You're assuming alot there. You have no idea whether the packet was in English ONLY, or that they had no knowledge of the English language at all. If they were coming here to learn the English language, why would a college send them packets in English ONLY and not provide appropriate instructions through an interpretor for them to follow? You're not a social worker are you?
Look, it's pretty clear that even the FBI figured out what was happening right off the bat ~ which is pretty unusual for them.
