I've gotten great help from everyone here, so I want to share my interview experience, in hope that it helps somewhat to those of you waiting.
Location: Skopje, Macedonia
We picked up our medical results at 7AM from the hospital, and went to the embassy at 8AM for our interview. We were the first in the list to be called, so we walked in to an empty embassy interview hall. A nice guy helped us arrange all of our documents, and soon after 10 minutes, we got called to hand out the prepared documents. The guy took our fingerprints, and asked us if we have any valid visas. At this point I also saw that he has a CSPA worksheet for me, which had all the details of when the case was sent and approved, along with the last row, saying "QUALIFIES".
After being done here, we were seated again, and waited for the interview with the consul. We got called 10 minutes after, we approached the window, and we were asked to raise our right hand, and swear to tell the truth.
Then my mom was asked only 3 questions:
1. Who's applying for your immigration petition?
2. Where does he live?
3. What does he do?
And the last question was for all of us (me, my mom and dad):
4. Have you ever committed any crime?
After this, he said, thank you, your visas have been approved and we will call you within the next two weeks to pick them up. Have a good life in the US.
No one at any time mentioned anything about my age (i'm currently 24, about to be 25. But my CSPA age is 19). The only thing that i glimpsed was the CSPA Worksheet.
Everyone at the embassy was really warm and really made you feel like there were there to help you and not cause issues.
Overall, the best possible experience we could have hoped for.
If any of the beneficiaries or derivative beneficiaries were present in the US (for example, on an F-1 student visa) at the time the petitioner died, you may be able to claim relief under 204(l):
