Adjustment of Status - I-485

Goodmorning friends,so my wife and i had our interview on the 29th which to my best knowledge i believe went well.The IO was a nice man and he made things so easy all through for my wife and I.It took just 35minutes in all.he requested for our IDs and ny passport then he started asking my wife basic questions like her dads name,moms name,date of birth e.t.c. he asked me the same questions and the last time i came into the U.S.A.he then went onto the yes/no from the i485.after that,he told us everything is good and that our baby is a very great proof of our bonafide marriage but he asked if we had some other evidences to add to it which we already prepared for.I handed over our lease,creditcard statement,bjs cards,joint car insurance,joint medical insurance,joint dental insurance,my wives 401k with me being the beneficiary,electricty bill,water bill.he said everything looks good but he printed out a RFE for a form G325A saying it was missing in our application.He told us to mail it to him so he can approve us.he then said he would love to listen to our love story.i did a little and my wife also continued from how she proposed and all.After that,he went ahead into talking to us about removing conditions on the green card and when i am elegible to apply for my citizenship.

i mailed the G325A form sameday and it was delivered to the front desk the following day which was on tuesday.however,i would love to know how long it might take for the I.O to work on my case or get me approved because i have been reading it takes more time when you are being served with a RFE.thanks and Godbless
