"Most countries’ legislations lay down a nationality requirement. However, a tendency is emerging to grant local political rights to long-standing foreign residents, in accordance with the Council of Europe Convention on the Participation of Foreigners in Public Life at Local Level. It is accordingly recommended that the right to vote in local elections be granted after a certain period of residence. Furthermore, under the European integration process European citizens have been granted the right to vote and stand for election in municipal and European Parliament elections in their EU member state of residence. The nationality criterion can, moreover, sometimes cause problems if a state withholds citizenship from persons who have been settled in its territory for several generations, for instance on linguistic grounds. Furthermore, under the European Convention on Nationality persons holding dual nationality must have the same electoral rights as other nationals."
