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.
Soviet Union passport
All residents were required by law to record their address on the document, and to report any changes to a local office of the Ministry of Internal Affairs (e.g., by the age of forty-five, a person has to have three photographs of himself in the passport due to the effects of aging, taken at the age of sixteen (when it is issued), twenty-five and forty-five). In Ukraine, these laws were abolished by its Constitutional Court in 2001 on the grounds of unconstitutionality. In Russia, similar cases have so far failed, and the system remains in place, although largely reduced. The system of internal passport registration remains strongly in place in Moscow, which uses the recent terrorist attacks on that city as a justification for their continued use.
