US Immigration from Australia

So my wife and I have just got back from our AoS initial interview in SLC today. Everything seemed to be going well, IO was nice and had some friendly discussion. Asked my wife a few questions about me and had a quick look at my passport, vaccination documents but didn't ask for much else.

We were then informed that he couldn't see the I-129F petition in our files as well as the Medical exam documentation I took prior to my K1 visa interview. They said I was likely to receive a RFE for another medical or possibly secondary interview if he couldn't chase up the documents.

Has anyone else gone through a similar experience? We were baffled that the files we submitted seemed to be missing from their system

Hi all,

I was hoping to get some feedback or advice on my status and plans!

A quick explainer:

Wife is USC, I am Australian and we are both UK Residents.
I-130 submitted on May-21. No Response yet.
Consular interview location selected at London.
Wife starts new job in US around August 22 (I will accompany to help set up).

Now after my wife moves to the US, we will not have a real reason to stay in the UK as I'll quit my job and our lease is up anyway! The only thing tying us back to the UK is the pre-selected location for the interview.

Is it feasible to change the location to another embassy/consulate? For example after I help set up in the US and with the expiration of 90 day ESTA I would prefer to fly back to Australia to be with family and try and find a quick source of temporary income.
My fear is that changing anything with the application process will result in staggering delays and pain.

My ideal scenario would be, I-130 approved within 13/14 months (May or June 22) and a consular interview in 3 months after the fact which means a quick 1 week trip back to the UK for an interview and a pint then back to Freedomland with my GC.

The threats to my plan are extra delays in i-130 processing and issues with buying a 1 way ticket to the US (as I won't know what date to fly back to the UK for the interview).

It should be noted we have an immigration lawyer, though truth be told, they do not inspire confidence.

Thanks everyone.

Just wondering, the SSN card i received with my EAD while awaiting for my 485 to be approved states that it is for work purposes only. As my 485 is approved, does this mean a NEW SSN will be sent out? Or is that my SSN now until life and a new card will come with my GC?

(Not sure if asking in the correct area) The guy who did our interview could not answer the question, so im wondering if someone else in this situation could explain how it all works from this point onwards

We have the interview this week, we were given like 2 weeks notice. Filed 485 within 1 year of medical, Am i sposed to still go get the 693 or whatever it was?
What is a must to take?
What do they ask?

Lodging i-130's for 2 unmarried minors (both under 18).

Mum is a naturalized citizen, who is a stay at home mum with no income. Step dad is US citizen by birth, working full time who has supported the family since he petitioned them to come to the US in 2011.

What would be best to petition for the kids? The biological mum with no income or the US born step dad who's working full time?

I'm assuming once it gets to the consulate stage and the affidavit of support was needed, the step dads income could be used for this?

We will be applying for expedition due to their circumstances so want this to to go the quickest and easiest way possible.

Any advice / information would be appreciated.
