How long did it take you from the time you submitted it to the time you were confirmed for the interview? I know it takes a lot of time, so I’m curious how long it took you. My sister will also have an EB-3 interview soon and we study information about it from time to time. We recently watched a video about it https://www.youtube.com/watch?v=f0zUkZnYf7Y. A lot of useful information from John Dorer from EB3.Work and former consular officer Tiffney Johnson. I think this information will help you find answers to your questions.
