Report on Citizenship Law: Tanzania Where one’s application is successful, they will have to renounce any citizenship or claim of protection they may enjoy from another country and also take an oath of allegiance96. Naturalisation of minors: The Minister may, if there are circumstances he or she considers special, cause the naturalisation of a minor child. Although, for all other non-citizen minors, their parents or guardians may apply for their naturalisation97 upon providing the following requirements98: the parent’s or guardian’s proof of citizenship of parent or guardian; the birth certificate of a child; a valid immigration status for the child; passport photographs, and a nonrefundable submission fee. Naturalisation through marriage: A foreign woman married to a Tanzanian citizen, may at any time during the lifetime of her husband apply for naturalisation99. Yet, a woman who before her marriage to a Tanzanian citizen, renounced or was deprived of her Tanzanian citizenship under the law, can only be naturalised with the Minister’s approval100. In applying for naturalisation, the woman must also submit a marriage certificate registered in Tanzania, proof of the husband’s citizenship, a valid passport, proof of immigration status, and passport photographs101. The Minister is not obliged to give reasons for his or her decision to grant or not to grant an application, the decision is final and not subject to any judicial appeal or review102. This is one of the provisions of the TCA with more observable restrictions on citizenship acquisition. In the previous law, a woman married to a Tanzanian citizen was entitled to apply for registration whether or not the citizen husband was alive, and whether or not the marriage was subsisting. The current law apparently disqualifies widowed or divorced foreign wives of Tanzanian husbands. Furthermore, and as a carry-over from the previous law, the fact that the law fails to provide for foreign husbands married to Tanzanian women cannot be ignored. Reportedly, TANU had been concerned with the possibility of foreign men, who through marriage, tried to gain citizenship for expedient reasons103. 3.2 Prohibition of dual citizenship for adults Under the TCA, once a person turns eighteen years and they hold another citizenship in addition to the Tanzanian citizenship, they shall be deemed to have ceased to be a Tanzanian citizen, unless they had previously renounced their other citizenship and taken the oath of allegiance104. The cessation of Tanzanian nationality also applies to persons who turned eighteen before and after the Union day and continued to hold the citizenship of another country in addition to either their Tanganyikan or Zanzibari citizenship105. The law goes ahead to provide for cessation of citizenship for anyone who voluntarily acquires the citizenship of another country after they turn eighteen106. 96 TCA, section 9 (3).
