For prior Enlisted who got commissioned already.
When are you entitled to wear the O rank and use the title after the Oath of Office and Service Agreement are completed. I am not sure if I should wait until the system is updated, and I get a new updated CAC or until I completed ODS, which could take months, prior to start using the Officer Rank and new Title in communication. But technically you are discharged as an Enlisted and re entered in the Navy and sworn in as an officer, so I am confused now.
Thank you all and good luck to new applicants.
