US Immigration from Nigeria

I have already submitted my application online and received NOA1. Is it too late to submit G1145 so that I can receive texts and emails? If so, is there any other way to request text/ email notifications or am I stuck with mail? Thanks in advance.

What next after sending me RFE for medical exam? My VAWA has been approved since September 2020,waited for 3 months plus before I received medial exam RFE and I ve sent it back, almost 3 weeks now.

I finally received my NOA1!! I know it's going to take months before I hear anything about NOA2. I read somewhere that it is recommended to start collecting documents for NVC. Can someone give me a list of all the documents please?

Birth certificate

Marriage license

Police report

and what else?

I need yall opinion on this. I got an email from Lagos consulate that I need a joint sponsor despite the fact that my wife makes 52000$,43000$ and 32000$ consecutively in 2017,18 and 19. And also own a house with equity value of 80000$ when I went for my interview last two month the officer told me that everything is OK but I will need to submit my wif current tax transcripts which is 2019 transcripts. My wife is on SSA which she makes 21000$ per annum but in 2019 her SSA was not included in her tax transcripts because she didn't make enough for the irs to tax from her SSA thereby the only income that show on her transcript is just 12000$... Mere looking at her 2019 tax transcripts you will think she only makes 12000$ because her SSA benefit was not included on the transcript because Is not taxable.. Could this be the reason why the consulate ask for joint sponsor? Going further we contact our immigration attorney and got to know that the document he submitted from the appraiser is unclear.... Could this be reason for asking joint sponsor? I believe owning a house and making 32000$ for just a household is enough to sponsor a spouse.. Is hard to get a joint sponsor now due to COVID. We are just thinking of getting everything together and resend to Lagos consulate for reviewing.. Please your opinion is needed here thanks

I have a 2 years green and just sent in documents for the 10 years, the documents has been received since a month ago but thing has changed the have not contacted me or taking money from my account with the check I submitted and I so worry
