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 expatriates to vote in their country of origin
The right of expatriates to vote in elections in their country of origin varies depending on the legislation of an expatriate’s country of origin. Some countries (such as France) grant their expatriate citizens unlimited voting rights, identical to those of citizens living in their home country. Other countries allow expatriate citizens to vote only for a certain number of years after leaving the country, after which they are no longer eligible to vote (e.g. 15 years for the UK and 25 years for Germany). Other countries reserve the right vote solely to citizens living in that country, thereby stripping expatriate citizens of their voting rights once they leave their home country (such as Ireland, with extremely limited exceptions).
