Cambodia:

U.S. citizens may enter. All travelers must present a valid visa issued by a Cambodian Embassy or Consulate. Visitors must also pay a $2,000 COVID-19 deposit at the airport for mandatory testing and potential treatment. Plus, a negative COVID-19 test result is required from no more than 72 hours prior to entry, and you must take a COVID-19 test upon arrival. On top of that, you must purchase a $90 local health insurance package for treatment. A positive test means an automatic, mandatory 14-day quarantine in a designated location. Travelers will receive another test on the 13th day. And a negative test still requires you to take a 14-day self isolation at home or lodging option.

Maldives:

It’s open for U.S. tourists, who must present a negative COVID-19 test from 72 hours (or less) prior to arrival. If you show symptoms at the airport, visitors will be required to take a COVID-19 test along with their entire travel group.

Philippines:

There is no entry without a Philippine visa, and no prior COVID-19 test is required but there is a mandatory test upon entry. The traveler will have to pay for this COVID-19 test, and there are also various health checks. You must book a hotel beforehand that has been accredited by tourism and health agencies and self-isolate there as you await your COVID-19 test results. It will take at least two days.
