What is a requirement to vote in federal elections?

To vote in federal elections, an individual must be a legal resident of the state in which they wish to vote. This residency requirement ensures that voters have a genuine connection to the community and local issues that their elected officials will address. Each state has its own laws regarding voter registration and residency, which must be adhered to for a person to be eligible to participate in elections.

The other options provided do not accurately reflect the requirements for voting in federal elections. For instance, while age is a consideration, the minimum age to vote is actually 18 years old, not 21. Additionally, property ownership and educational qualifications like having a college degree are not required to be eligible to vote in federal elections. This means that anyone who meets the age and residency criteria may register to vote, regardless of their financial or educational status.
