Your colleagues? 10 people from your work may know you, rest of the Ameircans might still think you are an illegal immigrant, and a possible terrorist. I am not talking about what legal papers you have, I am talking about what Americans think you to be. For sure, everyone knows you an immigrant, one who didn't have any thing to eat back in his poor country and trying make a good living here, as they feel pity at you, dude.
