How is a Mission different to an Embassy?

Answer 1

A "mission" is a more comprehensive term that includes:

embassies (the principal form of representation to a foreign country, usually headed by an ambassador, else by a chargé d'affaires ad interim)

consulates (and consulates general, a grander sort, usually in a larger city) headed by a "consul" or consul general (not to be confused with the person who handles consular affairs such as visas and passports) in an embassy

high commissions and deputy high commissions, which are exactly the same as the above two, but which are the representative offices of other Commonwealth states within the British Commonwealth

representative offices ("missions") to international organizations, such as the UN

"legations", a lesser sort of mission. The last time I was in one was in 1965, the US mission to Bulgaria in Sofia. Soon after it became an embassy. I don't know if any exist anyomore, anywhere in the world.

There are also the offices of "honorary consuls" who are often expatriates, sometimes citizens of the host country, who wave the flag, handle publicity, and often assist with consular affairs (visas, commercial and shipping documentation) on behalf of a country with which they have personal or commercial ties. I do not think that this category necessarily qualifies as a "mission".

What kind of Mission are we talking about, Catholic Mission?
The embassy's job is help foreign citizens immigrate to the USA!
Also their mission is to keep good relations between the two countries. Like USA and Mexico!
