1. Agrement
Agrement is the formal agreement by a receiving state to accept a named individual as head of a diplomatic mission. As a part of diplomatic courtesy, before a state appoints a new chief of mission to represent it in another state, it must be first ascertained whether the appointee is acceptable to the receiving state.
Though it is unusual for an appointee to be refused it occasionally happens. If the receiving state acquiesces the proposed person, it grants the agrement.

Asylum, in diplomacy, means the giving of refuge in two senses: first, within the extraterritorial grounds of an embassy; second, when a state allows someone to live within its borders, out of reach of the authority of a second state from which the person seeks protection.
When a political refugee seeks shelter either in the territory of a foreign state or in the compound of the premises of the diplomatic mission, he/she is said to have sought asylum. If protection is granted to the refugee, such a person becomes immune from the process of law of the state to which he/she belongs.
