I applied marriage base application 3 years terms, I went for interview with my wife and daughter, officer came asked me is she my wife and I said "Yes , officer took my my wife inside (told me i have to ask some question to her ) I waited 25 minutes in lobby , when my wife came back I quickly asked what officer questioned you , she replied its just regular question , like when did we mate , what date we got married along with some other personal question, my wife told me same question when i switch my status from F1 to i485 Green card.
so , I went inside officer asked me civic question and i passed than she asked my lots of question about when we married, and if I have green card 10 YEARS , i told her yes and handed over , she asked if i came for interview I751, I told officer NO , where did i filled up application , I told i was home with my wfie and she signed than she gave me 3 paper some correction and in the n400 form also we filed together i751 for removal condition green card at home , officer also took witness sign another USCIS officer, for i did filled out form at home with my wife, LOL after all that she handed over me as usual paper
