Grounds for Revoking Citizenship

Citizenship revocation (denaturalization) varies by country but common grounds include:

1. Fraud/Misrepresentation: False info, concealed facts during naturalization (e.g., criminal history, identity).
2. Acts of Disloyalty/Treason: Terrorism, espionage, bearing arms against the state, high treason.
3. Voluntary Foreign Naturalization: Some countries (e.g., India, Singapore, Austria) automatically revoke upon acquiring another citizenship (dual citizenship not permitted).
4. National Security Threats: Broad clauses (UK, Australia, France) allow stripping citizenship from dual nationals for terrorism/serious crime.
5. Service in Foreign Military/Government: Without permission.

Process

Usually administrative (ministerial order) or judicial; subject to appeal. International law (1961 Convention) prohibits statelessness—revocation typically requires dual nationality.
