Which category of person can a state refuse entry to?

• A. Sexy star
• B. Refugee
• C. Persona non grata
• D. Political Prisoner

Answer: (C)

States have sovereignty over who may enter, and they can declare someone persona non grata, meaning they are unwelcome and can be denied entry or expelled. This status is a recognized tool in diplomacy used to remove or bar individuals who offend the host country. Among the options, this is the category that directly authorizes entry refusal as a formal designation. Refugees have protections under international law, so states cannot simply bar them at will and must follow asylum procedures and non-refoulement rules. Political prisoners aren’t a recognized immigration category that grants entry denial, and “sexy star” isn’t a real category. So the best fit is persona non grata.
