Who can vote in federal elections, run for federal office, and serve on a jury in the United States?

Why this is the answer

Three things are reserved for U.S. citizens: voting in federal elections, running for federal office and serving on a jury. Lawful permanent residents share most other rights and responsibilities, such as paying taxes and registering for the Selective Service, but not these three. They come with citizenship, which is part of what naturalization gives you. Any of the three official wordings is accepted. Memory hook: vote, run, jury: citizens only.
