of a country that was still a signatory to the 1963 Strasbourg Convention on Multiple Nationality (i.e. Austria, Denmark, France, Ireland, Italy, Luxembourg, the Netherlands, Norway, Spain or the United Kingdom). Note that the acquisition of the other citizenship had to be voluntary. Being born with another citizenship never led to the loss of Belgian nationality. Therefore, it has always been possible to hold Belgian citizenship and other citizenship(s) by birth. However, the above provisions were all removed from law effective 28 April 2008. A person who voluntarily obtains another nationality after this date will no longer lose their Belgian nationality, regardless of the nationality acquired. Recovery of Belgian nationality A person who has lost their Belgian nationality (other than by deprivation) may recover it by making a recovery declaration (déclaration de recouvrement / verklaring tot herkrijgen). The person must be at least 18 years old AND resident in Belgium for 12 months before making the declaration. The residence period is thus considerably shorter than the usual requirement of 5 or 10 years. The declaration should be made according to the procedure outlined in the "Nationality declarations" section below. Approximately 50 to 100 people recover Belgian nationality per year. A person who lost their Belgian nationality and satisfies the conditions for recovering it (except for the 12 month residence requirement) has the right to enter and live in Belgium indefinitely (even without ever making a recovery declaration, if the person does not wish to do so). This rarely-publicised and extremely rarely-exercised right is provided for under Article 10 of the Loi sur l'accès au territoire, le séjour, l'établissement et l'éloignement des étrangers of 15 December 1980. Recovery after renunciation A person who renounced their Belgian nationality must describe the circumstances of the renunciation and their reasons for wanting to recover nationality. The Crown Prosecutor has some latitude to approve or decline such applications based on the description/reasons provided. Recovery after residence overseas A person who lost their Belgian nationality following residence overseas (as per the criteria described above under "Loss of Belgian nationality") must normally return to Belgium and reside in Belgium for 12 months before making a recovery declaration. However, since 2018, it is also possible to make a recovery declaration while resident abroad, but only if the person can satisfactorily explain why it was impossible for them to make the declaration of conservation between the ages of 18
