US Immigration from Canada

My PD is June 25th, 2023 for my standalone I-130 for my Canadian husband (I am a U.S. citizen). I have never been under active review, no one has touched my case since they received it in June of 2023.

I reached out to my congressman a month ago, and they reached out to USCIS and got a canned response back.

Now they have moved on to July cases and never have touched mine, despite it being a straightforward case. No criminal record, I was born in the US, plenty of in-person visits and interactions with my Husband both in the US and Canada.

So:
Do I reach out to my congressman again?
Do I reach out to my senator now?
Will reaching out hurt my case/processing times with USCIS?
Do I wait reach out after 15.5 months have passed in mid October?

Any advice or assurance would be appreciated, I just want to be with my Husband and the stress about not hearing anything yet is really effecting my mental health. TYIA

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?
