A lot of the questions will be the same, its a lot of repeating. :/
For the G-325A's, it is easiest to fill them out online in Adobe, and then print out 4 copies. If a field is too small for your answer to be typed in, then do it by hand. Otherwise you spend hours writing everything 4 times.
You fill out the DS-230. You only fill out Part 1 though. Part 2 goes with you to the interview, and you sign it in front of them. You send off the completeled DS-230 along with the checklist (DS-2001) - - - do you have your police records?
Wherever it asks you for your case number, leave it blank. You don't know it yet, and that's fine.
You'll probably get the DS-230 in the mail in a few weeks, because they won't have known you already sent it in. They are assuming you're doing it the slow way now - but you're not. DO it now to save a few weeks!
Am I making sense?
And yep - use whatever form is on the embassy's webpage.
