Section 203(c) of the Immigration and Nationality Act (INA) provides for a class of immigrants known as “diversity immigrants” from countries with historically low rates of immigration to the United States. A limited number of visas are available each fiscal year through the Diversity Visa (DV) Program, which is popularly known as the Green Card lottery or DV lottery.
The online registration period for the 2021 Diversity Visa Program (DV-2021) opened on October 2, 2019, and closed on November 5, 2019.
It is not possible for you to submit an application now that the registration period is closed. Do not believe any individual, company or website that tells you otherwise.
