Far-aim
So who wrote the FAR-AIM? If it "clearly states", someone in the US must speak proper English.
But how all those Americans can meet the requirement baffles me. Of course I assume you refer to all the Mexicans, French speaking Canadiens, Portugese speaking Brazilians etc. Or are you talking about people from the US? It appears your message may not have conveyed the intended message. If I were to assume that you are talking about people from the US when you talk about Americans, I would interpret your post differently. Please be clear in your communications so that we avoid misunderstandings.
But your message is not clear to me as a non-native English speaker.
Want to pick nits some more???
