Which of the following is NOT a right that is only for United States citizens?

The right to free speech is a fundamental right that is guaranteed to all individuals under the First Amendment of the United States Constitution, regardless of their citizenship status. This means that citizens and non-citizens alike have the right to express themselves freely.

In contrast, the rights to vote in federal elections and to run for federal office are privileges that are specifically reserved for U.S. citizens. These rights reflect the democratic participation that is afforded solely to those who are members of the nation. Similarly, while the right to a fair trial is a vital legal protection available to everyone in the U.S. (including non-citizens), it is not restricted only to citizens in the same way that voting and running for office are. However, the context in which these rights apply can vary depending on the legal status of the individual.

Thus, free speech stands out as the option that is available to all individuals, making it the correct answer.
