A) employment as a first responder INCORRECT Employment as a first responder, such as a police officer or firefighter, does not universally require U.S. citizenship. While many local and state agencies may have their own requirements, federal law does not mandate citizenship for all first responder positions. Some jurisdictions allow lawful permanent residents or other eligible non-citizens to serve in these roles, especially in volunteer capacities. Therefore, this option is not a definitive requirement of citizenship.
B) membership in the military INCORRECT Membership in the U.S. military is not exclusively limited to U.S. citizens. Non-citizens who are lawful permanent residents can enlist in the armed forces, and in some cases, non-citizens with certain visas may be eligible under specific programs. The military has historically recruited non-citizens, offering a path to citizenship through service. Thus, while citizenship may be a goal for some service members, it is not a prerequisite for enlistment.
C) high school graduation INCORRECT High school graduation is not a requirement of U.S. citizenship. In fact, many non-citizens, including undocumented immigrants, attend and graduate from U.S. high schools. Education is a right extended to all children regardless of immigration status, as affirmed by the Supreme Court in Plyler v. Doe (1982). Therefore, graduating from high school is not tied to citizenship status.
D) federal jury service CORRECT Federal jury service is a civic duty that requires U.S. citizenship. According to the Jury Selection and Service Act of 1968, only U.S. citizens are eligible to serve on federal grand and petit juries. This requirement ensures that those who decide the fate of defendants in federal courts are part of the sovereign citizenry. Serving on a jury is both a right and a responsibility of citizenship, allowing individuals to participate directly in the judicial branch of government. This distinguishes it from other activities that may be open to non-citizens.
