Correct.
 
It’ll go to Montreal. A change of the consulate can be requested if they wish to interview in UK.

Yes, they’d have to contact NVC and request a change of consulate and attach a copy of their UK passport. 

Wahoooo!  Card being produced!!!!!!

Our interviewer was extremely laid back and it felt much more like a conversation than an interview.  She asked us for some of the documents upfront, specifically both of our passports and driving licenses.  After that she asked for all of the information we had brought which proved our relationship was legit (photos, bank statements, car titles, house deeds) she skimmed through the photos then put all of that in our file.  She also asked to see my EAD cards  She did not ask to see our birth certificates, my social security, my decree absolute or any of the details relating to my employment.  I think because they were either irrelevant OR already in the file.  That doesn't mean you won't be asked though, this was just our experience.  She asked us about how we met and also some follow up questions relating to that, she asked about the wedding, she asked each of us to tell her our birthdays (i.e. what is your partners birthday), she did the same with our place of birth.  Oh she also asked for the medical forms from when I submitted my K1.
 
In summary, providing you have a legitimate relationship and the correct documentation, you shouldn't have too much to worry about.

I’ve never had a problem getting back in to the country but be plan for a long wait, especially the first time you use it. 
 
Im sure it’s location dependant but at Seattle (SEATAC) you get put in a special line. That line moves so slowly it’s painful. Expect 20 people to take about 2hrs. It’s longer if lots of flights are landing because it’s the same line cabin crew and pilots use and they cut to the front all the time. Once you clear that line and answer basic questions, you’ll be taken in the back where another person has to do something (not sure what) before you eventually get a stamp, that second part is usually much quicker. They parole you for 1 year so in theory the next time you come through using the same AP card you don’t go through the second part of the process, if you renew your AP card you’re back to square 1.  It’s taken me between 2 and 3 hours each time I’ve flown internationally and that was during COVID (so not that busy). You’re standing the whole time, there are no bathrooms.

Thank you! I do have that but forgot to write it down, good catch! 

Recent I-94!

Well, nearly 680 days later I finally got notification that my interview was scheduled. Now waiting for the letter to let me know the dates. 

If your green card is issued after your 2nd wedding anniversary, you will get a 10 years green card and will not have to go through the Removal of Conditions process.  

Our status did the same thing when address was changed. 

No.  You must be a legal resident (Green Card holder) for 3 years minimum before you can apply for citizenship.  The time starts after your Adjustment of Status is approved.

The requirement isn't being married for 3 years.
 
The requirement is being a PR for 3 years, if married to a USC...

I just went through this process.
 
Used these covering letters (but amended the list of enclosures).  It may not all be required but when in doubt I usually just send it so put copies of the marriage cert in if you feel you need to.

GET THE LATEST COPIES OF THE FORMS FROM USCIS AS SOME OF THEM HAVE BEEN UPDATED.  OLD VERSIONS COULD BE REJECTED.

I’ve been waiting nearly 2 5 years and still don’t know when I’ll get my GC interview. You’re going to have to get comfortable being uncomfortable. One thing I’ve learned is that the seasoned contributors on this forum are rarely wrong. Take their advice.  

For those going through the same process here were my timelines:
 
Sent renewal forms (AP & EAD) - 01 Nov
 
Forms noted as received by USCIS - 04 Nov
 
Received NOA (employer accepted this as right to continue working in US) - 18 Nov
 
Received notification of approval - Dec 29th
 
Received combo card - Jan 8th (same day old card expired). 

Yes, do keep checking it.  My process sounds different to yours as @HRQX has pointed out.  So perhaps it won't be exactly the same but I think mine went from "Case Received" to "Fingerprints Received" (that happened after a biometrics appointment I had to attend but again, you may not have to do that, perhaps someone else can comment?  Then from there It went to "new card being produced/approved".  I actually created and online USCIS account where I was able to input my receipt number.  They then emailed me (and text) when there was a status change in any of my cases, which was handy.
 
Regarding adjustment of status (AOS).  My process has been straight forward enough so far, I'm adjusting from a K1 visa, meaning I married a US citizen.  I researched and filed all my paperwork without any assistance other than the good folks on this forum.  The main issue for me is the location I am filing from.  I'm in Seattle, WA which has some of the longest wait times for AOS in the country.  The wait time here is around 475 days from when the receive your case.  For the vast majority of people, that is not the case.  You can look for your local office (who I assume would handle your GC application) here.  The associated processing time estimates from VJ are listed with them.  VJ uses averages from other peoples cases to produce these stats, so they're not always on point but serve as a good guide. USCIS provide official estimates on their site too but they have a very wide range "12 - 19 months", for example.
 
Again, I'm not sure how the mechanics of your case differs from mine due to the type of visa we're on but maybe others can help with that.

I’m also in Seattle. Hopefully they’ll start scheduling people outside of their filling offices to speed up the process. 

Well VJ estimate was only 2 days out (pretty impressive) and my EAD approved today after 149 days.  So if the AOS estimates are as accurate, since I'm in Seattle:
 
Avg days to AOS interview: 475
Days already waited: 149
Days left: 326
 
GC interview should be...November 30th 2020. 🤭

I don't know the inner workings of USCIS but I imagine if you present a passport of a different nationality to the one you had your K1 visa in, that is going to bring up some questions.  Do they (USCIS) know you have two passports?  If they don't and it's brand new information I'm sure that's going to raise some flags.  If they do and you've already provided info about the second one, maybe not.  
 
So I'm not sure, but if it were me I'd take the time to get my Aussie one renewed and take that.  On face value it's a smoother and clearer story that requires less explanation and therefore is less likely to cause you hassle.
