Each case is different, may have different Administrative Processing needs, etc. We had another member who interviewed in Manila last week and their case status didn't change to Issued until 8 calendar days after the interview. Then if it's being shipped home instead of being picked up at the VAC, you have to add in the transit time for LBC.
You cannot make the CFO appointment without the visa number so you will have to wait until you get the passport back
When we made Jaycel's appointment, we had to wait until the following week but that was because CFO only operates Mon-Thurs and that week there was a national holiday on Thursday. The calendar for CFO is usually pretty good until a day or two before the day.
Congrats on getting the approval!! Keep checking the case number status on CEAC for when it's issued and you should have it within a few days of that status update
