Congratulations! You just won the visa lottery

Dear XYZ,

"You are one of the 50,000 winners selected by the computer random draw from the 12.1 million entries registered in the Diversity Immigrant Visa Program. The Diversity Immigrant Visa program is a United States congressionally-mandated lottery program for receiving a United States Permanent Resident Card. It is also known as the Green Card Lottery."
Maybe you or someone you know has received such an email declaring you winner in the Diversity Visa (DV) Lottery program of the U.S. government. For those who are interested in living in the U.S. this is exciting news indeed, especially if they had applied. Interestingly however, sometimes the 'winner' may not even have applied for the DV lottery.Anyway you read on and the next thing is
"Although the Diversity Visa participation was free, the law and regulations require to every diversity visa winner to pay a visa processing fee of $879. The Diversity Visa (Green Card) is guaranteed upon receiving the payment. The per person fee for each Diversity Visa is $879, payable in U.S. dollars or equivalent of your local currency. This $879 fee is the only fee a winner needs to pay throughout the entire relocation process."
