Define the term “alien” in the context of U.S. immigration law.

• A. A person with U.S. citizenship
• B. Any person who is not a U.S. citizen or national
• C. A foreign visitor on a temporary visa
• D. A naturalized citizen

Answer: (B)

In the context of U.S. immigration law, the term “alien” is defined as any person who is not a U.S. citizen or national. This definition encompasses individuals who may be in the United States legally or illegally, including those who hold various types of visas, individuals seeking asylum, and those who do not have any legal status. Recognizing this definition is essential, as it lays the foundation for understanding further legal classifications and rights regarding immigration, status adjustments, and enforcement actions. The other options represent different categories of individuals but do not accurately reflect the broad definition of an alien in U.S. immigration law. For instance, U.S. citizens, whether by birth or naturalization, are distinctly identified from aliens, and temporary visitors with visas are a subset of aliens rather than a definition of the term itself.
