US Immigration from Taiwan

I m currently preparing for the joint guarantor. When I fill in the I-864 documents,
the following six documents are ready to be uploaded to NVC CASE. Are they correct and not missing?

1. sponsor I-864 PDF
2. sponsor w2 PDF
3. sponsor' tax return PDF
4. sponsor pay stubs PDF
5. sponsor passport PDF
6. sponsor ID PDF

In addition, apart from 2019_TaxReturn and 2 Federal incone taxy,
should the joint guarantor provide his 2019 TAX Transcript documents?

If these six documents are correct, do you upload six PDFs separately?
Or, except for I-864, a single PDF, and all the other five documents are uploaded in one PDF?

In the PART 5 column of I_864, the applicant only needs support for one beneficiary. Is the total number of 3 in HOUSEHOLD SIZE correct?

My case exceeds the time in Case Processing Times, so I am going to notify it on the website.
you can submit an outside normal processing time service request online.

But there is a Last Action Taken on Case, how do you fill it in?

Hi everyone,

Hope everyone is staying safe and healthy during this madness.

I received a status update on 8/7/2020: Interview Cancelled And Notice Ordered. However, I had my interview on 2/28/2020, and I did not receive a letter for a second interview.

EB3

PD 12/6/2018

Interview 2/28/2020

Status changed to interview was completed, and my case must be reviewed right after the interview.

My PD became current in August visa bulletin, so I gave USCIS a call on 8/6/2020 to request a case inquiry since my case is pending for more than 120 days after the interview. The agent told me I should receive a letter from USCIS by 8/25/2020. Just yesterday 8/7/2020, my case status changed to [Interview Cancelled And Notice Ordered].

I am wondering if anyone is on the same boat? Appreciate any advice or experience you would like to share.

Hello, everyone, I'm 2020 March AOS filer, my location is in southwest Houston, the ASC near my apartment already reopened on 7/13, but until today I still have not received my biometrics notification. The thing make me worry about is that I saw a lot of March filers already received their biometrics letter, I'm scared that USCIS already forgot me, what should I do now ?????
