Russian President Vladimir Putin has issued a decree further tightening security in Winter Olympics host city Sochi.
The decree published on November 15 requires all Russian visitors to register personally with local immigration authorities within three days of arrival, instead of the usual 30 days.
Non-Russians who do not require a visa will have to register within 24 hours, instead of the usual week.
The requirements do not apply to those with official accreditation, or visitors staying in hotels, both of which already require identity information.
Putin had already decreed a range of restrictions to be imposed in Sochi between January 7 and March 31.
Critics say the measures amount to a state of emergency. Sochi is close to Russia's restive North Caucasus region.
The Winter Olympics are to be held on February 7-23.
