There are four amendments to the U.S. Constitution about who can vote. Describe one of them.

What does this answer mean?

Four amendments to the Constitution expanded who can vote, and you only need to describe one. USCIS accepts: citizens eighteen and older can vote; you don't have to pay a poll tax to vote; any citizen can vote, women and men; or a male citizen of any race can vote.

Each answer matches an amendment. The 15th Amendment, ratified in 1870 after the Civil War, says the right to vote can't be denied because of race or color. The 19th Amendment, ratified in 1920, says it can't be denied because of sex, which gave women across the country the right to vote. The 24th Amendment, ratified in 1964, bans poll taxes, which were fees some states charged to vote in federal elections. The 26th Amendment, ratified in 1971, says citizens 18 or older can't be denied the vote because of age.

Notice that every one of these protects citizens. Voting in federal elections is a right of U.S. citizens.

At the interview, an easy answer is "Citizens eighteen and older can vote."
