Frustrating: Which country do you come from? was rejected. Why?
"Which" would mean "de qual"
Poor English grammar (verbatim would be better).
The translation to this is 'What country are you from?'. That seems a bit off. i would have guessed that it meant 'whose father are you?' or 'who is your father' (who's your daddy? :P)
pais = fathers/parents; paÍs = country
