Question 97 of 128
What amendment says all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are U.S. citizens?
Official USCIS answers
- 14th Amendment
Why this is the answer
After the Civil War, the Constitution needed a clear rule for national citizenship, especially for formerly enslaved people. The 14th Amendment gives U.S. citizenship to people born or naturalized in the United States and subject to its jurisdiction. That is why it is the official answer for this question.
💡 Memory tip: Remember: 14th Amendment = citizenship by birth or naturalization.
