MOSCOW, April 4 (RAPSI) - Starting April 7, Ukraine’s State Border Guard Service (USBGS) will verify if Russian citizens in the country have overstayed their legal time limits in Ukraine, the USBGS announced Friday.

Russian citizens who will arrive lawfully in Ukraine may not stay in the territory for more than 90 days during any 180-day period, except in certain cases as provided by Ukraine’s international treaties. 

Previously, Russian citizens were entitled to spend up to three months in Ukraine, but were able to re-enter promptly after exiting the country following the three-month period.

USBGS has also stated that Russian citizens found to have violated the rules would not be allowed to cross the border ever again. Those found to have violated the rules may face administrative measures as well.

On February 22, Ukraine’s Verkhovna Rada (Parliament) impeached Viktor Yanukovich and amended the constitution. Presidential authority was assigned to parliament speaker Aleksandr Turchinov and a presidential election was scheduled for May 25.

Russia has denounced the events in Ukraine as an armed coup. President Vladimir Putin said during a news conference in March that Yanukovich remains Ukraine’s legitimate president.
