Final answer:
The statement means that anyone born or naturalized in the United States is considered a citizen. Citizenship is important because it grants legal rights and comes with responsibilities.
Step-by-step explanation:
The statement "All persons born or naturalized in the United States are citizens of the United States" is a quotation from the 14th Amendment to the United States Constitution. This amendment defines citizenship and grants equal protection under the law to all citizens. It means that anyone who is born in the United States or has gone through the process of naturalization is considered a citizen of the United States. Citizenship is important because it grants individuals certain legal rights, such as the right to vote, the right to work, and the right to receive government benefits. It also comes with responsibilities, such as obeying the law and paying taxes.
