I'm telling you my personal experience of getting a social card. I chose this branch because it has a live queue from the opening.
Today (06/07.23) I arrived at 6:40 and signed up for the paper list at the entrance to the building, I was at number 36 (yesterday I arrived at 8:45 and there were already more than 100 people in the queue, according to eyewitnesses, the one who came at 6:30 was the 10th in line, and 100 people is an approximate numberthe number of people who are served per day, then the electronic queue is closed). This paper list is made so that after the opening (at 9:00) there would be no crush and misunderstandings. And then they start in parts and you need to take coupons in an electronic queue. If you can make an appointment early enough, I recommend staying closer to the entrance at 8:30. For 15 minutes before the opening, a lot of people run in, among whom there are violators of the established order, who will brazenly break through despite the general swearing and discontent of people in the queue. I was a little gawky and did not pull up to the entrance in time, and as a result there were 47 people in front of me on the ticket (but some of the coupons were canceled and torn out of the hands of the violators). At 12:30, I received the required paper. Accordingly, in total it took 6 hours.
Take food and water with you if you don't plan to go somewhere. There is no accessible toilet, as I understand it.
There are no questions about the procedure itself, everything was done in a few minutes.
