US Immigration from Canada

I currently got laid off from my Canada job that I was working remotely for while living in America. I qualify for unemployment with the Canadian government. I am wondering if I would be able to take that money? Would this count negatively towards me during the interview? To note: I have a lot of savings, no debts, and live with my husband who works full time.

thank you

I recently received a job offer and they explained that they need to complete Foreign National paperwork which could take 2-3 months to process. Anyone else experience this?

The form asks for 2" by 2" photos. To me it sounds like they want passport style photos, but I have never heard of passport photos being square... can anyone help me out :)?

I've read the guides, searched the forum, and looked at the Canada consulate reviews, so I think this is fine, but I just want to check:

I'm putting our initial I-129F packet together now and it's recommended to mail a copy of the "exact" packet to your fianc e. We have every page we're submitting (including scans of all the signed pages) in a shared Dropbox anyway (and we've kept extra wet copies/extra passport photos in case the packet gets lost) and I'd rather not waste the paper, printer ink, paper clips, post-it notes, and cost to ship an "exact" copy of the packet to my fianc e. I also don't see the point in making another packet for myself since I can just print the contents out again if needed.

Is it fine if my fianc e just reviews the packet contents on her own/brings her own printouts to the interview? Does she even need to bring a copy of every single page of the I-129F to the interview, or just the evidence (and of course, what she's required to bring to the interview)? Honestly from the reviews, it doesn't seem like any of the I-129F content is ever asked for.

TIA for reading

Previous Situation:

My son is 19 in F2A category. I have a GC, applying for a GC for him. Everything got approved at NVC and is on hold due to proclamation. My I864 got approved. we are just waiting for interview. Who knows if the proclamation will be extended after Dec 31.

Current:

He and his girlfriend want to do the K1 route starting January if nothing moves on my petition with him. Girlfriend will move in with me in January from Sacramento and start the K1 process. She will start working right away (hopefully) but who knows if she will meet the minimum requirement for I134. Can his and/or my assets be counted toward the I134? We will all be living together. How and when will joint sponsorship play into the K1 process?

Thanks
