► on acquisition of nationality in the state concerned. The birth certificate of a child born to non-resident parents will not include nationality. Azerbaijan provides that, if the nationality of the father and the mother are different, the nationality of both parents is indicated in the birth certificate. If the nationality of the parents is not mentioned in their birth certificates or if the birth certificate cannot be presented and this information is not available in the archives of the registry departments, the nationality of that parent is not indicated in the child’s birth certificate. In this case, “Information not provided” is written in the “Nationality” column of the birth certificate. 10. Firewall to prohibit the sharing of information for the purpose of immigration control 90. A very important issue is whether a registrar of civil status will report to the immigration control authorities instances where they have to register the birth of a child of an irregular migrant born in the country. If so, this possibility will discourage irregular migrants to register the birth of their children which makes them extremely vulnerable, for instance to human trafficking, and is contrary to birth registration as a human right. If not, some may consider it as hampering effective immigration control. 91. The attitudes of states in respect of this issue differ considerably. In some states the registry office does not verify the legality of the stay of the child or its parents in the territory of the state. For that reason, birth certificates do not include information which would be of interest for immigration control authorities.97 One state recently abolished the condition of a document of residence registration as a condition for reporting birth.98 92. By way of example, in one state,99 the birth of a child will be registered by making a record and submitting it electronically to the Residents’ Register. These data from the Residents’ Register are submitted to the Foreigners‘ Register, the data of which are directly accessible to the migration authorities. There is no need for the civil registry office to inform the immigration authorities about the registration of a birth of a child without residence status, as these authorities receive this information from the Foreigners‘ Register directly. Conversely, in another state100, if the child born in the country does not have the nationality of the country, registration will be passed on to the immigration authorities. 97. 98. 99. 100. E.g.
