A normal working day (I came 3 times on weekdays for 3 questions, the situation is the same)
There will be 20 people in the queue in front of you. All windows seem to be working.
You will have to wait 2-3 hours.
Yes, based on simple mathematics, it turns out that the average capacity of the department is about 10 people per hour.
Keep this in mind when planning your visit.
