Lithuanian Citizenship Law: Current Overview and Ongoing Developments as of 2025

1. Dual Citizenship Referendum: Outcome and Implications

On May 12, 2024, Lithuania held a constitutional referendum alongside the presidential elections, aiming to amend Article 12 of the Constitution to permit dual citizenship. While 74.49% of participating voters supported the amendment, the referendum failed due to insufficient voter turnout, falling short of the required threshold.

Implications:

  • The constitutional prohibition on dual citizenship remains in effect.

  • Lithuanian citizens acquiring another nationality after March 11, 1990, are generally required to renounce their Lithuanian citizenship.

  • Exceptions continue to apply for individuals who left Lithuania before 1990 and their descendants.


2. Enhanced National Security Measures in Citizenship Law

In response to geopolitical tensions, Lithuania has introduced amendments to its citizenship laws to safeguard national security.

Key Provisions:

  • Revocation of Lithuanian citizenship for individuals with dual nationality who pose a threat to national security.

  • Denial of citizenship to those supporting foreign states that endanger Lithuania or its allies.

  • Revocation of citizenship for individuals backing actions by foreign states that violate international law.

These measures apply regardless of how citizenship was acquired and underscore Lithuania’s commitment to protecting its national interests.


3. Streamlined Procedures for Dual Citizenship Documentation

To enhance administrative efficiency and prevent misuse, Lithuania has revised its procedures for dual citizenship documentation.

Updated Procedures:

  • Citizens acquiring another nationality must notify the Lithuanian Migration Department within two months.

  • The deadline for submitting documents to prove entitlement to dual citizenship has been reduced from six to three months.

  • Failure to provide necessary documentation within the stipulated timeframe may result in the initiation of procedures to revoke Lithuanian citizenship.

These changes aim to ensure timely compliance and uphold the integrity of the citizenship process.

The following table summarizes the current eligibility criteria for dual citizenship in Lithuania:
