The new Method to do Medical is very complicated. First you wait twice until you get the first ticket on the 4th floor. Then from there you do the translation and pay around 1500 Rubles. Keep in mind that you should keep the card or exact change for cash but since they charge you for commission also it's better to pay with a Card only. Second you go and wait for another token, where they give you paper to do medicals. You pay 7500 Rubles there. Third you go for Fingerprinting, you pay 1500 again and then you go and actually do the Tests.
Then when you receive the results just go to the counter and give them paper. They will call your name. If it's your first time go directly to Building 15 where you can get the green card and Letter of confirmation.
Treats foreigners as troubles and not guests of the city. Why let them in on the first place if you don't know how to handle their documents. The people working there are rude and unhappy.
