Each year the Department of State provides 50,000 immigrant visas ("green cards") for people from selected countries in its Diversity Visa Lottery program (DV-2015).
Entries for the DV-2015 DV program must be submitted electronically at www.dvlottery.state.gov beginning at noon, Eastern Daylight Time (EDT) (GMT-4), Tuesday, October 1, 2013. This year, the deadline for the DV lottery applications is noon, Eastern Daylight Time (EDT) (GMT-4), Saturday, November 2, 2013, so if you are in a nonimmigrant status or would like to immigrate to the United States, you may want to try your luck.

According to the the Department of State, if you submit more than one entry you will be disqualified.
