US Immigration from Nigeria

I'm an American citizen. Anyone knows where to sign or get this form notorized before submission. I will be unable to appear for the interview, wanting to know which passport agent will handle this issue as it states in the form

Please I need someone that processed his or her green by February this year to update me if they have received it. I have processed my green card since February this year and I am yet to receive it. This waiting is tiring ooo

Hello. I'm a USC and I petitioned for my husband who is a Nigerian citizen. He was not approved at his interview back in 2018 and we were in Administrative Processing since then. I reached out to my congressman's office and they were told that the case had been returned to USCIS for recommendation to revoke on July 2019. I checked everyday and NVC would always tell me they didn't have our case back from the Embassy yet.

Until one day I checked and they told me they had the case back since October 2020...then they kept telling me that they were doing their checks on it before sending to USCIS.

Well just recently they told me that the case has been sent back on April 13.

My question now is, how long should we wait to hear something from USCIS? Do they send me a letter or text or email letting me know that they received the case back?

Hope this is okay, I just wanted to start a new topic for May 2021 fillers. I just applied for my mum and it says it's been processed at the Nabraska service center

Hi,

My Status:

1. F4 Category

2. Documentary Qualified and awaiting interview invitation.

3. I have a fiancee and I wish to settle in marriage with her.

Question:

I wish to settle with my fiancee in marriage but I am afraid of the separation when my visa is eventually granted.

What advice do you have for me on how to fast-track her application once my F4 application is successful?

I am very worried about this.

Please help with advice. Thanks
