A-number and USCIS account umber are two very different things. All immigrants have an A-number. Only those who have previously filed a petition ONLINE have a USCIS account number. Many of us never filed a petition online because the petitions were paper filings only back then, so we don't have any such numbers. You will get one after you have submitted your online filing, so you just skip that question when you fill out your petition. 
 

You speak of a "window" in regards to renewing her greencard and also mention "eligibility to apply for the N-400" (if so, she can't possibly have a 10-year greencard at this point). You make it sound like she needs to file for ROC, not a renewal. Please confirm as that would change people's answers DRASTICALLY. If it is indeed an i-751 and not an i-90, then she is not eligible to file her N-400 until around this time NEXT year. So that would explain why she can't start the filing of the N-400.

Can you ask the clinic for a copy of the medical results to see what the issue is. I got a copy of the full medical exam/results (including x-ray results) sent to me from the clinic the same day they sent the original to the embassy. That would likely shed some light on what's going on. 

I was going to say the same thing, OP should post the entire rejection letter (remove all personal info).
Also, what does the DS-3025 say? Was it marked complete? OP needs to check their copy just in case. It could've been missed.

It would be VERY helpful if you could post the exact language of the 221G instead of just your interpretation of it. We might be able to figure out what it means.

Greencards are for living in the US. Your parents haven't lived in the US at all, not even once since becoming greencard holders in 2018, from what I understand. That's ~6 years of being greencard holders and getting away with not living in the US, they have been lucky. They should give up their greencards and then you can file for them again once they have actually decided they are going to live in the US.

While greencard holders can generally stay out of the US for up to 1 year at a time, the border control agent can absolutely report them after being outside for only 6 months if it seems they are not actually living in the US (and clearly they don't and never did, they can see their entry/exits dates in the system and know these ppl don't live in the US and therefore shouldn't have greencards).

Personally I waited until my then USC fiance received the email from the embassy that described what to do next. That happened a little while after the status changed to "ready".

We have seen British people getting RFEs for not translating their ENGLISH marriage or birth certificates. Resend the certificate and write a very short explanation that it IS in English - If the English part is on a second page I would also make sure to make an extra copy of that particular page and add that as well, on top of the certified one. In my country we don't have birth certificates for instance, so I made very sure to put post-its on the "extract from the population register" where it said this is the ONLY "birth certificates" we have in Sweden. It's USCIS after all, they often need things explained to them in a very clear way. 

Why would you send a second one? Several people, including me, told you to wait. It still hasn't even been that long. You're making it so much harder than it needs to be. You can't handle US immigration like this, or you'll drive yourself mad. Every part of this journey is slooow.

It's only been 8 business days, give them at least two weeks to cash the check. If rejected, you just resend it after fixing whatever the issue is.

Payment amount incorrect is usually a generic thing all reject letters state along with the actual issue. I for instance had an issue printing the form and it ended up cut off at the bottom without me noticing, and my rejection letter also stated payment amount incorrect along with "outdated form" or similar wording because the form was messed up. Nothing wrong with my payment. I sent back the same stuff but with a new printed form and the i-765 was accepted just fine. 

If you can't find anything wrong with your filing, resend it and include printouts from USCIS' website and highlight the part where it says i-765 fee is waived when filed together with a i-485. Also include a copy of the i-485 receipt notice. 

The sticky tabs I added to the bottom of the pages weren't removed, they were still there when I saw my file on the IOs desk at my N-400 interview. They seem to be able to scan everything with the tabs still there, if the tabs are at the bottom and not on the side. So those sticky tabs shouldn't add any extra work at all. That's likely why they tell you to use sticky tabs on their own website. 

Personally, I brought my USC husband's passport and birth certificate. I also brought the interview letter, my greencard, driver license, all of my passports (two expired and one valid), a few more docs proving a bonafide marriage (3 year rule) and the entire tax return that we had filed just a couple of days prior (no transcript available yet). 

Before the interview started, the IO wanted to see my ID/DL, my greencard and two of my three passports (the valid/newest and the oldest with the K-1 visa in it). 
After the interview she scanned my tax return into their system. 

So in my case nothing was needed from my husband, and no extra evidence either (I had already uploaded a ton in my online account and been through ROC a year prior, so that probably helped). 

If you owe taxes from previous years, make sure to bring your payment plan. We didn't owe but I have seen others having issues for forgetting to bring it.
