Which right is only for United States citizens?

The right to vote in federal elections is a fundamental right that is exclusively granted to United States citizens. This right is outlined in various amendments, notably the 15th, 19th, 24th, and 26th amendments, which collectively protect against voting discrimination based on race, sex, or age for those who are 18 years and older.

While the right to free speech, the right to bear arms, and the right to a speedy trial are also important protections, they are not limited only to citizens. Free speech rights apply to anyone within the country, including non-citizens. Similarly, the right to bear arms and the right to a speedy trial are rights that can be claimed by anyone present in the United States, regardless of their citizenship status. Therefore, the voting right is distinct as it is specifically reserved for citizens, making it the correct choice in this context.
