, and grammatically demanding, with a large case system. Preparation is commonly measured in years rather than months for an adult learner, and free or subsidised preparation courses are provided by the state precisely because the barrier is recognised.
The constitutional examination is a smaller obstacle. It is based on published material about the Constitution and the Citizenship Act, and it is taken in Estonian, which means it is in practice a second language test.
The dual citizenship rule
A person who acquires Estonian citizenship by naturalisation is expected to release themselves from any other citizenship. Estonian citizenship acquired at birth is treated differently and cannot be removed, which produces the anomaly that a person born Estonian may hold another nationality while a naturalised citizen may not.
For an applicant whose original state does not permit renunciation, or for whom losing that nationality carries a real cost, this rule is often decisive, and many long-term residents remain permanently on long-term resident status instead.
Language politics in context
Roughly a quarter of the population speaks Russian as a first language, concentrated in Tallinn and in the north-east around Narva. Language requirements for residence, citizenship and public employment are a continuing political question rather than a settled technical matter, and the school system has been moving toward Estonian-language instruction.
A newcomer is not a party to that debate, but it explains why language conditions are enforced strictly and why they are unlikely to be relaxed.
