The foreign government to which an ambassador is assigned must first approve the person. In some cases, the foreign government might reverse its approval by declaring the diplomat a ''persona non grata'', i.e. an unacceptable person. This kind of declaration usually results in recalling the ambassador to their home nation. In accordance with the Congress of Vienna of 1815 and the 1961 [[Vienna Convention on Diplomatic Relations]], the ambassador and embassy staff are granted diplomatic immunity and personal safety while living abroad.<ref>{{cite web | url = https://careers.state.gov/work/foreign-service/officer | title = Foreign Service Officer | work = United States Department of State | quote = Purpose of Ambassador | access-date = 10 December 2019 | archive-date = 10 December 2019 | archive-url = https://web.archive.org/web/20191210042547/https://careers.state.gov/work/foreign-service/officer/ | url-status = live }}</ref><ref name="a1" >{{cite web | url = https://2009-2017.state.gov/r/pa/ei/rls/dos/221.htm | title = Major State Department Publications | work = United States Department of State | quote = Purpose of Ambassador | access-date = 22 May 2019 | archive-date = 2 August 2018 | archive-url = https://web.archive.org/web/20180802043202/https://2009-2017.state.gov/r/pa/ei/rls/dos/221.htm | url-status = live }}</ref>

=== Protect citizens ===
Due to the advent of modern technologies, today's world is a much smaller place in relative terms. With this in mind, it is considered important that the nations of the world have at least a small staff living in foreign capitals in order to aid travelers and visitors from their home nation. As an officer of the foreign service, an ambassador is expected to protect the citizens of their home country in the host country.<ref name="a2" >{{Cite web|url=https://careers.state.gov/work/foreign-service/officer/|title=Foreign Service Officer|first=David|last=Nicinski|access-date=10 December 2019|archive-date=10 December 2019|archive-url=https://web.archive.org/web/20191210042547/https://careers.state.gov/work/foreign-service/officer/|url-status=live}}</ref><ref name="a1" />

=== Support prosperity ===
Another result of the increase in foreign travel is the growth of trade between nations. For most countries, the national economy is now part of the [[global economy]]. This means increased opportunities to sell and trade with other nations. When two nations are conducting a trade, it is usually advantageous to both parties to have an ambassador and perhaps a small staff living in the other land, where they act as an intermediary between cooperative businesses.<ref name="a2" /><ref name="a1" />

=== Work for peace ===
One of the cornerstones of foreign diplomatic missions is to work for peace. This task can grow into a fight against international terrorism, the drug trade, international bribery, and human trafficking. Ambassadors help stop these acts, helping people across the globe. These activities are important and sensitive and are usually carried out in coordination with the Defense Ministry of the state and the head of the nation.<ref name="a2" /><ref name="a1" />
