美國政府自一九九四年推出「多元移民簽證（即綠卡）抽籤」（Diversity Immigration Visa Lottery，ＤＶ），每年提供約五萬多個名額給移民美國較少的國家人民抽籤，目前完全透過線上申請，初步由電腦隨機抽出約九萬名，經過面試會刷掉一部 分，最後約五萬多人可拿到移民簽證。
台灣亦可參加美國ＤＶ計劃，最近幾年台灣每年都有三、四百人抽中。2011-05-15 中國時報 【尹德瀚／綜合報導】
**IMPORTANT NOTICE REGARDING THE 2012 DIVERSITY LOTTERY PROGRAM**
We regret to inform you that, due to a computer programming problem, the results of the 2012 Diversity Lottery that were previously posted on this website have been voided. They were not valid and were posted in error. The results were not valid because they did not represent a fair, random selection of entrants, as required by U.S. law.
If you checked this website during the first week in May and found a notice that you had been selected for further processing or a notice that you had not been selected, that notice has been rescinded and is no longer valid.
A new selection process will be conducted based on the original entries for the 2012 program.
If you submitted a qualified entry from October 5, 2010 to November 3, 2010, your entry remains with us. It will be included in the new selection lottery. Your confirmation number to check results on this website is still valid.
We expect the results of the new selection process to be available on this website on or about July 15, 2011.
We regret any inconvenience this might have caused.
