US Immigration from Kazakhstan

Hi, everyone! An odd thing just happened to us at the NVC stage. I finished uploading all the financial support info + civil docs on August 26. Today is September 2, and I already received 3 messages in the CEAC portal requesting updated documents (2019 transcript, birth certificate, marriage certificate). I was under the impression that NVC usually takes 1-2 months to review and request documents, and then you have to wait another 1-2 months for an answer again. I have not requested an expedite, though our priority date is February 2019 we were unfortunately delayed by my joint sponsor's tax filing situation. Anyway...

1. Although I uploaded my joint sponsor's 2017-18 taxes + his extension filing for 2019, they need his 2019 transcript. Ok, BUT in the CEAC portal, it's showing that they've already accepted all of my joint sponsor's documents. Do they just want me to submit the transcript by the time the interview takes place? Or will they not move forward to scheduling an interview until I've submitted it?

2. I'm more confused by their requests to re-upload my husband's birth certificate and our marriage certificate. They wrote: "We are unable to accept this document as uploaded without all sides of every page. Please replace this document in its entirety and/or with all stamps visible." The original documents are only one-sided, however. There aren't any stamps on the back. Should I upload the blank back sides, anyway? I'm not sure what else I can do.

Hi Everyone,

I became a US citizen last year and was planning to bring my mother to US. Nobody knew everything got complicated since Pandemic has occurred that results to increasing prices for petitions. Anyways, I do not really know where to start, I tried to get consultation from Immigration Attorney but they charge $200/hour which I think ridiculous. Could you tell me in short what petitions I have to fill out and which order to send them out to USCIS. Any advice will be appreciated.
