Not relatives. Is America such a paradise, and conditions so bad in the third world, that people give their children up to total strangers for a chance to immigrate?
What happens to the children after they sneak into the US? Will the fake parents raise them as their own, or sell them to slavers?Maybe they're already sold, before they attempt the crossing?
This business is ugly and horrible to think on...
Yes.
Probably not a stranger, though. Probably someone from their hometown; if not a blood relative, a connection by marriage or through work connections.
