Thanks man, i really appreciate.

She will be your Sponsor but need a Joint Sponsor to meet the financial requirements.

Hey Guys, am among the March filers and i got my NOA2 Approval 17th of September, 2018. Am so happy for this long awaiting letter. I pray the next letter comes before my wife gives birth, because she will be due in December or January.
I wish you guys waiting for the same letter all the best. Thanks VJ for everything.

Did you guys file for a K1 visa or CR1? Because if you did file K1, that is the wrong visa. You cannot be married and file for K1, you must file for CR1 if you are married.

Your chances for getting a B2 visa are slim to none, so a birth in Nigeria is the only way for you to be  with her during that time.  Good luck.

She can transmit citizenship to the child by registering the child's birth(CRBA)and obtaining a US passport for the child along with supporting docs at the USEM in Lagos. 

To be clear, CRBA is Certificate of Birth Abroad, at the US Embassy in Lagos.  If a US Citizen's child is born abroad, that process must be completed and a US passport applied for and received before the child can travel.  Having the child born in the US, avoids that process, but the more time you spend together in person, the better, in terms of a successful spouse visa process.

Honestly, better she has the baby in Nigeria if that's what she feels more comfortable doing, and if that's what she really wants.
Besides, there's always the possibility of your tourist visa being denied.
Another thing to consider if she is in Nigeria now, (not sure by your original post) is also the possibility of her being denied boarding on the flight depending on how far along she is in her pregnancy by the time your visa comes through (if approved)
