US Immigration from Nigeria

Hi everyone, I am a LPR and reside in the US , my mom is to visit and applied for a B1 visa last year 2023 when I had my first child based on long wait times for my country (Nigeria) her interview is this month

I am currently pregnant for baby number 2 and my obgyn wrote me a letter to submit at the embassy recommending my moms visa be granted as I would need her during this pregnancy and emphasizing how my previous pregnancy recovery was tough ,

I have some questions

1. Do you think this will help? have anyone followed this route ?

2. How do I send the documents along with other documents to the embassy?

any and all reply is welcome, thank you

Good evening! I filed my I -130 online and mailed my I-485 six months later because I was waiting on a waiver approval to attach to it. The I-130 receipt was attached to the mailed I-485 and my account shows concurrent filing. Will they adjudicate the I-485 and I-130 together? Any experiences here to share? Thank you so much!!

How long is it taking to get a interview letter once you are documentary qualified? Do the interviews occur in Abuja and Lagos? Is Abuja considered quicker?

I had my interview less than 2weeks ago. On the day of the interview I had 3 status update. I don't understand what it means. I was told I will get my letter within 10 to 15 days. Please, anyone have similar status.

My brother's F1 visa is set to expire in June. He misses his family and want to visit Lagos, and return in May (1 month before visa expiry). He has a valid I20, but we are worried his Visa might not be renewed because he switched his Course of Study from Masters(Law) to BSc (Nursing). He just wants a 3weeks visit to see his family whom he misses so much. The school says it is Ok for him to travel and return provided the visa is still valid. Pls can you advise if there is any risk he might be denied re-entry to the US.

Thank you!
