I recently received a notice for oath ceremony, but it had my maiden name on it when I requested to have name change during the interview process. So I made an appointment to see an immigration officer and she stated that name change request was done internally and should have the correct name when I receive the certificate of naturalization.

The Notice for the Oath Ceremony must have your current name on it as your new name is only effective after the Oath Ceremony.

The officer at your natz interview usually prints up a sheet with all the certificate information for your review and approval prior to completing the interview; did they do this?

The immigration officer did not print or allowed me to review any information.

The new name should be correct on your certificate. Congratulations.
