I would never recommend seeking a South American resident, this akin to men who marry some Philapina and find out the bad consequences. There are many Mex and Central American descent females in the US. Many are quite approachable and are practical and sensible about relationships and marriage. Middle class Latina’s from some South American country are both ignorant of basic US culture and are very entitled and classist. I know who literally married the cleaning lady in his office, A nice looking young woman who, he says, is nothing but kind and she definitely does not want to import her family or believe her husband should damage their family finances, they have one child now and want two moor as finances permit, by acting as private foreign aid agency.
On the Hot/Crazy matrix, sounds like a unicorn.
