The green card lottery (Diversity Immigrant Visa Program) makes available 50,000 permanent resident visas annually, drawn from random selection among all entries to persons who meet strict eligibility requirements from countries with low rates of immigration to the United States. To be eligible to participate in the Green Card Lottery, you must meet (1) the education and training requirements (either a high school education or its equivalent, or two years of work experience within the past five years in an occupation requiring at least two years of training or experience to perform); and (2) you must be a native of a qualifying country.
