Make sure you meet all the detailed qualifications before you apply!
The U.S. Department of State has announced that the Diversity Lottery for Fiscal Year 2015 will be open for applications beginning October 1, 2013. The Diversity Lottery targets immigrants from countries with traditionally low rates of immigration, and 50,000 visas will be available via the 2015 lottery.
As in previous years, there is no cost to register for the Diversity Lottery, but as highlighted by LexisNexis, there are many pitfalls involved with the Program. Make sure you meet all of the requirements prior to applying. The FAQs at the State Department instructions are especially useful.
