No, the interview is to determine if you are recommended for approval to become citizen or not. Only at the oath do you become a citizen.
Thanks, Bob. So, after interview goes well, you can request a Oath on the same day and get it approved? My interview is scheduled at 9:05 so I have some time before 12 (I saw earlier post saying that it's the cut-off time for same day oath).
Cheers
Cary.
