This was reported on the website of the American diplomatic mission.
The embassy stressed that a trip to Russia could result in unpredictable consequences for US citizens due to a special military operation in Ukraine.
In addition, US diplomats warn of the risks of "potential harassment and detention" as well as the limited ability of the embassy to provide assistance to US citizens in Russia.
Earlier it became known that the US Embassy was handed a note demanding to stop interfering in the domestic affairs of Russia.
A source close to the leadership of the Russian Foreign Ministry said that the American diplomatic mission allows itself inappropriate statements about the Russian authorities and spreads fakes about the army.
