Persona non grata
Foreign person whose stay is prohibited by a country's government
In diplomacy, a persona non grata (also abbreviated to PNG) (Latin: "person not welcome", plural: personae non gratae) is a foreign diplomat who is asked by the host country to be recalled to their home country. If the person is not recalled as requested, the host state may refuse to recognize the person concerned as a member of the diplomatic mission (including the removal of diplomatic immunity). A host country may declare persona non grata status for any member of a diplomatic staff at any time without any explanation.
