It is a scam to get you to cash their check at your bank and send money orders and money grams back to them. The check looks real and the bank that the check is drawn has a website to make you think that it is real. The letter tells you to spend a certain amount at select stores, send two money orders, and they give you a salary of a portion of the money. The letter tell you to contact them when you receive the letter and get instructions on what to do. When you contact them they first ask you if you have cashed the check, but if you haven't cashed the check then they tell you to cash the check and cal them back for instructions.
