In theory EVERY USCIS Local Field Office may perform same day oath. Legally, the Court can formally exert exclusive jurisdiction to administer the oath to EVERY applicant for naturalization within its geographic jurisdiction with limited exceptions. I don't know the specific arrangements at that Office.
