The DV Lottery has been fully automated, and would-be immigrants from eligible countries may apply online only. You will not be mailed a letter or emailed a notice alerting you that you “won” or that your entry was not accepted. The only way to find out whether you were successful is to use the electronic Entrant Status Check at www.dvlottery.state.gov/ESC.
Entries to the DV Lottery are accepted each autumn (usually for about a month from October to November, but check the DV Lottery website to make sure).
Starting in early May of the year after you apply, you will be able to use Entrant Status Check to learn whether or not you were randomly chosen from the entrants from your country for the opportunity to apply for an immigrant visa.
Do not delay in checking your status, because if you are a lottery winner you will need to act fast in order to get all the necessary information together for submitting your green card application. All winners must apply for and be issued their DV visas before the following October. Also, every year there are more “winning entries” than there are actual visas, so you must act fast to benefit from the lottery.
