Can You Lose Belgian Citizenship?

Belgian citizenship is generally considered robust and secure, but there are specific circumstances under which a person can lose their Belgian nationality. Understanding these scenarios is crucial, especially for individuals who hold dual or multiple nationalities, as Belgium allows dual citizenship. Below, we’ll explore the conditions under which Belgian citizenship may be lost, along with important legal considerations.
1. Voluntary Renunciation of Belgian Citizenship
One of the most straightforward ways to lose Belgian citizenship is by voluntarily renouncing it. This process requires a formal application and approval from the Belgian authorities.
Key Points:
- Eligibility: You must have another nationality to renounce Belgian citizenship, as Belgium does not allow statelessness.
- Process: Submit a written declaration to the Belgian embassy or consulate in your country of residence.
- Reasons for Renunciation: Common reasons include simplifying legal matters, avoiding tax obligations, or aligning with personal identity.
Important Note:
Renouncing Belgian citizenship is irreversible unless you go through the naturalization process again, which can be lengthy and complex.
2. Acquisition of Another Nationality (Before 2008)
Prior to April 28, 2008, Belgian law stipulated that acquiring another nationality could result in the automatic loss of Belgian citizenship, unless special permission was granted beforehand. However, this rule no longer applies to those who acquired foreign nationality after this date.
Key Points:
- If you obtained another nationality before 2008 without seeking authorization, you may have inadvertently lost your Belgian citizenship.
- For those affected, it’s possible to reclaim Belgian nationality through a simplified procedure if certain conditions are met.
3. Serving in a Foreign Military
Belgium prohibits its citizens from serving in the armed forces of another country without prior consent, particularly if that service conflicts with Belgium’s interests.
Key Points:
- Loss of Citizenship: If a Belgian citizen enlists in a foreign military engaged in hostilities against Belgium or its allies, they risk losing their nationality.
- Exceptions: Serving in international organizations like NATO or the UN typically does not lead to loss of citizenship.
4. Fraudulent Acquisition of Citizenship
If Belgian citizenship was obtained through fraudulent means—such as providing false information during the naturalization process—the government has the authority to revoke it.
Key Points:
- Investigation: Authorities may investigate cases where fraud is suspected, even years after citizenship is granted.
- Consequences: Revocation results in the loss of all rights associated with Belgian nationality, including passport privileges.
5. Dual Nationals and Loss of Other Citizenship
While Belgium permits dual or multiple citizenships, complications can arise if the other country involved has stricter rules regarding nationality.
Key Points:
- Some countries require renouncing previous nationalities upon becoming a citizen, which could indirectly affect your status as a Belgian citizen.
- Always verify the laws of both Belgium and the other country to avoid unintended consequences.
6. Children Born Abroad to Belgian Parents
Belgian children born abroad to Belgian parents may lose their citizenship if certain conditions aren’t met.
Key Points:
- Registration Requirement: Parents must register the child’s birth at a Belgian consulate within five years; otherwise, the child might not retain Belgian nationality.
- Retention Option: After turning 18, the individual has five years to declare their intention to keep Belgian citizenship.
7. Long-Term Absence Without Maintaining Ties
Although rare, prolonged absence from Belgium without maintaining ties to the country could theoretically raise questions about an individual’s commitment to their Belgian identity. However, this alone is unlikely to result in loss of citizenship.
How to Prevent Losing Belgian Citizenship
To safeguard your Belgian nationality, consider the following steps:
- Stay Informed: Keep up-to-date with changes in Belgian nationality laws.
- Maintain Documentation: Ensure your birth and marriage records are registered correctly.
- Seek Legal Advice: Consult a lawyer specializing in immigration or nationality law if you’re unsure about your status.
Reacquiring Belgian Citizenship
If you’ve lost Belgian citizenship, it may still be possible to regain it under certain conditions:
- Naturalization: Apply for naturalization after residing legally in Belgium for a specified period (usually five years).
- Simplified Procedure: Former citizens who lost their nationality due to pre-2008 regulations may qualify for a streamlined reacquisition process.
