A/HRC/7/23 page 24 82. States are urged to ratify or accede to all relevant international conventions, including the International Convention on the Elimination of All Forms of Racial Discrimination and the Convention on the Reduction of Statelessness, to ensure that nationality legislation is consistent with such standards and to fully conform to international obligations. 83. UNHCR and OHCHR should undertake a study to reveal further the dimensions of the statelessness problems of minorities globally. This should include, to the extent possible, the collection and analysis of statistical data disaggregated on the basis of gender, ethnic, linguistic and religious criteria. 84. States must register all children and issue birth certificates immediately after birth in a non-discriminatory manner. Where birth registration certificates do not confer nationality, States should allow for procedures for citizenship determination by an independent body shortly after birth. 85. States must grant nationality to children born on their territory if the child would otherwise be stateless. In this case, the immigration status of parents should be irrelevant. 86. States are urged to allow dual or multiple nationality. 87. States are encouraged to facilitate the acquisition of citizenship through naturalization procedures or permanent residency to persons lawfully resident in the country for a period commensurate with their having created established social, economic and community ties in the State. It is recommended that the period be no longer than 10 years. 88. State requirements for the granting of citizenship should be reasonable and not be overly burdensome for individuals. 89. States should facilitate full access to identity documentation in a non-discriminatory manner. In any determination that supporting documents are fraudulent, the burden should be upon the State to prove falsity and such determination should be subject to judicial review and appeal. Registration should take into account the particular circumstances of persons belonging to minorities, including lack of birth registration when ancestors arrived in the territory of the State. Registration costs should be minimal, and registration offices should be physically accessible to all. Registration forms should be in all national languages and in the languages spoken by large minority populations. 90. States should conduct information campaigns on the right to citizenship and necessary procedures to obtain recognition of this right, in a language and a form accessible to all. Minority groups should be directly involved and represented in relevant administrative structures. Mobile campaigns are often a good means of addressing existing documentation problems and reaching rural areas. -----
