I am French and I live in Belgium, where there is a legal obligation to vote. Do I have to vote?
You have to vote only if you register to vote in Belgium and are put on the electoral roll. Only in that case will you be subject to equal treatment with Belgian nationals. The Belgian authorities can't automatically put you on the electoral roll on the basis of your residence if it's compulsory to vote in the country.
If I am on the electoral roll of my new country of residence and voting is compulsory there, am I obliged to vote?
