How long does it take for the Immigration Bureau to cancel the visa?

After issuing a Russian visa, the embassy announced the withdrawal and cancellation of the visa, which is called visa cancellation. Under normal circumstances, the visa is revoked mainly because the holder is found to be unqualified or unsuitable for obtaining a visa, and the holder loses his visa and passport and reports the loss. In order to prevent criminals from using it, the embassy revoked it. /zd/ym
