Diversity Visa Lottery winners are never notified by e-mail.
Don't Transfer Money
Never transfer money to anyone who e-mails you claiming that you have won the Diversity Visa lottery or been selected for a Green Card.
Beware Fraudulent Websites
Some websites and emails try to mislead customers and members of the public into thinking they are official U.S. government websites. Any website address that does not end in ".gov" should be considered suspect.
The only official information about the DV program is found on U.S. government websites ending in ".gov," such as http://travel.state.gov or http://www.dvlottery.state.gov. The only official way to apply for the DV program is directly through the official U.S. Department of State website during the specified and limited registration period.
Check your Lottery Status Online
Entrants to the DV program must check their status of their DV lottery entry online at http://www.dvlottery.state.gov.
