who were the foreigners..Africans, immigrants..foreign representatives..
Africans were considered property by the Founders.
No Africans immigrated, they were forced. If the founders considered them property..it is impossible to be NBC. Read the books the founders had..all so far point to the Founders not wanting Africans (property) in the government.
They could not naturalize.
Jus Quiritium
You need to look at the former institutions of bondage themselves and not the origins of the people under it. There were freemen who were African. There were British who were bound.
