From November 8, to enter the United States, you must provide a vaccination certificate and a PCR test 
In the United States on November 8, updated entry rules entered into force for foreign tourists. They are reported on the website of the National Center for Disease Control and Prevention.
For example, when boarding a flight to the United States, all foreign tourists arriving on nonimmigrant visas are required to provide a certificate of vaccination against COVID-19 with drugs approved by the American the regulator or the World Health Organization (WHO), as well as a certificate in English with a negative PCR test result, no more than 72 hours before departure.
At the same time, Russian citizens who either did not get vaccinated or were vaccinated any Russian drug will not be able to get to the United States.
Minors and people with a medical withdrawal from vaccination are exempted from the new requirements – in this case, they will have to present a PCR test done within three days. Citizens and residents of the United States will be able to enter without vaccination, but in this case they will have to pass the test 24 hours before the trip.
Earlier in November, Russian blogger Ekaterina Novikova, who lives in Silicon Valley and travels around the United States, told the truth about the attitude of local residents towards Russians. The girl believes that most of the inhabitants of the region are friendly and calm people who do not feel any negative attitude towards tourists from Russia.
