The correct statement concerning U.S. citizenship is:
Only native-born citizens can run for the office of president and vice-president.
This is true as the U.S. Constitution explicitly states that only natural-born citizens are eligible for these offices.
The other statements are incorrect:
- Family members can sponsor not only children under 21 but also spouses and other relatives of varying ages.
- Children of U.S. citizens, regardless of where they are born, can also receive citizenship; children of native-born parents are not the only ones who automatically receive it.
- Asylees and refugees typically have a one-year deadline to apply for asylum after entering the U.S., but they are eligible to apply for permanent residency (and eventually citizenship) after one year of being granted asylum. There is no strict one-year limit on when they must start the process of becoming a U.S. citizen, as it is contingent upon obtaining permanent residency first.
