Birth tourism
Some countries do not allow their citizens to renounce their citizenship or only if the citizenship was acquired by birth there to non-citizen parents. In Argentina, Brazil, Ecuador, Peru, and Uruguay, voting is compulsory for citizens. In Bolivia, Brazil, Chile, Colombia, Cuba, Guatemala, Paraguay, and Venezuela, military service is mandatory.
Electoral roll
Electoral rolls, under various names, are used in, for example, the United States, United Kingdom, Australia and New Zealand, but not all jurisdictions require voter registration as a prerequisite for voting, such as in the State of North Dakota in the United States. Most jurisdictions close updating of electoral rolls some period, commonly 14 or 28 days, before an election, but some American jurisdictions allow registration at the same time as attending a polling station to vote, and Australia closes the rolls 7 days after an election is called, rather than with reference to election day.
