I just lost my Russian entry card, but it's been a year. What should I do now?

For рвп, the immigration card is not very important. General airports can reissue them, or go to the local Фмс to learn about the procedures. It will be easier if you have a copy or photo of the immigration card. If not, it doesn't matter. The customs system has records. As long as the talks are good, they will usually be reissued.
