region, no single country may receive more than seven percent of the available DVs in any one year. Visas are allocated to nationals of countries with historically lower rates of U.S. immigration. Nationals of countries who have sent more than 50,000 immigrants to the United States over the past five years are not eligible to apply for the Diversity Visa program. The Department of State implemented the electronic registration system beginning with DV-2005 in order to make the DV process more efficient and secure. The Department utilizes special technology and other means to identify those who commit fraud for the purposes of illegal immigration or those who submit multiple entries. So if you really want to be among the lucky winners avoid multiple registrations.
