PHNOM PENH: The US Centers for Disease Control and Prevention has decided that all foreign or immigrant passengers over the age of two must have a valid immunization certificate and a negative Covid-19 test result no more than one day before departure or Covid-19 recovery certificate. This is according to the Embassy of the Kingdom of Cambodia in the United States.
For Americans, whether fully immunized or not, the Centers for Disease Control and Prevention still requires a negative Covid-19 test no more than one day prior to departure or a Covid-19 recovery certificate.
The new US measures take effect from 6 December 2021 onwards.
