I think the best advice is to just leave your application process as is and wait until during interview. In any case thats when the IO asks and confirms with the applicant if they want a name change or not and he can do the adjustment at that particular time. Hope it helps.
Hello everyone,
when I filed my N-400, I stated on the form that I want to change my name. However, I changed my mind and now want to keep my old name as is. Should I call the 800 number to inform about my decision, or can I simply indicate that during the interview???
