US Immigration from Haiti

I applied for my mom and currently waiting for an interview. I read somewhere on NVC that after my mom's interview she can request for a visa for my brother. Can someone explain this to me and what are the chances of it being approved. It's been almost 2 years since I applied for her. The process is so slow I just want both of them here already. Btw I did add my brothers name on the application.

Hello , anyone know how long NVC take to review a form I 864 rejected please. Form I 130 spouse.

Is there any updates on when the U.S embassy will resume visa appointments???

Good evening everyone, I'm in the process of preparing my I-129F to petition for my Fianc from Haiti. I'm just having trouble with the certain forms and documents that are required to be sent with it. Is the form I-864 required to be sent along with the application? Or will that be needed at the time of the interview? Any tips and advice that you're able to offer will be greatly appreciated as well!

Hello guys! My fiance s passport about to get expired on july 2021, and our case i ve been ready since mars 2020 and we re still waiting the embassy to open to have our interview so do you think that is a good motif to request for emergency interview? Any advice please and thank you
