Thanks for your reply.....I will continue waiting for the NOA. honestly this is just frustrating 

Our packet was delivered 2/12, check has not been cashed and no notification of receipt. 
 
I think they’re just going to take awhile and that’s that. Right now I’m just happy to be able to wake up every day next to the person that I love. ❤️

Well better get your mind right as this is just the beginning. Things are bound to frustrate you more sorry to say during this process. With a cool head and calm attitude you will be just fine!

Moved from K3 Process & Procedures to What Visa Do I Need - Family Based Immigration forum.

Your best option in this case will be to apply for a K-1 fiancé/fiancée visa. A K-1 visa requires both parties to have met at-least once in person within the last 2 years prior to applying, be legally free to marry and also be unmarried as well. If you guys marry you will not be eligible for a K-1 visa anymore and will have to do a spousal visa instead which will take roughly 12 to 14 months to complete.
 
You’ll need to wait overseas until you get your K-1 visa before moving to the U.S. Just so you also know USCIS is dangerously backlogged now nationwide with all immigration petitions experiencing delays, so you’ll also need a big dose of patience. Immigrating to the U.S. has never been a quick process so you’ll need to bear that in mind.
 
Again you can’t use a visit visa to come get married in the U.S. that’s why there’s a K-1 visa which will allow you to come get married and adjust your status here to lawful permanent residency. No consular officer will issue you a visa for that reason. You can also immigrate with your daughter as a K-2 dependent.

I agree that a K-1 seems like your best bet.
 
Also - have  you ever applied for a B-2 visitor visa?  Unfortunately, as a Nigerian male living abroad, you will likely have challenges getting one.

Do you have a visitor visa?  Do you realize that it's immigration fraud to use a visitor visa to enter the US and immigrate to the US?  
 
Both options that you presented includes you using a visitor visa.  It's not that easy to get a visitor visa when you are married to a US citizen and want to come live in the US.  
 
Why Option 1 will not work:  You don't have a visitor visa.  It's immigration fraud to use a visitor visa to enter the US and "legalize your stay."  
 
Why Option 2 will not work: You don't have a visitor visa.  It's immigration fraud to use a visitor visa to enter the US and adjust status.
 
There is NO WAY to avoid being separated.  You can not avoid the K-1 by using a visitor visa to immigrate to the US.  
 
Your two real choices are the K-1 or the CR-1 spousal visa.
