How old do citizens have to be to vote for President?

Why This Matters

This is a straightforward question, but it is important because it relates to one of your most valuable rights as a future citizen: the right to vote. The USCIS officer asks this question to make sure you know the minimum age required to vote for the President of the United States. The answer is simple, you must be eighteen years old or older.

The voting age was not always eighteen. Before 1971, you had to be twenty-one years old to vote in most states. During the Vietnam War, many young Americans argued that if they were old enough to be drafted into the military at eighteen, they should be old enough to vote. This led to the 26th Amendment, which lowered the voting age to eighteen across the entire country. It was one of the fastest amendments ever ratified, passing in just over two months.

This piece of history shows how Americans have fought to make their democracy more inclusive. As a new citizen, once you are eighteen or older, you have the right to vote in every election, local, state, and federal. This is one of the most powerful ways you can participate in shaping the future of your community and country.

Key Facts

• Citizens must be eighteen years old or older to vote for President
• The 26th Amendment, ratified in 1971, lowered the voting age from twenty-one to eighteen
• The voting age applies to all elections, not just presidential ones
• You must also be registered to vote in your state before you can cast a ballot

Common Mistakes

• Saying "twenty-one", that was the old voting age before the 26th Amendment
• Forgetting to say "and older", the answer is eighteen and older, not just eighteen
• Confusing the voting age with the age to run for office, you must be at least twenty-five to serve in the House and thirty to serve in the Senate

Study Tip

Connect the number eighteen to voting by thinking: "At eighteen, I can vote." This is a simple, one-fact question. If you remember the number eighteen, you have the answer. Pair it with the 26th Amendment if you want extra confidence, "the 26th Amendment set the voting age at eighteen."
