No. You can complete the application by yourself on the official DV Lottery website. The process is free and easy to complete. You can however ask an immigration lawyer to clear any doubts in advance or to confirm application due dates. At the moment of applying, you’ll need your personal information, family details, education/work information and a digital photo. Keep in mind that if you get selected, you’ll need to attend an interview and take all relevant documentation with you to back up what you entered on the online application. The process is the same for everyone around the world, don’t trust anyone with promises of a guaranteed win or privileged draft spot.
