1.  To live in the US, it would be an F4 category visa.  It would take 20+ years.  Start by filing an I-130 for each sibling. 
2. To visit the US, each sibling would have to apply for a visitor visa on their US embassy web site.

November 11, 2023

As they've said above, 3 years - 90 days which would put you at November 11 2023. 

That section is for the passport photos of the beneficiary.

beneficiary's passport photos (you only need one).

Just your spouse passport photograph.

you can upload 3 years but you only need your most recent one.

My husband is Nigerian also, we just got document qualified on June 18. Our lawyer suggested that we wait until after the November election or when the travel ban gets lifted. My husband and I decided to proceed with NVC and take our chance with the interview. 
 
Keep the faith, stay positive, and make the best decision for you and your spouse. 

@Dejavudeji31...
 
PROCEED TO PAY YOUR NVC FEES!
 
Don't get the earlier communications wrong. You have a fair chance at the interview stage despite the ban. DO NOT JOKE WITH THE FEE PAYMENT. please proceed.
 
You did not get this far to quit now right? Please do the needful....
 
Best regards

We finally got a email from NVC that our petition  (1-30) is approved on the 17 of June 2020,what is the next step to do

This is what I mean. Above your uploads, you should see the documents from them 

YEah we was able to log in the account today and this is what we saw
 

There's no fee for those going K3 route. So no there's nothing you will get it's free for I-130 filers.
 
What to send with your I-130:
Form G-1145 Form I-129F Petitioners US Birth Certificate Marriage certificate of petitioner and beneficiary Divorce decree and certified translation of beneficiary (If applicable) One (1) passport photo of the petitioner and One (1) passport photo of beneficiary Copy of the Form I-797C (Notice of Action)  
 

Did you know her before you physically met? Through online or similar?   That could help your case look better.  The fact you got married without knowing eachother for longer than 2 weeks is a big red flag from a high fraud country.  
 
I would go to the Nigerian forum on this webpage to see if they have any further advise for you. 

Your wife should prepare all the necessary documents, including evidence of your one and only visit together (boarding passes, passport stamps, hotel receipts, wedding photos), and your marriage certificate, and file the I-130 as soon as possible.  It takes a least a year from filing the petition until your visa interview will be held in Nigeria, if all goes well with the petition and NVC stages.  In the year you are waiting, you need to do more visits to be together, in Nigeria, the US, or anywhere really.  Save the evidence of all those visits.  Submit the evidence of these additional visits at the NVC stage (called side-loading), and then take evidence of visits after that to the interview.  As an example, my husband and I were together for four visits before marriage and sent that evidence with the I-130 petition package.  Then we had three more visits between petition filing and submitting documents at NVC so we sent evidence of those trips to NVC.  Now we're waiting for his interview to be scheduled and he will take evidence of three more visits after the NVC stage to the interview, a total of ten visits by the time he has his interview.  So use the one year to see each other as often as you can, and submit all the evidence with the NVC package (about 7 or 8 months after I-130 petition filing), and take evidence of your visits after that to the interview (about 5 months after petition approval).  You have lots of time to do more visits.  For the Nigeria embassy, these visits are very important to increase the probability of approval.  Getting married on the first and only visit, as others have said, will most likely result in denial at the interview.  Good luck!
