all online, I think right after they stopped doing in person. Mid October 2024. I was shocked how quick it went. But presumably depends how many they are processing at the time and what documents need to be checked.
The new rules modify the length of your second extension, not the exemption stamp. So, you'll still get a 30 day stamp upon entry. What's changed is if you try to extend it, then you may only get a 7 day extension.
EDIT: I'm assuming this will be your second visa exempt entry into the kingdom, but that info wasn't in initial post.
