persona non grata 불청객

Persona non grata (Latin, plural: personae non gratae), literally meaning "an unwelcome person", is a legal term used in diplomacy that indicates a proscription against a person entering the country. It is the most serious form of censure which one country can apply to foreign diplomats, who are otherwise protected by diplomatic immunity from arrest and other normal kinds of prosecution. The antonym of persona non grata is persona grata.
