Kalisin told me last week that they couldn't guarantee the the covid extensions would continue as they don't know themselves. I've never had any problems there and always in and out within 20 minutes without the under consideration stamp hassle, as the passport is handed over straight away to the chief and she signs it off immediately. The only thing they were urging was to convert a long stay visa if I could qualify. I can't qualify because I'm not old enough and I'm not wishing my life away to get one and I don't want to get married either.
Personally, I can't see these covid extensions stopping until the land borders reopen. These extensions are reviewed on a case by case basis. If somebody arrives on a one month return ticket and the airline is still operating that return leg on that date, I'd say no comment.
