Which of the following groups is protected under the refugee definition in the INA?

The correct choice highlights a specific category of individuals who qualify for protection under the refugee definition established in the Immigration and Nationality Act (INA). This definition explicitly includes those who experience persecution or have a well-founded fear of persecution due to race, religion, nationality, membership in a particular social group, or political opinion. This protective measure is crucial as it aligns with international law and human rights standards, ensuring that individuals who suffer from severe forms of discrimination or threats to their safety due to these characteristics can seek asylum in the United States.

In contrast, the other options do not align with the criteria for refugee status. An individual from a foreign country alone does not qualify for refugee status unless they meet the persecution criteria. Furthermore, individuals seeking to visit another country are not necessarily facing persecution and thus do not fit the definition of a refugee. Likewise, people with valid work permits in the U.S. may have the legal right to work but do not experience persecution based on the stated grounds required for refugee status.
