Direct answer: Eligibility to vote varies by country, election type, and local rules. In most democracies, voting is generally limited to residents who meet age, citizenship, and registration requirements; some places allow non- citizens to vote only in specific local elections, and others require voters to be registered in advance. Always check the specific election and jurisdiction you’re asking about to confirm eligibility, registration deadlines, and any identification requirements. If you’d like, share the country or region and the type of election (national, regional, local) you’re curious about, and I can provide a tailored overview of who can vote there and how to verify your eligibility.
