Another fake visa lottery

Yet another fake visa lottery scam arrives. A reader received a lengthy email announcing that:

"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."

It goes on to announce that:

"U.S. Government helps you with the accommodation and offers you Health Insurance (Freedom HSA Direct Individual Health insurance for 1 year), Dwelling(Apartment in any city you prefer, 1 bedroom for 3 months ), a guaranteed job(in the field that you are are currently qualified so you can start working even from the first week you arrive in the United States and get paid as U.S citizen. ) and education (for U.S. Students or Higher Education through EducationUSA. It includes transfer to a U.S college or University so you can continue your educational study.

What? Sounds amazing, don't you think?

However there's a catch. A big catch:

"United States Permanent Resident Card Granted! - Waiting for payment of processing fee $879
Processing fees Included. Total $879
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."

And the final clue that this is a scam?

"The fees must be paid using Western Union money transfer and will be processed by the U.S. embassy in the United Kingdom."
