Currently, is there some country which has diplomats born abroad and without any ancestry in its people?
I heard it is possible in United States, but is there any other country in world where it is possible?
Mrs. Albright is not an example for this question because she migrated to USA with her family when she was 11 y/o, in 1948. I'm talking about how could an adult person be a diplomat in different country.
In other words, could an American citizen or a Brazilian citizen, for example, represent any other country as its diplomat? Which countries? Would they be accepted as candidates?
EDIT - More information
In Brazil, for example, the candidate must be native Brazilian ("Ser brasileiro nato"), that is - according Brazilian constitution - a) simply born in Brazil (“jus soli”); b) born abroad, with at least one Brazilian parent (“jus sanguinis”). So, according this criteria, even the most talented diplomat in the world could not be a member of Brazilian Ministry of Foreign Affairs as a diplomat. Excepting his/her country, could he/she find another country?
