Winning the DV Lottery while residing outside of the U. S.:
To initiate the process for obtaining an immigrant visa, you are required to complete Form DS-260 on the Consular Electronic Application Center website, provide corroborating documents for yourself and the family members who will be relocating to the U.S., schedule and attend an interview at a U.S. Consulate, receive a Visa Packet, undergo an interview with a U.S. Customs and Border Protection officer upon entry to the U.S., and provide an American address where documents will be received.
The process is complex and needs to be meticulous. All documents must be strictly completed in English. Any errors in paperwork or failure to meet the deadline or interview may result in losing the lottery win and a Green Card denial.
It is highly recommended you seek assistance of a licensed immigration attorney to safeguard individuals from denial of becoming a U.S. resident.
