I petitioned for my wife and stepson (same time).  During the NVC process i uploaded form i864 (above the poverty line and only document required by NVC ).   It is the email I received from the embassy for the interview of my STEPSON that  has confused me.
Under the documents marked as required for my stepson's specific case they are asking to bring to the interview a photocopy of the signed form i864( which I have) and i864A.  I meet the income requirements very comfortably and I am not using anyone else to sponsor him.  Is this a mistake? 

Hello all,

In April of 2018 I submitted forms I-130 and I-130A for my wife and my stepchild.  They both have tourist visas from before and have come to visit every other month for a few days and during the summer for a month or so.  I am wondering what would happen if she was to find out that she is pregnant while vacationing here.   How would that affect the application process if we were to decide for her to stay and have the baby here?  Would i have to cancel the application and start a change of status application?  Will I lose the money already submitted for the first application?  

Thanks in advance.
