Which populations of students are considered ineligible for federal student aid based on citizenship status?

The correct choice highlights that both non-U.S. citizens and undocumented students are ineligible for federal student aid due to their citizenship status. Federal student aid is primarily designed for U.S. citizens and eligible non-citizens, which includes certain categories of immigrants.

Non-U.S. citizens, such as international students, typically do not meet the criteria for federal financial aid. Moreover, undocumented students do not qualify for federal aid because they lack legal immigration status in the United States. This means they are not recognized as eligible recipients under the laws governing federal student assistance programs.

In contrast, U.S. citizens are fully eligible for federal student aid, and students with dual citizenship may also qualify if they meet the required criteria, including citizenship verification and residency requirements. Thus, the other options do not represent populations that would be ineligible for federal aid based on their citizenship status, making the correct answer focused on those specifically identified as non-citizens and undocumented students.
