Do I need an appointment to obtain the final stamp for my Non-O visa after the 30-day consideration period?

The user applied for a Non-O visa and received a 30-day stamp while waiting for the final approval. They are unsure whether they need to make another appointment or can return to the same counter without one. Responses indicate that after the 30 days, the user should simply return to the appropriate counter with their passport and required documents, as appointments for this stage are not necessary.
