Can I fly on the Belarus study visa if it is overdue for two days?

You need to apply for a new visa in time, which is the same as the materials submitted when you first went to Russia to apply for a visa. The copy of the notice from the school and the original invitation letter from the Immigration Bureau, the medical certificate, the bank deposit certificate, two 2-inch passport photos with a white background, and the copy of the contract signed by the school. If you don't return to Russia on time within the validity period, you need the Russian school to send you a new letter. If you are about to expire within the validity period, please go to the Russian consulates in China for extension as soon as possible. May need Russian school certificate, etc. Check your visa date in time in case it expires halfway.
