"In 2015, out of humanitarian considerations, the migration service has been repeatedly extending the period of temporary stay in Russia to all categories of Ukrainian citizens. The deadline for the extension ends on October 31, 2015. In this regard, from November 1 to November 30, the citizens of Ukraine who are staying in the territory of the Russian Federation must report to the Russian Federal Migration Service offices to determine their legal status," says the statement.

At the same time the deputy head of the FMS, Vadim Yakovenko, said that all of the regional migration offices had been instructed on providing maximum support and maximum attention to Ukrainian citizens.
