The US government awards approximately 50,000 green cards every year through what is known as the Diversity Immigrant Visa Program.

Diversity Lottery

IMPORTANT UPDATE for the 2019 Diversity Lottery: Due to a technical issue, the Diversity Lottery (DV)-2019 entry period that began on October 3, 2017, was closed.  The technical issue has since been resolved, and a new registration period will run from noon (ET) on October 18, 2017, until noon (ET) on November 22, 2017.  Entries submitted between October 3 and October 10, 2017, are not valid and have been excluded from the system.  If you submitted an entry during those dates, you will need to resubmit and such an entry will not count as a duplicate entry. 

Please click here for the notice provided by the Department of State on these changes.

Section 203(c) of the Immigration and Nationality Act (INA) provides for a class of immigrants known as “diversity immigrants,” who are individuals that immigrate from countries with historically low rates of immigration to the United States.  The DVs are distributed among six geographic regions and no single country may receive more than seven percent of the available DVs in any one year.
Eligibility is determined by country of birth and past employment or educational history. Applicants must have either a high school education or 2 years of experience within the past 5 years in a qualifying occupation.
