US Immigration from Nigeria

Hello,please i want to schedule for my medical Examination at Abuja Nigeria, i want to know how much Vaccination cost,i visted the website of the hospital, i saw the price for the medical Examination and other test but the price for Vaccinations isn't there..please does anyone have an idea how much it would cost? And secondly i want to know if my Husband would be allowed to go in with me for the interview if he is around during my interview. Thank you

Please i need help. When my mum applied for i130 in 2018 i was single. I got married 2020. And my approval notice cane January 2021. Please do i declear my marriage? because there is no category for LPR for married children. Please advise

My Nigerian Spouse just received his visa but no packet or none of his info was returned?! I m reading he will need to present the sealed packet that should have been given to him when he goes through customs, is this normal for him to not receive this? Will he still be able to come? Help!

I submitted all the required documents at NVC they checked and accepted everything but they said i should get a joint sponsor. My questions is can i still be scheduled for an interview even if i dont provide it at NVC stage. I was thinking i should just take it along to the interview.

Please is there anyone that was given a form to provide a joint sponsor and a recent tax record?

please I would like to know what am to submit to the GSS document collection center in Lagos state,Nigeria.

Am I to submit either the W2 form or Transcript or strictly the transcript.
I think submitting the transcript might take almost or over a month since the Tax filing begins this week.

please I need urgent clarification from anyone who has been in this before,thank you!
