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 in the United States
Historically, over 40 states or territories, including colonies before the Declaration of Independence, have at some time given at least some aliens voting rights in some or all elections. For example, in 1875, the Supreme Court in "Minor v. Happersett" noted that "citizenship has not in all cases been made a condition precedent to the enjoyment of the right of suffrage. Thus, in Missouri, persons of foreign birth, who have declared their intention to become citizens of the United States, may under certain circumstances vote."
