Visa for a child with dual citizenship

I am citizen of Tanzania working abroad on a work permit and have a four year old child born in the country where I am currently working and staying. According to the citizenship of this country, my child has become a citizen here by virtue of birth. My understanding is that the laws of Tanzania do not allow dual citizenship but allow a child to acquire citizenship by birth from one of his parent who is a citizen of Tanzania. I am planning to visit my country Tanzania during Easter vacation and am wondering if my child who is currently having dual citizenship needs a visa for him to enter Tanzania. Please guide me.

Regulation 10(2) of the Immigration (Visa) Regulations, 2016 provides the answer to your question. A child with dual citizenship of Tanzania and another country does not requires visa to enter Tanzania. However, that right will cease when the child attains the age of 18 years. According to the Tanzania Citizenship Act, a child with dual citizenship is deemed to have ceased to be a citizen of Tanzania upon attaining the age of 18 years unless he renounces his citizenship of the other country and takes the oath of allegiance.
