What are the education and profession requirements for US Green Card participants?

You either need to have "high school education or its equivalent" or "two years experience in an occupation requiring two years of experience or training". You should NOT include any documentation confirming any of this with your application under the Green Card Lottery. Further details are covered below:

Education: You will need to show high school education as being equivalent to twelve years of education in the US up to secondary level. It may be that in some countries you can show that less than twelve years of education is equivalent to high school level education in the US. You may need to provide documentation that proves your education is equivalent to the minimum high school education standard expected if you win.

OR

Work Experience: You will need to be in a skilled occupation to be able to apply for the US Green Card Lottery. The requirement is to show at least two years of training or experience, within the past five years, in an occupation that qualifies for a Green Card. The Department of Labor's O*Net system is used to determine whether the occupation is at a sufficiently high level for the Green Card Lottery.

If you cannot meet these requirements, you should NOT submit an entry to the Diversity Visa program!
