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.
Human rights in Belgium
Eighteen is the age when the right to vote is attained. Universal suffrage was enacted in 1893. Belgium was the first country in the world to introduce compulsory voting, in 1892 for men and 1949 for women. Eligible voters who fail to cast a ballot "face a moderate fine or, if they fail to vote in at least four elections, they can lose the right to vote for 10 years."
