<P> One famous case is that of Mehran Karimi Nasseri, an expelled Iranian who lived in Charles de Gaulle Airport in France for approximately 18 years after he was denied entry to the country . (The 1994 French film Tombés du ciel and the 2004 American film The Terminal are fictional stories inspired by his experiences .) </P> <P> Another case is that of Zahra Kamalfar, an Iranian who lived in Sheremetyevo International Airport near Moscow for many months before receiving refugee status in Canada . </P> <P> Countries that restrict multiple nationality often require immigrants who apply for naturalisation to obtain official documentation from their countries of origin proving that they are no longer citizens . In others, including Taiwan, the documentation must be provided prior to the granting of citizenship . During the period between the renunciation / cancellation of the prior citizenship and the granting of the new citizenship by naturalization, the applicant may be officially stateless . (In two cases in Taiwan, Pakistani immigrants applied for naturalization and renounced their Pakistani citizenship . In the interim, the decisions to permit their naturalization as citizens of Taiwan were reversed, leaving them stateless .) </P> <P> There are a large number of stateless permanent residents in Brunei . Most of these residents have lived on Bruneian soil for generations, but Bruneian nationality is governed by the policy of jus sanguinis; the right to hold it comes from blood ties . The government of Brunei has made obtaining citizenship possible, albeit difficult, for stateless people who have inhabited Brunei for many generations . Requirements include rigorous tests in Malay culture, customs, and language . Stateless permanent residents of Brunei are given an International Certificate of Identity, which allows them to travel overseas . The majority of Brunei's Chinese and Indians are permanent residents . </P>
