Visa policy of Ukraine
Visitors to Ukraine must obtain a visa from one of the Ukrainian diplomatic missions or online unless they come from one of the visa exempt countries.
Travel visa
Some countries, including the Czech Republic, require that an alien who needs a visa on entry be in possession of a valid visa upon exit. To satisfy this formal requirement, exit visas sometimes need to be issued. Russia requires an exit visa if a visitor stays past the expiration date of their visa. They must then extend their visa or apply for an exit visa and are not allowed to leave the country until they show a valid visa or have a permissible excuse for overstaying their visa (e.g., a note from a doctor or a hospital explaining an illness, missed flight, lost or stolen visa). In some cases, the Ministry of Foreign Affairs can issue a return-Home certificate that is valid for ten days from the embassy of the visitor's native country, thus eliminating the need for an exit visa.
