There are only two requirements:

1. You or your spouse must be a native of a country that is eligible to participate in the Diversity Visa Lottery. You may also be eligible to apply if your parent was born in a country that is eligible to participate.
2. You must have a high school diploma or the equivalent, defined in the United States as successful completion of a 12-year course of elementary and secondary education; OR you must have two years of work experience within the last five years in an occupation that requires at least two years of training or experience to perform.
   

Check to see who are NOT eligible.
