applies a dual nationality restriction: the rule does not apply automatically if the child also has another nationality.14 12. Most countries provide that the child of a national born abroad has access to the nationality of the parent. However, there are a number of exceptions. In five states there is a generational restriction on the transmission of nationality to children born abroad: the nationality of the parent is not attributed or recognised automatically if the parent was also born abroad (unless this would render the child stateless).15 However, the legislation of some of these states allows the nationality of the parent to be acquired by registration. In seven other states, the attribution or recognition of the nationality of the parent for the child born abroad is subject to the child’s registration at a consulate or to an application for the parent’s nationality, except in cases where the child would otherwise be stateless.16 Identified promising practice Luxembourg has an unconditional double ius soli provision: the nationality is attributed to the child of foreign parents if at least one of the parents was also born in Luxembourg regardless of whether the child’s statelessness is established or not. 3. A specific nationality determination procedure for a child born on the country’s territory if it is in doubt 13. If the nationality of a child born on a country’s territory is in doubt, establishing a specific nationality determination procedure, implemented by trained staff within the competent authorities, can be considered advisable. The staff concerned should possess the legal and language knowledge necessary to identify and record the nationality status. Identified promising practice Sweden has a nationality determination procedure applicable to children born on its territory and whose nationality is uncertain. The Swedish Migration Agency begins its assessment of whether a person is stateless by investigating whether that person has a citizenship. The focus of this investigation is on the countries with which they have relevant ties (country of birth, parents’ citizenship, previous habitual residence). 14. North Macedonia. 15.
