Get ready to cast your vote in the US presidential election! To exercise your fundamental right, you must meet certain eligibility criteria. According to a comprehensive guide, you need to be at least 18 years old on or before election day, a US citizen (natural-born or naturalized), and a resident of the state where you're registered to vote. Some states also have specific residency requirements. Additionally, individuals declared mentally incompetent by a court may not be eligible to vote, while voting rights for convicted felons vary by state.
