US Immigration from Cameroon

HELLO,

I am applying for an immigrant for my mother to come live in USA. On June 19, 2020 USCIS Approved I-130 and said that they sent my approval to NVC. On August 16 I sent an email to USCIS to check if they sent the document to NVC because i contacted NVC and they told me that they havent recieved anything. Then i sent then my I130 Receipt and they told me I need to file I-824 and click 1D on Part 2. but now i am little be confused because USCIS said that they send my information to NVC but NVC said that they dont have it. so i called USCIS A LADY said they will send it to NVC AND THAT IT TAKE 60-90 DAY.

I am just putting my experience here and see if someone has experience something like that. Why is the best thing to do in this situation

How would the beneficiary sign it if i didn't bring it with me on my trip? Would i have to email to my spouse to sign and they mail it back or could they scan it back to me?

Need help. How can someone know if NVC has received their case after being sent to NVC. Do you call NVC or u wait until you receive the welcome letter from NVC? Thanks.

What is your understanding of these 2 memos? Where do you put K1 filers? Please, take a close look.

On Feb 02/10 /2020 my husband i130 was reaffirmed by uscis. They sent me a reaffirmed notice. Stating petition was sent to Nvc for consular processing. On Feb 12,2020 , uscis online status changed to on Feb 12 NVC returned your petition to uscis for further review. If you have any questions about the petition call the NVC ( pure BS). Since Feb 10 until today 28 Jun 2020 my case is no where to be found. NVc are saying they never received it from USCIS. Uscis are say it was sent to NVC feb 10 .. I have been calling both offices back to back to no avail. Please can someone tell me what is going on. Has anyone been through this before
