I am a Nigerian studying in zaporozyhe

Etuaje, if you are Nigerian citizen, I'm not sure whether the embassy will issue you the tourist type PRC entry permit. If it can issue you this, you need to provide all necessary documents, like your passport, passport copy, application form, recent photo, round-trip travel tickets, hotel reservations, financial standing proof, etc. There is no consular office in your city. You should go to the consulate in Odessa. The address is Lane Nakhimova 2, Odessa, Ukraine, 65014.
