US Immigration from Canada

I've been waiting since May 2023 for my replacement GC. Today is the first day I can file for the I-751. USCIS agent that gave me the stamp in person told me to call the office if I still haven't received my card. But I called and they said they can't do anything.... What exactly am I supposed to do now? I can't file for I-751 without the card.. right?

From interview to approved to VOH how many days is normal to wait? I had my interview on September 12th and was verbally approved, it changed to application received the same day, checked again and it has an updated date of September 16 but still says application received. When should that change to approved? Almost everyone else who had that interview date has had their visa issued.

I am a US Citizen living in Canada as PR, with my Canadian citizen husband, and we have applied for his green card. I will be moving back to the US in a couple of months and he will stay in Canada until he is hopefully approved. Can I start moving my household items back before actually moving back, will I have issues at border? My husband will probably travel with me and we will use a trailer, it will just be easier for me as I can take a load back now and not pay for everything to be moved for me. I would like to move everything now but I am guessing moving his stuff with mine would be a hard no TIA!

I checked the case status of our K-1 Visa on CEAC and it said that the case is now Ready. Do I wait for an interview notification or should I schedule an interview appointment right away?

Looking for advice. It is seems like every USCIS conversation I have online with an agent using the Chat feature gives inconsistent information for a case. Some agents give a detailed history of the offices the case is transferred to. Others say they cannot see that information. Most recently - I will have an agent same it is in Nebraska since Aug 16 and then another say it went to TX Aug 26, and then today they said latest update is that it was transferred to Nebraska Aug 16 and with an officer there.

This is a June 27, 2023 PD - something feels off. My mother's was approved, all the June 2023 PDs I know have have had an action on their case. My mother's is sitting in limbo in at NVC while we wait for my dads which is just sitting in processing since 2023.

Has anyone had success reaching out to the officer using the online inbox feature? Or other ways? Has anyone else felt the same runaround/inconsistent information from the Chat Feature on the USCIS website? It is un-nerving how they are giving different information. Any suggestions on how to get a REAL update on this case? It should have been adjudicated by now. All other mother/father cases in this blog are typically pushed through the USCIS stage only a day or so apart, longest i've seen is a couple weeks. I am almost at a month now between when Mother's was approved.
