I arrived at the Garden City DO at approximately 10:15 this morning. My interview was scheduled for 11:25, so I decided to try my luck and see if the security guards would allow me to get in early. They politely told me to come back at 11:00, so I dropped my fiancee off at Bloomingdale's at the Roosevelt Field Mall and drove back to the parking lot at 711 Stewart Avenue. I should mention that there is plenty of free parking available, so don't worry about where you can leave your vehicle.
I have read somewhere from another person's experience that if you want a faster Judicial Oath Ceremony, you should take matters into your own hands. What this person did was to call up most of the Judges (District Court?), who can perform such matter, & to ask/request if s/he could perform the service for her. That was how she got hers done quicker than waiting for the normal time frame it takes this type of ceremony to be scheduled. Depending on your DO, it could be a very long time (5-13 months).
