The organization of work is excellent - we received an American visa, spent 7-10 minutes on everything, BUT!!!! We were in Astana for an interview on Tuesday, as it turned out on the eve of Nauryz (Nowruz) and nowhere (NOWHERE!!!) There was no warning that there would be days off from Thursday to Monday inclusive. On Thursday morning we arrived to receive the documents, the notification that they were transferred to the delivery service came on Wednesday after 16:00, and the office is closed until Tuesday! And there were many such people. The security of the business center says so every year.
Add weekend alerts, especially if it's several days in a row, and you'll just be "great"
Services are expensive, many consulates took over the reception of visa documents, and the room was rented tiny, hundreds of people, a crush. Everyone is pushing, breathing down their backs, not because they are bad people, but because there is not even room to stand. It's a pity there is no choice where to rent more.
