Hi
@Grizzly toad looks like your new to the forum, welcome. It's worthwhile reading the previous pages (At least half way through the back pages) cause you'll learn a lot about the green card process and most of your questions will be already answered.
First things first: Submit your DS260 form as soon as you can, but at the same time, don't make rushed errors. This is because one you submit it, youll have to ask the U.S. consular centre (KCC) to unlock it and that takes time. ALSO the results from the 2023 DV lottery will be released next month in May so they'll be lots of others submitting forms next month, so get in quick as the form crashes a lot. Also, if you don't receive you passport embassy stamp by September 30th, 2022, that's it! You've missed out officially. Opportunity gone. That's currently 5 months away. And there's a whole bunch of people queueing waiting in line in front of you to secure interviews ( to receive appointment time/day in what's called a 2NL letter). There are people in the same region as you (OC) who have already submitted their DS260 months ago, who are genuinely worried they might not get their interview and visa processed by the Sept 30 deadline.
Secondly, to explain some of the forum shorthand. When you see someone write their case number as e.g. OC3XXX, they are saying their case number is in the OC3000s, it could be OC3150 or it could be OC3832, etc. They share their case number like this so its more private as Case numbers are a way you interact with KCC, medical exam, embassy and so people don't want to broadcast their case number to identify themselves too closely. So if you see OC12XX that just means their case number is somewhere between OC1200 and OC1299.
Thirdly, take everyone's posts on this forum as their opinion or personal experience, nothing you read here is gospel or official advice. It's just people helping people. There are however some very experienced posters/moderators here who are extremely helpful and come with so much experience (like Sm1smom and Britsimon). Follow their guidance as it's reliable, BUT don't hassle them by repeating questions if you don't like their response. if they respond to a forum question of yours that's awesome (don't @ them, its not necessary and it spams them), if you don't like their response or disagree - that's fine, do whatever you would like to do during the diversity Visa process as ultimately it's your life's opportunity and the U.S. embassy decides.
Good luck, enjoy the forum, I've personally learned a lot. Thanks
