It also provides practical advice and legal assistance to help persons obtain identity and nationality documentation, which eliminates many risks of statelessness. In the Balkans, for example, some 50,000 members of the Roma, Ashkali and Egyptian minorities lack personal documentation. Many are refugees or have been internally displaced and socially excluded. On a large scale, UNHCR engages in citizenship campaigns, supporting Governments which have taken steps to resolve a stateless situation.
