H.R. 4300 was a bill to radically increase annual immigration numbers by removing or increasing limits in most immigration categories. As well, H.R. 4300 created the diversity visa lottery. Traditional American immigration had averaged around 250,000 a year until the 1980s when it dramatically rose to around 500,000. Largely as a result of H.R. 4300, annual legal immigration has risen to around 1,000,000 (one million) a year.
