Just to point out that what I bolded above is not correct. If someone is selected and they have submitted a DS260 and their number is current, they will get an interview. There is no pre-sorting done - only a consular official in an interview can determine whether or not the applicant is qualified for a DV. In any case the eligibility criteria do not have to be met at the time of entry, only by interview - and there is no way to prove work eligibility on the entry form anyway. So no one is selected out on eligibility criteria at any stage of the process before interview. So in this case the applicant if selected would go through the entire process, pay for medicals etc and the interview fee and only then get officially told what they knew all along, that they are not eligible. The only disqualification right after entry /selection would be for duplicate entries, and if they pick that up the entry itself does not get announced as selected (this is why DV case numbers are not all consecutive).
