"A decree which also set out restrictions on foreigners' entry continues to be valid. This is Government Decree No. 641. At the same time, it imposed a ban on foreigners' entry to the territory of our country precisely from August 28 and until 00:01 a.m. on September 28. Thus, as a matter of fact, this norm that banned foreigners from entering our country ceased to be in effect overnight. From now on, foreigners are allowed to enter our country," said the State Border Guard Service spokesman Andriy Demchenko.

Currently, to cross the border, foreign nationals must have an insurance policy to cover possible costs associated with COVID-19 treatment and observation (issued by an insurance company with a representative office in Ukraine).
