Good mornign.
I would like to get information regarding any restrictions or requirements for the foreign countries citizens which are going to bussines trip to Phoenix at the end of November. Is it neccessary to kepp 14 days carantine after arrival? I am from Russia and going to Phoenix for 5-6 days bussines trip. My flight most probably will be Russia ( Moscow ) - Turkey ( Istanbul ) - Los Angeles - Phoenix. Do i need to do CPR test before flights? How many days in advance?
Your advise will help me to plan my trip.

Thank you in advance.
