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.
Election day
Election day or polling day is the day on which general elections are held. In many countries, general elections are always held on a Saturday or Sunday, to enable as many voters as possible to participate; while in other countries elections are always held on a weekday. However, some countries, or regions within a country, which hold elections on a weekday declare election day a public holiday. Countries which permit absentee ballots, early ballots or postal votes to be cast by mail before the election avoid the problem altogether by enabling voters to vote on a day that is more convenient to them.
