Can a Person Hold Dual Citizenship?
According to Article 26 of the Nationality Law of Vietnam 2008 and clause 2 of Article 1 of the Amended Nationality Law of Vietnam 2014, the following circumstances result in the loss of Vietnamese nationality. To be specific:
- Voluntarily renouncing Vietnamese nationality;
- Being deprived of Vietnamese nationality;
- Owing taxes to the State or having property obligations to organizations or individuals in Vietnam;
- Being prosecuted for criminal liability;
- Serving a sentence or following a decision by the Court of Vietnam;
- Being temporarily detained awaiting execution of a sentence;
- Abiding by a decision to apply administrative measures such as being assigned to an educational institution, treatment facility, or reformatory;
- Cases as stipulated in Article 35 of the Nationality Law of Vietnam 2008;
- According to international treaties to which the Socialist Republic of Vietnam is a member.
Hence, when your sister got married to a Taiwanese national and completed the procedures to renounce her Vietnamese nationality, she no longer has to be a Vietnamese citizen, and the responsibility of the household head is to remove her name from the family household registration.
Respectfully!
