这个是莫斯科机场官方规定:while waiting for a connecting flight, foreign citizens can stay in sheremetyevo for 24 hours with no russian visa issued. if the flight change requires a stay in sheremetyevo for more than 24 hours, foreign transit passengers can get a rf transit visa directly in the airport (if the ticket for continuation of the flight of the carrier and current identification documents are submitted). 如果转机时间不超过24小时,并且持有下一程航班的登机牌,那么就不需要签证,如果超过24小时可以在机场办理签证.友情提醒,俄航是著名的丢行李箱加晚点
