If a foreigner comes to Ukraine under the visa-free regime, it is not necessary to additionally apply for a visa. Foreigners can stay in the territory of Ukraine for up to 90 days. It should be remembered that the period of stay of foreigners and stateless persons in the territory of Ukraine is extended in the event that they arrived from countries with the visa-free entry procedure if there are valid reasons (treatment, pregnancy or childbirth, care for a sick family member) and subject to submission of supporting documents - for the period of existence of such grounds, but no more than 180 days from the date of the last entry into Ukraine.

Persons who do not have the right to enter Ukraine under the visa-free regime must apply for a short-term visa (type C). A visa of this type is issued as a single, double, or multiple-entry for six months or another period specified in the documents, which present the basis for issuing the visa, but for no more than five years. In this case, the basis for issuing a visa will be an invitation from a medical institution of Ukraine.
