She suppose to file for you over there in US , most important let her get a immigration lawyer for your process , she have to pay you a second visit or third if possible to make your case very strong at the embassy when you are ready for your visa interview.

Ask your wife to visit this site and file i-130 for spouse visa petition and best of luck its a long process.

The process begins with action by the US Citizen.  A foreigner cannot begin the process by themselves.  Get your wife working on this.

I'm confused as to why you recommend an immigration lawyer as there have been hundreds who have successfully processed and received a visa with little or no problems from Nigeria.

Then you need to complete your profile because many of our answers are predicated on the information you supply in your profile. When we look at the left column and can't determine your timeline or your Embassy it's hard for us to give you a factual answer. If you look at the profile of others here, they have a flag for their country, so it makes it easy for us to reply as we can quickly determine your Embassy. Our answers will sometimes be tailored to a specific Embassy hence the reason for you to complete your profile.
 
So, if you could help yourself out and complete your profile that sure would help us out when we want to reply to your question with factual information.
