The Diversity Immigrant Visa program (often called the DV-1 or "green-card lottery") was created by the Immigration Act of 1990. It allocates a fixed number of immigrant visas — roughly fifty thousand annually — to applicants from countries that have sent relatively few immigrants to the United States over the prior years. Applicants must meet basic education or work-experience requirements and pass security and health screening.
The program is widely used in many African, Eastern European, and other regions with limited family- or employment-based immigration paths to the United States. Selection is by random lottery among eligible entrants.
Reform debates include whether to eliminate the program, replace it with merit-weighted criteria, redirect the visas to backlog reduction or employment-based use, or to retain it while tightening eligibility and security checks.
