Russian immigration card (immigration card)

You don't need to fill in the disembarkation card on the plane. When you enter the country for border inspection, the border inspector printed two copies of your entry card. The introductory copy, he (she) left on the spot, and the other one will be given to you.

If you lose it, you can go to the local immigration office as soon as possible to reissue it. Otherwise, there will be some trouble leaving the country, and there will be trouble in handling hotel accommodation procedures in Russia.
