US Immigration from Ghana

My father (Petioner) filed for me and my siblings and our priority date is 18th December 2015. Two of my siblings received their welcome letter in 2019 but the rest of us have not received our welcome letters. Per the june 2021 visa (16th March 2016) bulletin our priority date is earlier than the cutt off date of the date of filing for submission of documents at NVC. Should I contact Nvc for the welcome letter?

Our I-130 was approved on may18, 2021 and then I received and email On May20, 2021 that the case had been sent to Department of state. Can someone tell me what that means and what I need to prepare for?
thanks in advance

My priority date is 18th December 2015 and in the current visa bulletin for the date for filing is 16th March 2016.. will Nvc contact me soon to submit my documents

I filed I-751 to remove condition based on K1 with a divorce decree in May 2020. My receipt Num starts with LIN.........

I and my spouse had interview on I-485 and was approved and we got divorced 2yrs later.
I got RFE based on bonafide relationship. I submitted the RFE and my spouse wrote and affidavit describing our togetherness and things didn t work out they way we planned.
today I got a mail saying my case was transferred to another uscis office and that office has jurisdiction over my case.

1. Is this a gud sign?

2. Will I have to go for interview ?

3 Is the office the local uscis in my county?

4 how long before I am approved or be called for interview ?

i will appreciate any experienced answers.

Sent form I-130 and all related documents to NVC on April 18th 2019.

Application was approved and case opened Nov. 4th 2019 ( NVC informed me that the documents are being sent to Ghana Embassy in Accra where his interview will be scheduled)

In February I received an email stating his Interview was scheduled for April 9th 2020.

In March 2020 I received another email stating his Interview was rescheduled to August 19th 2020 due to COVID.

In June another email stating his was received saying IM and all other visas have been suspended until further notice.

I kept enquiring about when a new interview would be schedled and finally in March 2021 a new interview was scheduled for May 5th 2021.

He sent a new Police certificate and new medicals because they already expired.

His interview day arrived and he was granted an Immigrant Visa which he would collect at DHL.

His account of the interview process was rather long and don't want to bore all the readers so let me know if anyone's parent has an upcoming interview and is interested in knowing some of the questions asked and the new covid protocols etc.
