US Immigration from Canada

Greetings good people!

The abbreviated version of our story: I entered the US (from Canada) in 2012 on a K1 visa. We've been happily married since. Yay! Around the start of Covid we moved to Canada for family reasons and originally did not intend to return to the US in a full-time capacity... at least for the foreseeable future. Well, things have changed of course and now we're looking to return. My wife (US citizen by birth) is moving back next week for a new job and I'm hanging back here until we can secure an IR-1.

I do have a green card, but as per everything I read online, because I've been a full-time resident outside of the US for almost 3 years, it's considered as abandoned. Now, there's been nothing official from me or USCIS about said abandonment. I did find out recently that there is a form to formally notify that I'm not longer a resident, so I'll be filling that out immediately. I am kicking myself a bit for not knowing that before, but here we are.

Question is, does anyone know if we can just immediately apply for CR-1 after submitting the I-407 (green card abandonment) or if they may reject due to my having only just abandoned my green card?

Also, before anybody asks, yes we have thought about the SB-1, but it seems pretty clear that I have to have intended to return to the US all along and were unable, which is clearly not the case.

We are waiting to hear back from an immigration attorney but I figured I'd post here to see if anyone has any insight.

Cheers!

I have my N400 interview later this week, but I also have my I-751 pending still. A lot of people have commented about having a combo interview, but my notice doesn't say anything about it being a combo interview, nor has the status changed online. It still says 'I-751 Case has been received'.

Has anyone else had experience with a non-combo N400 interview?

I'm not seeing a December thread, so here we go I-751 December filers!

I was hoping to file in November, but was away and didn't mail it soon enough. So, mailed my application today, expected delivery Monday!

Here we go again!!

My bank in Canada is requesting my ITIN, I am a permanent resident now and I don't think I was ever issued one (I got my SSN 2 weeks after entering the U.S.)

I am super confused on the difference between the two and online all I can find is that if I have a SSN already I can't get apply for a ITIN nor do I need one? anyone know?

thanks

I am wondering if I need to fill out form AR-11 (Alien's change of address) to notify the USCIS that I moved to a different house even though I stay over at the previous house once in a while. I still receive mail at the previous house as well. Would this complicate anything?
