After you have completed the steps on the Diversity Visa Process on travel.state.gov, including submitting the required immigrant visa application form (DS-260), you may receive an email from the Kentucky Consular Center (KCC) to let you know that an interview has been scheduled for you.  The email will instruct you to log into the Entrant Status Check on the Electronic Diversity Visa (E-DV) website, using your DV entry confirmation number, to view the date, time and location of your interview.

You can learn more about the interview process on travel.state.gov and via this instructional video.

At interview, you must bring the original versions of all documents submitted to KCC, copies of those documents, and two 5cm x 5cm photographs. In addition, you must bring sufficient money (in U.S. dollars or Armenian dram) to pay the required fees at the cashier. Cash notes must be in good condition, not worn or damaged, or the cashier will be unable to accept them. Please review the section on Supporting Documents at Diversity Visa Process on travel.state.gov.

What happens if you forget to bring something on this list?  The consular officer will not be able to complete the processing of your visa. You will have to gather the missing items and provide them to the embassy, and may have to come for additional interviews.  Failure to bring all items on the above list can delay visa issuance.
