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.
Right of foreigners to vote
The 1992 Maastricht Treaty imposed reciprocity inside the European Union concerning voting rights in local elections; this already existed for the European elections. In several European states, the public debate on the right of foreigners to vote was therefore renewed, as some foreign residents had the right to vote (European foreign residents) while others, non-Europeans, did not. As a result of this debate, Luxembourg, Lithuania, Slovenia and Belgium extended the right to vote, in different manners, to all foreign residents (which was already the case in Sweden, Denmark, Finland and Netherlands).
