US Immigration from Morocco

Hey, all. My fianc and I received our NOA2 mid-June. It's taking 60-90 days for shipping to DOS/NVC. My fianc (beneficiary) was living in Turkey, so we had Ankara as embassy for interview. My fianc has since moved back to his home country of Morocco, and we need to update the location to the consulate in Casablanca. I keep looking online (USCIS website, groups I'm in, etc.) but am unsure of when or where is the most appropriate time/entity to notify of this change. I did a PI and of course as NVC has not received it yet, they said they cannot locate the case and will "work with USCIS" (it's been two weeks and heard nothing back). Is anyone able to assist with how to go about changing this to minimize delay? We really don't want it going to the Ankara embassy and then taking longer to transfer. Thanks in advance.

It states on the NVC website: "If a visa is not available because of statutory limits on the number of visas, NVC cannot schedule your interview." Does anyone know the number of visas granted to each country by the U.S.? Or a website that might have that information?

Coming from RAK to EWR, with a K1 visa, does anyone know if a transit visa is needed, i.e. from Marrakech to Newark, with layover in CDG, LIS or YYZ

form i-129f requires listing all addresses for the past 5 years with no elaboration. I could not find this question answered elsewhere on this portal (the best I've seen is advice to INCLUDE short term college addresses):

I've had the same permanent address (parents home) until last year, but 4 unique college dorms/apts in between, and my new permanent address, all in the last 5 years.

How do I list these? Do I have to repeat my parents' home over and over between each college dorm address? this will require 11 addresses. I can't think of a way that is both honest and not annoyingly excessive. Can I just list my parents home once, for 4 years until my new permanent home, and just include the college addresses double counting for some of the time, or is that unwise?

my address history is:

college dorm 1: spring 2020

home: summer 2020

college apt 1: spring 2021

home: summer 2021

college apt 2: fall 2021 - spring 2022

home: summer 2022

college apt 2 again: fall 2022 - spring 2023

home: summer 2023

college dorm 4: fall 2023

home: early 2024

new permanent home: 2024-now

K1 visa was refused, pending submission of the original divorce decree. Problem is the original was sent to them, but they rejected it. What in God's name do they need?
