If you mean the job you are (or have) performed is at SVP 6 to 7 then it is not just the length of time worked that is an issue. You don't mention what job zone your work is classified as - that is important too. The rules say this:-
"
High School Education: A high school education means successful completion of a formal course of elementary and secondary education comparable to completion of a 12-year course in the United States.
Work Experience: If you are qualifying with work experience, you must have two years of experience in the last five years, in an occupation which, by U.S. Department of Labor definitions, requires at least two years of training or experience that is designated as Job Zone 4 or 5, classified in a Specific Vocational Preparation (SVP) rating of 7.0 or higher.
The U.S. Department of Labor provides information on job duties, knowledge and skills, education and training, and other occupational characteristics on their website
http://www.onetonline.org/. The O*Net online database groups work experience into five "job zones." While many occupations are listed, only certain specified occupations qualify for the Diversity Visa Program."
You can qualify on education basis alone, or on work experience alone. Work experience route is harder because it is somewhat subjective. However, given the time you have worked (after the apprenticeship) is only 1 year in the last 5 years AND that that job (as you are now saying) is not a SVP of 7.0 or above then I am starting to fear that you will not qualify by work experience.
So - are you qualified by the education route?
